I became a dronemaniac about a year ago and, being a technicaly skilled engineer, I am surprised that every time I watch one of your videos, I learn something new and important! I have to admit...you replaced Netflix on my tablet when I go to bed! Great job and I am watching all and every one you post...often several times!
@@Painless360 hi. I screwed up my ESC of no name by wrong calibration with my tx16s radio as I was not aware of the tones. Is there any universal way of returning the single ESC 30Amp to the original setting (factory reset) somehow? How?
I have returned to RC (20 years of building/flying/crashing planes) after a 10 year lull and have explored multirotors. I have spent a pile of cash teaching myself how to build and crash but have managed to learn basic FPV. Your You Tube video channel is like the University of Modern Radio Control and should be a must for all old timers re-entering the hobby. Thanks so much for all you have taught me!
THANK YOU SO MUCH!!!! I had a Blackfoot about four hundred years ago and am wanting to get back into the hobby with rock crawling. This stuff is all new to me and easy to understand videos like yours are a life saver. Thank you so much!
Forgot to mention, I started the build of a Hexacopter which I design for high payload and precision flying. Needless to say, your contribution to my project is incredible...I think I will print a small sticker with your logo and stick it some where on the final chef-d'oeuvre!
Learned a bunch. Thanks! Putting together an FMS PT-17 and know almost nothing about today's RC radio tech, especially electric powered, so trying to get up to speed. Used to love flying gas/nitro planes using now-extinct FM radios. Was always worried someone would accidentally turn on 'my' channel 42 and crash my beloved plane. Glad that old tech finally slithered into the tar pits. Gotta say that today's RC tech is freakin' extraordinary! Cheers from Thailand!
+Jimbo in Thailand glad it made sense. I came back I to RC just as the old tech was dying off. There are lots of basics about current technology in the 'Introduction to Remote Control" series. Happy flying!
Being a newcomer to this hobby trying to wrap your head around all the theory takes a f***ing university degree. At some point - usually around here with ESCs and BECs - smoke is coming from your brain and your hair is catching fire but you can't put it out, because your eyes are pointing in different directions. But dont worry, it's all fun and games until you realize everything you watched and read was made back in 2012 and everything's changed since. Yay!
+iMeMySelf stick with it, it'll all make sense. This video is part of a series that's designed to cover the basics and everything in the series is still relevant. Sure, they've been improvements and changes and firmware additions but the basic principles underlying everything are still exactly the same as they were 10 years ago. Best of luck with your journey in the Hobby
Thank you @Painless360 all of a sudden, everything fell in place. You were right, it's weird and I can't explain it but you were def right about going back to the basics. Then updating on progress made since that time is easy-piecy!
Think I found my new favorite youtube channel... Your helping make a hobby that seemed exclusively technical, overwhelming, and not accessible to anyone not working for NASA..., into a doable, fun, and educational hobby that will open up whole new areas of knowledge and interest for many people including me. Particularly in today's world,That is as commendable and needed as much as any charity or good deed could be. Good on ya and Thanks :)
+DanielVision Thank you for taking the time to write that! It's always nice to hear we are helping others understand some part of the hobby. Happy flying!
TOTALLY THE BEST, DEFINITION(S) OF ESC I HEARD ON THE TUBE ! AWESOME INFO, NO freaking overriding background music etc., Very Professional in my book! T H A N K S
Thanks for helping all of us newbies. All your videos are clear, to the point and without the a noxious background music present on too many. ...and, by the way, for people who grew up with 2-stroke engines and 27MHz radios, there’s a LOT to be learned...
There is but the hobby is even more fun now with the amazing tech about. Once you've got to grips with the new digital radios and eleectrics power systems then you'll be back flying. Have a look at the 'Introduction to Remote Control' for more of the basics videos. I'm starting a new series next month that looks at the common questions from 'new' and 'just come back to the hobby' pilots so please keep an eye out for that too! Happy flying!
Robert Blitek Tanks for the feedback. Some good 'Introduction to.." playlists in the channel that may be of interest - ruclips.net/p/PLYsWjANuAm4oWuE5ZDX4TAiHBv2i0Xl4m, ruclips.net/p/PLYsWjANuAm4pIU07ta7glYIn-EBCof_4r and ruclips.net/p/PLYsWjANuAm4rQfddw-7YZDzckoJ_KyOpm Best of luck.
You have a great channel. I recently picked up the hobby again after a long hiatus (since teenage years). Now I will finally finish my Tamiya Gepard (with custom gearbox), together with my son! I am so much realizing how much we were in the dark back in the era before Internet and RUclips! By the way, I now work for one of the leading manufacturers of small DC drive systems, so I have a much more professional angle towards the hobby. Still a lot of fun!
Welcome back to the hobby. A lot has changed in just the last two years. It's cheaper, we have more power using LIPOs and brusless motors, the parts and models are easier to get and repair and you'll need to reach for as PC more often now than in the 'old' days. It's even more fun now! Best of luck with the model and getting back into it all. The series called 'Introduction to Remote Control' may be a little noddy for you but may act as a reminder.. :D
Yet another great video Lee. Thank you for what you are doing for the community buddy. Without people like you, excuse my french, I would be screwed. Thank you.
HI YOUR VIDEOS ARE GREAT .i JUST GOT INTO qUADS AND YOUR VIDEOS ARE THE BEST! i HAVE LEARNED A LOT FROM THEM AND IAM A OLD TIMER BE VERY CLEAR AND EASY TO UNDERSTAND, THANKS.
Now I run over a topic related to the ESC, that I find interesting: What does the frequency do and what does it mean for a motor - ESC combination? Is a frequency lets say 600Hz better than 450Hz? Or is there a kind of rule - lower kV lower frequency or does it have to do with the number of poles od a brushless motor? With a program card or with the TX the Hz is adjustable, but what is recommended for multicopter?
The frequency is the speed of updates to the ESC from the FC. Analogue servos and traditional ESCs normally update at 50hz or 50 times a second. Sounds like a lot right? Well, in practice a 50hz rate isn't enough for more aggressive moves with faster speeds so firmware like SimonK 6x the update speed and faster response were created. The pulses to the motor are managed by the ESC to match the throttle needed. Hope this makes sense.
Painless360 So does this mean if I have the option to choose between 490Hz and 600Hz, I should switch to 600Hz? (asking for Hobbywing XRotor black series ESC) Thank you.
Very very educational. Best ESC explanation. My quadcopter got lost and was found a month later upside down in a puddle of water with battery missing. I cleaned it and dried it out and checked to make sure all the motors still turned freely by hand. After installing a new battery, i tried to fly it and it lifted off and hovered at 4 ft or so as usual but as soon as I tried to move it to the left, it drifted away and wouldn’t come back. I had to run after it to stop it. Could a bad ESC cause this drifting away issue?
I used 30A ESC and a 3S lipo battery in my quadcopter. After arming the motors a strange beeping sound(1 beep) was coming from the esc s and the motor did not run when I turned on throttle. What should I do? Can you help me in this case? I'm using sp racing f3 flight controller and using i-bus connection. Actually I couldn't calibrate 4 escs at a same time with i-bus connection. Do I need to calibrate esc individually? And do I need esc calibration every time after first calibration?
in outline to FCB (Flight controller Boadr) they esc always have 3 line cable, is Bec Output , Ground and PWM input. so how with if the ESC just have 2 line. (Bec output & Ground) no line for PWM input. can i use this or how to do, ???
Hello Mr. Painless360, I've got some Optio ESCs (emax 40A) and trying to understand how to setup.@18:18 you say something about an "incoming rail". What do you mean? I just cut all the red wires from the ESCs to the flight-controler and then power only one of them on the side into the flight-controller from a seperate ubec, right? Thanks for the effort you're making with these videos, much appreciated.
thank you this is very helpful...i have quadcopter that only has two wires for each motor as they are brushed motors..the motors burn up allot ..i was wondering if there's was way to run the brushed motor in this quad with one of these speed controllers? or am i just crazy ..i'm a newb to this stuff ..i'm a mechanic too so i'm able to fix stuff..but only if i understand it ....which i don't at the moment
Not easily, brushed motors are used on the cheaper models. you dont mention the model you have but you could google for a brushless conversion kit for it. Best of luck!
I have since bought 12v dc 0.18a brushless 2 wire fan. I bought a pwm controller to vary the speed but the fan did not even turn with the potentiometer in either position. Struggling to get any info even from suppliers. Can you advise what type of controller I need for this type of fan? Thankyou. Great videos.
Thank you ! So much to learn and things are constantly changing or being updated. Nice to have some where to look to find details in layman's terms backed by real knowledge.
hello, Im working on a project - if i wanted to make a homemade leaf blower... can i just run a 90mm EDF to a 22.2 lipo or do i need a 120v esc with a on and off button? thanks for any info!
Almost, an ESC needs a 'PWM' signal to know how much power to send to the motor. In addition to a switch you will also need something like a 'servo tester' that can send the signal to the ESC for you.. Best of luck!
@@Painless360 ok, heres what im getting ready to order - Dr. Mad Thrust 90mm 11-Blade 1700kv Motor - 2300watt (6S) YEP 120A HV (4~14S) Brushless Speed Controller (OPTO) Turnigy Heavy Duty 5000mAh 6S 60C Lipo Pack w/XT-90 Turnigy Reaktor 300W 20A 6S Balance Charger now with NiZN and LiHV HobbyKing™ Servo Tester SKU: HKSESC_TST. I think everything looks correct? please and thanks for any info!
Great video! How can I tell if an ESC is going out? My quadcopter drifts to the left and forward after flying for a bit. Also, the front left motor doesn't seem to have the brake control working . Usually if I flick the props with my finger they don't spin while connected to the esc's. The front left one now spins freely when connected to the esc.
+Jeremy Dockter Sounds like the settings on one of your ESCs is different. That on it's own can cause problems like you are seeing. Normally ESCs fail in a dramatic way..
Very good video again. Can you tell me why my 20amp esc operates fine with a 3s li-po battery but when trying to use a 3S li-ion the throttle starts to play up. Full throttle and speed then begins to fall and then motor violently pulses
Hi sir i have a question i have linear 30A escs.how do i wire it up to a tcmmrc f4 flight controller..im stuck on the part where the big red wire and black wire setup and then the smaller wires signal..ground ..you said in one video about not using red wire so i took them off.can u make a video on this..thank you
I'm guessing you're not a regular viewer. If the ESCs have linear BECs then you can connect all the red power wires to the FC without a problem (normally). See my recent 'basics' video - ruclips.net/video/xPDc6r6nRTU/видео.html
The throttle setting controls what exactly in the ESC? Is it RPM? Is it voltage? What happens when the propellar spins faster than the throttle setting (lets say you have a variable pitch drone doing a dive and the upward winds make the props spin faster as gravity makes the drone accelerate pass terminal vel).? Will the motor try and slow it down?
+RoboticSolutions.TECH an electric motor is actually a constant velocity device. It will try and maintain a constant RPM irrespective of the power supplied. That's what the KV is all about it - tells you how quickly the motor will turn for the voltage applied. What the ESC is actually changing is the duty cycle of the waveform that sent to each of the motor coils in turn. The throttle signal increases the amount of 'on' vs 'off' voltage the each motor phase gets in a high frequency waveform. There are some excellent videos and articles online the explain this in a lot of detail. Best of luck
Please dont wish me luck and send me on my merry way yet. You didnt answer my question. If wind pushes my propeller to spin faster than usual at the specified throttle setting so that its RPM is way above what it normally would be, would the ESC and motor attempt to slow down the RPM? So lets say I set my throttle to only supply 1 volt and the engine is a KV1000. But I put my variable pitch quadcopter on a dive with negative pitch so the propeller now spins at 2000RPM without changing the throttle setting. What happens? Will the Engine and ESC supply negative torque to try and slow it down or will it keep pumping 1 volt in to re-enforce the 2000RPM spin? Or will it just supply no voltage at all?
So the wires of my motors have 2mm male bullet connectors and the wires of my esc’s (the exact same as shown on 19:16) are about double the size in diameter. And have no connectors. Is there any right way I can connect them?
Pretty much, as long as the ESC is rated for more current that the maximum the motor needs. Some motors may need tweaks to the settings though (advance etc).
Hello. I'm intent on using an RC motor in a project and have a 12V power supply and a PWM all set to go. Is it possible to connect a brushless to the PWM without an ESC or is the latter a must for brushless? If so, what motor then can I just connect to a PWM in just cutting the wires and attaching it? Your diagram and animations are informative BTW 'cos I'm learning as I go with this stuff.
ok, i'm in a bit of a conundrum.I was trying to use a brushless motor (thanks again on clearing that other question up, btw) and my intent is to use a 12v power supply connected to a PWM which is then connected to the brushless motor. This is is all for a project. Question: am I mental for thinking this will work? Power supply: www.amazon.com/gp/product/B01N0O646U/ref=oh_aui_detailpage_o01_s02?ie=UTF8&psc=1 PWM: www.amazon.com/gp/product/B01H1W79S0/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 Motor (I'm returning this one before I make the mistake of overloading it): www.amazon.com/gp/product/B01149JBNC/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
Hi! Great video and great explanation! I’m currently building a quadcopter using an APM 2.8 and maybe you could help me solve some questions I have. I have LD Power ESC’s with NO BEC’s. Does that mean that to power the APM I should leave the JP1 INSIDE to power the whole APM with the 5V the power module provides and leave the power cables from all of the ESC’s connected? In that case, will those 5V the power module provide be enough to power the whole APM or could I have voltage shortage problems, or over voltage problems coming from adding the power module voltage and the ESC voltage (with no BEC the ESC’s should not be powering the APM at all, wright?)? Thanks in advance!
If I have an ESC with a linear BEC, do I have to connect the BEC, or can I just cover the end of the red wire with some electrical tape? I'm thinking of using the radix PDB, so I don't need BECs, so is it safe to just not connect them, or would that damage the ESC?
If it's linear then you should be able to connect all the red wires fine. See the other videos in the 'Introduction to Remote Control' series on the channel. Best of luck!
I have these Tarot 40A 2S - 6S ESC OneShot & SimonK Firmware with 5V BEC - TL2953, the specs say they are linear but you mentioned that linear are only for 4S Lipos. I have 6 of these going onto my Tarot 680 hexacopter, so now I'm a bit worried as to the suitability of these ESC,s.
They will be fine but I'd not use them to provide the 5v the flight controller and pieces need. I'd power it using a dedicated 5V BEC.. See the other videos where I cover this in the 'Introduction to Remote Control' and 'Quadcopter building for beginners' too..
many thanks, I'll take a look at your videos, my tarot build has turned out to be a bit of a nightmare, but at the same time a very interesting learning curve. Thanks again.
Thanks for the video learned a lot but I am working with a Mystery Fire dragon 80A ESC and still figuring about how to program it to go backwards and revers like a in an RC car and how to control it with a single signal wire.
+Derpy Herpy the answers for these things are usually in the documentation. If it's not then it's not supported. I'd ask the vendor the same question..
+Painless360 do you know of any ESC that has that feature of going forwards and reverse? If not I'll probably have to work hard to program the AVR cheap on the board to have that function..
So I know of 3-phase motors from commercial A/C work where I swapped electric leads to change the direction o f spinning but can you likewise change the propeller backwards to essentially do the same thing or are the propellers notched in a way that they'll only work in 1 direction? And I imagine some manufacturers can be swapped & others have their own, "Notched Groove" to make sure the propeller turns the right way? I'm trying to get a basic set of, "Wants/Needs" put together for my flying. Ultimately I want one Transmitter(easiest/user friendly) & it needs to have several, "Flight Controllers" it can support/handshake with? Once I can establish this main issue I can have any number of other components fall into place. My mind is whipping along......
Props can't be reversed and have the same thrust and efficiency. With a very flat profile and minimum aerofoil you can design a prop that can go both ways but most can't.. Hope that helps..
@@Painless360 >> The "prop" example I was asking was not to run it in reverse But to pull it off the shaft & remount it the opposite way. But I digress, you've helped me to unlock my brain a little bit with your skillset(s) & I've got to learn some other things before I can ask you any intelligent questions. This will take me a few days but I'll shout out when I reach saturation or I get to a place where I'm about to spend $$$.....lol, I've been taking my time to ensure that I don't spend monies I don't have on stuff that I can't use. Thank you again & I'll be somewhere in your vast library...… I'm glad you have one!
Have received my skyfun todaty with a 25Amp linear esc bec but i have no idea how can I use a separated batery in order to control telemetry in one side with its own Bec and the motor and throtle in the other ... do you guys have a video showing how to use 2 separated batts for tha5? Thank you ;)
Is a brushless flight esc usable in a rc car with two Motors? Like the old wild dagger from tamiya? Because there is only brushed dual motor Controller for cars i can find.
Hi Painless360; ESC Opto is the same as Optio? I'm using the E300 and says 15 A Opto. And sorry but with the Optio you have to connect just one ESC with three cables and the others ESC's with the signal? You no say it in the video. Sorry for too much question Painless, but thank you very much.
Hi! I just want to know if how many esc is allowed to be fitted to a 6 channel receiver if i place 5 esc for 5 motors on the esc and only 1 servo this 5 esc won’t damage the receiver? Since esc supplies 5v power to the receiver? Thanks 🙏
nice video, well i need to know some simple questions? a brushless in market is marked as Kv( i:e; 1000Kv, 1400Kv, 2200Kv) but ESCs are marked as 'A" (like 15A, 20A, 30A, 40A etc.) As i know always use 20% higher ESC. SO MY SILLY QUESTION IS THAT FOR 1000Kv brushless motor ESC required? (in A please) FOR 1400Kv brushless motor ESC required? FOR 2200Kv brushless motor ESC required? and please tell me propeller for each ?
It's not silly at all, but it sounds like you are very new to the hobby. Please watch the other videos in the 'Introduction to Remote Control' series. A lot of the basics in the hobby are covered in there. KV and Amp draw have no direct correlation. Best of luck!
i have seen all of your video but din get the answer. sorry but neither in your reply. every one is making it too complicate for me. i understand simple things. i just want to know my answers because it will help me to go one step forward to my goal. i will learn by the time, and believe me i am learning, i know the roles of each and every electornics of rc plane. OK i make it easy i have a 1000Kv brushless motor + 30A ESC + 3 Servos + lippo 11.1V 2200mAh battery. IS IT A COMPATABLE CONFIGURATION FOR A RC PLANE?????? IF YES THEN, WHAT SHOULD BE THE PERFECT WEIGHT OF THE PLANE INCLUDING ALL ELECTORNICS? AND WHAT SHOULD BE THE PROPELLER SIZE????? please don go into too much technicality it just complicate every thing.
I can't answer the question as you don't tell me what motor it is. The KV is how fast it turns, the amp rating how many amps the motor needs. You need an ESC with a 20% higher amp rating than the motor needs. All covered here - ruclips.net/video/DraFgiDELjI/видео.html If you're still not sure then book a chargeable support call via the website. Best of luck.
fantastic sir...this is the thing i was looking for mainly the BEC part...i am usuing a 12amp simonk with BEC with cc3d open pilot and i was wondering whather i should pop out the hot wires from the remaing 3 or not...you make me to take the right choice...mine are linear...thank you :-)
I want to get the complete step by step procedure in setting up my Flysky FS CT6B to control a Sabertooth motor driver for 2 wheelchair motors. After I purchased the Flysky system I discovered not everything I needed to make it work was contained in the box. I became aware that I needed a separate power source for the receiver. Then I became further confused with ESCs & BECs. I'm talking about connections, current requirements, etc. My Sabertooth driver is dual 32 amps.... This all new to me.
+William Gunter all of the basics for radio control, when it relates to radio control models, are in the 'introduction to remote control' series here on the channel. This video is part of that series, hopefully the other videos will help. Best of luck
What does the "35A" mean on the ESC. I know it means 35 amps are supplied to the motor, but how do you determine that when picking out the correct esc to buy?
You normally choose an ESC with a higher rating than the max amps a motor will draw. I usually go for one 20% higher rated. See the other videos in the Introduction to remote control playlist.. best of luck
Which way up are the 3 wires on the connection from the ESC to the Naza Mv2 main controller? My new speed controllers have Black Red and White wires to the connector. My old ESC's had Brown Red and Orange with the brown uppermost.
Hi, Thanks for your kind videos, they help us alot. I have a doubt, I have gone through with various papers and found that ESCs should not run on low throttle say 50%, do u also think the same about this. As it will generate more heat. If yes? Can we calibrate our ESC at 50% throtte i.e. 1750 and then if we run it, so for us it is 50% but for ESC it should be considered as 100% throttle right? If yes so can we use this method to run continuously.
I'm a bit unclear on the OPTO ESC's. I was planning to use my OPTOs for motor only and using a separate 6V batt to power my servos etc. Do I need to use a separate BEC or can I just plug the 6V battery pack into my receiver BATT slot? Thanks for these videos, I subscribed.
Hey man great video tutorial very easy to understand, so thanks. I'm thinking of building copter but with a difference, I want to build one with 3 lift motors and two propulsion motors. So in otherwords 3 motors in the y axis and and 2 in the x axis. I'm just getting up to speed with ESC etc and wanted to know in principal would it be possible to control this set up and how one wuld go about wiring it? All help gratefully received
Wow this is so useful! Just in the middle of building a scratch build wing and having clicking noises and warm motor, using a traditional esc type. Looks like the timing is my issue?
I have a question. I'm very new to these types of motors and speed controllers. And it's very nice to watch this video and understand how the motor and speed controller works. I learned a lot! And I thank you! But why is it that I can't use a standard wall plugin, to power the speed controller and the motor? I plug it into a lipo 2 cell and it works fine. Plug it in using a wall plug and it only gives a slight kick and then nothing. Any help on this would be greatly appreciated! I'd like to use the parts of a broken and older drone, to possibly use on an airplane, or glider with the speed controller and motor assist. I tinker with arduino's, and that's what I have the motor and speed controller plugged into. An Arduino Nano. Again, any assistance on this would be greatly appreciated!
@@Painless360 Plugged into the wall using a wall wart, plugged into an ac outlet. What is the voltage? Or won't it work because it needs a certain amount of amperage?
@@Painless360 That's what I thought. And it's the high amount of amperage in a lipo battery that is dangerous, right? Because the voltage is only 7.2, but the amperage is far greater than that in a common 9 volt battery. Thank you! I appreciate you taking the time to explain that for me! I'm only dealing with the small amounts of electricity needed for an arduino, 5, 9, 12 volts with very little amperage. Again, thank you!
I have a Parkmaster Pro 3D plane from MPX, and I'm noticing a fairly long spool-up time of the motor when I apply direct full throttle. In the sim, and from videos I've seen on youtube... throttle response seems waay quicker. It is pretty annoying eg. for hovering the plane. My plane also makes a weird electronic noise when making small throttle adjustments at high rpm. Am I dealing with a faulty esc? Or could I be doing something else wrong? Everything works fine, I just suspect the fairly indirect throttle response is not mormal. Thanks in advance!
I'd look at what kind of ESC you have in the model and see if there is a setting for slow spin up times. ESCs designed for larger props move to the new throttle position over a small period of time to allow the mass of the blade to catch up and increase the thrust gradually. These settings can usually be altered.. Best of luck!
+Painless360 Thanks for the quick response! My ESC is (as I read it in the manual) a "MULTIcont BL 30 S-BEC speed controller". I will look further into it, been flying a lot today and I'm getting more used to it... maybe I'm seeing ghosts afterall. Thanks for your info, I subscribed to your fantastic channel too :)
Hello, My question is if I am running 4 ECS without BEC then my options are to either get a 5V regulator or buy 1 additional ECS with a switch BEC and replace one of the original 4 inorder to power my Naze 32 F3 acro 6 and my X8R? Thanks
Okay I watched that video. The thing is I am using the Alien frame that has the built in PCB but doesn't have the 5V output. So I could either get a 5V regulator or switch one of my ECS with a switch BEC correct? Best bet would be to get a voltage regulator right?
I'd use a separate BEC as swapping out just one of the ESCs for something different can cause stability and calibration issues. Best of luck! (can't believe they don't provide a better PDB on a frame that expensive..)
I am college student, and we are working on small team project this quarter. we planed to build a control moving platform can hold 50kg(with one 4 inch wheel). we have GForce 400kv motor, 120 ESC Brushless speed control, 8.4V battery, and 2.4ghz Radio System Transmitter. After we contected all parts, the motor only worked twice, then never work anymore. Could you tell us what's problem we might have and how to make it better? Thank you!
+ubbelohed Wu this is a little outside what we normally do here. But normal troubleshooting rules will apply. I'd check the motor driver and wiring as a first thing, then start to look at the logic and firmware on the controller. Best of luck with the project.
Hi Lee, I'd love to have your opinion: Just finished a new quadcopter build. I'm using Hobbywing xrotor 40A Blheli32 ESCs and 935kv brushless motors, pixhawk 2.4.8. All flashed with latest firmwares. When testing the system, 3 of the motors seems to be ok but the 4th is just jumping back and forth not getting into smooth rotation to either direction. Any idea? Settings / esc problem / motor problem (all components are new). Thanks!
+Painless360 I am in the process of building a Blackout mini h, currently I have run into some problems. When testing my motors using Cleanflight 2 of 4 ESCs let out the magic smoke and possibly ruining the motors as well. I am sure all the pros check their ESCs before soldering to the PDB and to the motors, but to us newbies we just solder on and hope for the best. Unfortunately I learned my lesson the hard way and I will be getting a multimeter to test my ESCs next time. Some of us do not know how to check for continuity on the ESCs and/or the motors (including myself) so I thought it would be a great idea for a pro like yourself to do a video on that.
Very useful vid, after a 15 break from RC planes the electronics have changed a lot, in my ignorance I’ve ended up buying a Emax SimonK esc for my model glider, will there be a problem as this is a multi rotor ESC or can I use it in my glider with no issue? Thanks for any help
It will work fine. SimonK just removes the ability to change the ESC parameters you'd normally expect to be able to change (like breaking for example)... happy flying!
Thanks very much for the prompt reply, really appreciate it. Does that mean I won’t be able to programme in engine break as it’s going on a glider with a folding prop?
Painless360 thanks very much, was just hoping there would be a easy solution. Last question, any recommendations for a decent inexpensive ESC for glider application?
Together with a colleague, I am looking to drive my tank with two BLDC (outrunner) motors (one for each track). We may use an Arduino to make a "digital differential", like some of the Tamiya DMD controllers. We're still in the early stages so I'm now exploring the current state of technology of RC, which your channel is proving to be of great benefit. On my channel there is an animation of the "Cletrac" differential, which is a very nice mechanical concept, although hardly suitable for RC.
You could also use a mix inside the transmitter you are using too. Look at the videos of brushless motors on twin engine 'planes. They use differential thrust to turn. Maybe that could work mixing the throttle channel with the channel you're using to turn? Best of luck with the project!
Thanks so much for your quick replies! I did consider this and will have to dive into it deeper. A requirement is that the tank does a "neutral turn" (pirouette). In the Tamiya controller, past a certain (steering) stick position, the motors will spin in opposite directions. Earlier my tank operated with two brushed motors, two Tekin reversible ESCs on two identical up-down sticks on the transmitter. This works fine but I really like the idea of controlling it as an RC car, but with the added "neutral turn" functionality. I will be uploading a video soon on the custom gearbox I already built (more than 20 years ago) and how we'll redesign it into a "high tech integrated drive system"!
Quickly researched it... looks like any transmitter with mix functions will do the trick just fine... thanks again! I'll have to find another project for that Arduino...
Can I connect the three wires from the motor to the ESC then from the ESC to the battery without the transmitter as I only want it to operate a hairdryer..Thanks
i have an sk450 had a crash and i damaged one of the escs im trying to get a better understanding of quadcopters , how they work , Can i use a afro 30 amp esc with bec on the kk 2.1.5 board? , since the kk board needs power to operate on 5 volts .
neo36w eno36w Yes you can, having all the ESCs the same helps make sure the firmware is the same on each arm. I have two playlists you may find useful - 'Introduction to RC' and 'Introduction to CC3D'. Both cover a lot of basics...Best of luck.
+Lim Heng Yip Vincent it's the amount of amperage it is rated to supply. You want an ESC that can support more current than your motor needs. See pur other videos in the Introduction to RC playlist and the Quadcopter building for beginners series. Best of luck!
I connected. My xxd 30a esc with 1000kv motor then to a 11.1v battery. One of the voltage regulators started to heat and melted the heat-conducting rubber. What could cause this? Do you have to connect the three-wire signal cable to the controller board before connecting battery?
+Painless360 , please give me any idea. Is there any problems with syncronisation of the motors when you shortened wires between motors and esc? I made a rebuild to 210 frame from 250 (it worked perfectly for some months) and cut the wires between esc and motors to the lenght about 1,5sm and now when I use Damped light option motors randomly stops on rpm increasing ( not direct throttle, but rapid yaw or pitch input, none on roll). I have little bee 20a and dys be1806 2300kv. Tried to play with timings in blheli suite and other features like demag compensation, start force etc. nothing helps. Turn of damped light helps. But it worked and nothing changed except wires esc-motor length(((
+Painless360 Want to share my decision - yesterday I've flashed esc's with 14.6 blheli instead of 14.4, and there is one new feature - Break on stop. I've turned it off and Damped light works now without desync. Thank you.
Hello! You have said that Switch ESC what I use in my model, if I use four of it, I need to disconnect the *RED wire. What does it mean? Can you explain more? or Do you have any link to work with that? or Another easy way to explain by text? Thanks for your kind!!
im getting the Turnigy Multistar 20A V2 ESC With BLHeli and 4A LBEC 2-6S . im just wondering how to connect them do i need to remove the red wire from 3 of the escs and just one esc with all the wires comming from the bec ?
neo36w eno36w Find out what style of BEC they have in them and watch the video again for your answer. I would only connect all the red wires if its OPTO or linear BEC (with caution)..Best of luck with it!
Thank you for stating that these "brushless DC motors" are actually 3-phase motors (synchronous 3-phase specifically). I'm both an RC pilot and an electrical engineer so the "DC motor" false identification has always sort of annoyed me. I speculate that half of the hobbyists don't know and care. But the other half wants to learn and understand. Giving them the accurate information reduces confusion . Thank you 👍
Do you have an efficient method of testing esc's to find a bad one? For example on a quadcopter if a esc is cutting out on the left side how do you go about discovering which is the bad one?
Not really, I normally swap the motors round with the suspect ESC to see if the problem stays with the ESC or moves with the motor but after that it's a firmware update to it and re-do the throttle calibration, if it's still not happy then I'll swap it out. Best of luck!
Another great video and your channel is my first stop for technical information on RC! Hopefully you can help me with this? If you use ESCs without BECs what would be the best way to set up a 5 volt power supply?
Peter Arnold To see more videos on RC power systems visit - ruclips.net/user/playlist?list... You need to use a separate UBEC to power the board. Some now come fitted to the power distribution boards for simplicity. Happy flying!
Painless360 Thanks for your help. I have also been looking around for a 40A BLHeli ESC and there doesn't seem to be many around but found this one www.banggood.com/EMAX-BLHeli-Series-40A-50A-60A-80A-UBEC-ESC-p-963632.html. My concern is that the price for this one and other similar ones are suspiciously low? Is price something to be concerned about?
Lower process can certainly mean lower quality but getting them from the manufacturers via a middleman can still get you great technology for the lower price. Personally I'd give them a try..
Hi there , after hitting an airgate this weekend my motor no2 won't arm , I have Afro mini 20a esc . I noticed that the one in question is flashing red . I've tried to recalibrate the esc's in cleanflight and now they have all started to behave erratic and won't spin up until approx 1600 rpm . Is it the esc that's shot or motor .... ? Many thanks
Impossible to say without some more testing. I'd be tempted to swap the motor with a working on and see If the problem follows the motor or stays with the suspect ESC.. Best of luck!
+Kitsuné Blade Not if it's a brushless motor. If it's only got two wires then it's a brushed motor and will use a different type of ESC.. best of luck!
I just saw your channel and found some really helpfull informatin to build my first quadcopter. Question: I will use a 3S battery so this will give me 11.1V, BUT I have 4 motors, does this mean I have to divide 11.1V by 4, so one motor only gets 2.75V?
That was very helpful. Thanks. Quick question in case you have time... Is receiver required to start the motor with esc? I was planning to build a non RC flying object..using arduino and distance sensors and some time logic.. I saw in some other video that motor will not start if throttle not at 0. Thanks again..
Cnite Vedi No, you need to look for the PWM libraries ofr Arduino and watch my videos on ESCs on the channel to see how they work. Normally an ESC will only 'arm' once it sees a low enough PWM value that corresponds to zero throttle (usually around the 990-1050 microseconds)Best of luck.
Hi. It is possible to use racer ESC to run big motors like an Emax MT3515 650kv? There are some big ESC that are 40 amps and this little ones that have 40 amps too but in a tiny and weightless formfactor, can I run them without any damage with those big motors? I try to find this on internet but never find something. Thank you!
Great video! I was thinking on using an ESC to control a cordless drill motor, but this motors only have 2 cables, what can I do? Do I just ignore one cable and use the remaining ones?
I became a dronemaniac about a year ago and, being a technicaly skilled engineer, I am surprised that every time I watch one of your videos, I learn something new and important! I have to admit...you replaced Netflix on my tablet when I go to bed! Great job and I am watching all and every one you post...often several times!
Glad the videos are proving helpful! Best of luck with the build!
@@Painless360 hi. I screwed up my ESC of no name by wrong calibration with my tx16s radio as I was not aware of the tones. Is there any universal way of returning the single ESC 30Amp to the original setting (factory reset) somehow? How?
I have returned to RC (20 years of building/flying/crashing planes) after a 10 year lull and have explored multirotors. I have spent a pile of cash teaching myself how to build and crash but have managed to learn basic FPV. Your You Tube video channel is like the University of Modern Radio Control and should be a must for all old timers re-entering the hobby. Thanks so much for all you have taught me!
petwog You are very welcome, you are one of the audiences that this is made for.
Happy flying, welcome back!
@@Painless360 can we use this ESC for RC car
Your channel is one of the greatest ones of them all. Very in depth, yet broken down for simple minded folk such as myself. You're a great teacher!
THANK YOU SO MUCH!!!! I had a Blackfoot about four hundred years ago and am wanting to get back into the hobby with rock crawling. This stuff is all new to me and easy to understand videos like yours are a life saver. Thank you so much!
Forgot to mention, I started the build of a Hexacopter which I design for high payload and precision flying. Needless to say, your contribution to my project is incredible...I think I will print a small sticker with your logo and stick it some where on the final chef-d'oeuvre!
Learned a bunch. Thanks! Putting together an FMS PT-17 and know almost nothing about today's RC radio tech, especially electric powered, so trying to get up to speed. Used to love flying gas/nitro planes using now-extinct FM radios. Was always worried someone would accidentally turn on 'my' channel 42 and crash my beloved plane. Glad that old tech finally slithered into the tar pits. Gotta say that today's RC tech is freakin' extraordinary!
Cheers from Thailand!
+Jimbo in Thailand glad it made sense. I came back I to RC just as the old tech was dying off. There are lots of basics about current technology in the 'Introduction to Remote Control" series. Happy flying!
Being a newcomer to this hobby trying to wrap your head around all the theory takes a f***ing university degree. At some point - usually around here with ESCs and BECs - smoke is coming from your brain and your hair is catching fire but you can't put it out, because your eyes are pointing in different directions. But dont worry, it's all fun and games until you realize everything you watched and read was made back in 2012 and everything's changed since. Yay!
+iMeMySelf stick with it, it'll all make sense. This video is part of a series that's designed to cover the basics and everything in the series is still relevant. Sure, they've been improvements and changes and firmware additions but the basic principles underlying everything are still exactly the same as they were 10 years ago. Best of luck with your journey in the Hobby
Thank you @Painless360 all of a sudden, everything fell in place. You were right, it's weird and I can't explain it but you were def right about going back to the basics. Then updating on progress made since that time is easy-piecy!
New to RC Flying, and this was an outstanding beginner's outlook on how ESC's work!! Thanks for taking the time to produce this.

Thanks for helping all of us newbies. All your videos are clear, to the point and without the a noxious background music present on too many.
...and, by the way, for people who grew up with 2-stroke engines and 27MHz radios, there’s a LOT to be learned...

Painless360 what do I do with the red white and black combo wire if I don’t have a port for it on my FC?
Brilliant exposition of ESC control and brushless motors, not into RC, just needed to understand how to regulate a motor - thanks
You have a great channel. I recently picked up the hobby again after a long hiatus (since teenage years). Now I will finally finish my Tamiya Gepard (with custom gearbox), together with my son! I am so much realizing how much we were in the dark back in the era before Internet and RUclips! By the way, I now work for one of the leading manufacturers of small DC drive systems, so I have a much more professional angle towards the hobby. Still a lot of fun!
Welcome back to the hobby. A lot has changed in just the last two years. It's cheaper, we have more power using LIPOs and brusless motors, the parts and models are easier to get and repair and you'll need to reach for as PC more often now than in the 'old' days. It's even more fun now! Best of luck with the model and getting back into it all. The series called 'Introduction to Remote Control' may be a little noddy for you but may act as a reminder.. :D

Yet another great video Lee.
Thank you for what you are doing for the community buddy. Without people like you, excuse my french, I would be screwed.
Thank you.
Usefull video sir! Comprehensive rundown of all important info on brushless ESC! :)
HI YOUR VIDEOS ARE GREAT .i JUST GOT INTO qUADS AND YOUR VIDEOS ARE THE BEST!
i HAVE LEARNED A LOT FROM THEM AND IAM A OLD TIMER BE VERY CLEAR AND EASY TO UNDERSTAND,
THANKS.
Mr. Lee you are a RC Guru for many of us......Thank you Sir.!!
Now I run over a topic related to the ESC, that I find interesting: What does the frequency do and what does it mean for a motor - ESC combination? Is a frequency lets say 600Hz better than 450Hz? Or is there a kind of rule - lower kV lower frequency or does it have to do with the number of poles od a brushless motor?
With a program card or with the TX the Hz is adjustable, but what is recommended for multicopter?
The frequency is the speed of updates to the ESC from the FC. Analogue servos and traditional ESCs normally update at 50hz or 50 times a second. Sounds like a lot right?
Well, in practice a 50hz rate isn't enough for more aggressive moves with faster speeds so firmware like SimonK 6x the update speed and faster response were created. The pulses to the motor are managed by the ESC to match the throttle needed.
Hope this makes sense.
Painless360 So does this mean if I have the option to choose between 490Hz and 600Hz, I should switch to 600Hz?
(asking for Hobbywing XRotor black series ESC)
Thank you.
Very very educational. Best ESC explanation. My quadcopter got lost and was found a month later upside down in a puddle of water with battery missing. I cleaned it and dried it out and checked to make sure all the motors still turned freely by hand. After installing a new battery, i tried to fly it and it lifted off and hovered at 4 ft or so as usual but as soon as I tried to move it to the left, it drifted away and wouldn’t come back. I had to run after it to stop it. Could a bad ESC cause this drifting away issue?
If it’s hovering ok then it’s unlikely. See my video on what to check if your Quadcopter drifts.. it may help..
I used 30A ESC and a 3S lipo battery in my quadcopter. After arming the motors a strange beeping sound(1 beep) was coming from the esc s and the motor did not run when I turned on throttle. What should I do? Can you help me in this case? I'm using sp racing f3 flight controller and using i-bus connection. Actually I couldn't calibrate 4 escs at a same time with i-bus connection. Do I need to calibrate esc individually?
And do I need esc calibration every time after first calibration?
Super instruction... as a newbee I find your info clear and concise and so helpful, thank you!
+Robert Mulligan thanks for the message. I am glad the videos are proving useful. Happy flying!
In this video, does the ESC has linear or switch BEC ? Thanks in advance!
These older ESCs were almost all linear as it was the cheaper way to do it.. Happy flying!
in outline to FCB (Flight controller Boadr) they esc always have 3 line cable, is Bec Output , Ground and PWM input. so how with if the ESC just have 2 line. (Bec output & Ground) no line for PWM input. can i use this or how to do, ???
Those ESCs that have no third wire are called OPTO and the two remaining wires are PWM signal and GND.. Best of luck!
Thanks for your explanation. Something im still in question about is, can you ad reverse to any ESC or do you have to get a certain one?
Most ESCs allow you to reverse, but simply swapping any two of the three wires to the motor does the same thing... Happy flying
Hello Mr. Painless360, I've got some Optio ESCs (emax 40A) and trying to understand how to setup.@18:18 you say something about an "incoming rail". What do you mean? I just cut all the red wires from the ESCs to the flight-controler and then power only one of them on the side into the flight-controller from a seperate ubec, right?
Thanks for the effort you're making with these videos, much appreciated.
thank you this is very helpful...i have quadcopter that only has two wires for each motor as they are brushed motors..the motors burn up allot ..i was wondering if there's was way to run the brushed motor in this quad with one of these speed controllers? or am i just crazy ..i'm a newb to this stuff ..i'm a mechanic too so i'm able to fix stuff..but only if i understand it ....which i don't at the moment
Not easily, brushed motors are used on the cheaper models. you dont mention the model you have but you could google for a brushless conversion kit for it.
Best of luck!
Thanks for the great video!
Any idea why I would need to calibrate every time I change batteries?
No, that shouldn't happen.. I'd check to see if others with the same ESC have had similar problems. Best of luck!
I have since bought 12v dc 0.18a brushless 2 wire fan. I bought a pwm controller to vary the speed but the fan did not even turn with the potentiometer in either position. Struggling to get any info even from suppliers. Can you advise what type of controller I need for this type of fan? Thankyou. Great videos.
Sorry, no idea. I've not seen a brushless motor in the hobby with only two wires.. Best of luck!
Thank you ! So much to learn and things are constantly changing or being updated. Nice to have some where to look to find details in layman's terms backed by real knowledge.
Does an ESC amplify the current or input current equals the output current ??? Thank you for sharing
No, check out the other videos in the introduction to remote control playlist. Best of luck!
hello, Im working on a project - if i wanted to make a homemade leaf blower... can i just run a 90mm EDF to a 22.2 lipo or do i need a 120v esc with a on and off button? thanks for any info!
Almost, an ESC needs a 'PWM' signal to know how much power to send to the motor. In addition to a switch you will also need something like a 'servo tester' that can send the signal to the ESC for you.. Best of luck!

Great video! How can I tell if an ESC is going out? My quadcopter drifts to the left and forward after flying for a bit. Also, the front left motor doesn't seem to have the brake control working . Usually if I flick the props with my finger they don't spin while connected to the esc's. The front left one now spins freely when connected to the esc.
+Jeremy Dockter It is a STORM SRD 280 v2 with storm 15A esc and 2200kv motors
+Jeremy Dockter Sounds like the settings on one of your ESCs is different. That on it's own can cause problems like you are seeing. Normally ESCs fail in a dramatic way..
Very good video again. Can you tell me why my 20amp esc operates fine with a 3s li-po battery but when trying to use a 3S li-ion the throttle starts to play up. Full throttle and speed then begins to fall and then motor violently pulses
LVC maybe? Usually needs dropping if using LiIon. See my videos on LiIon packs.. Happy flying
Hi sir i have a question i have linear 30A escs.how do i wire it up to a tcmmrc f4 flight controller..im stuck on the part where the big red wire and black wire setup and then the smaller wires signal..ground ..you said in one video about not using red wire so i took them off.can u make a video on this..thank you
I'm guessing you're not a regular viewer. If the ESCs have linear BECs then you can connect all the red power wires to the FC without a problem (normally). See my recent 'basics' video - ruclips.net/video/xPDc6r6nRTU/видео.html
The throttle setting controls what exactly in the ESC? Is it RPM? Is it voltage? What happens when the propellar spins faster than the throttle setting (lets say you have a variable pitch drone doing a dive and the upward winds make the props spin faster as gravity makes the drone accelerate pass terminal vel).? Will the motor try and slow it down?
+RoboticSolutions.TECH an electric motor is actually a constant velocity device. It will try and maintain a constant RPM irrespective of the power supplied. That's what the KV is all about it - tells you how quickly the motor will turn for the voltage applied. What the ESC is actually changing is the duty cycle of the waveform that sent to each of the motor coils in turn. The throttle signal increases the amount of 'on' vs 'off' voltage the each motor phase gets in a high frequency waveform. There are some excellent videos and articles online the explain this in a lot of detail. Best of luck
Please dont wish me luck and send me on my merry way yet. You didnt answer my question. If wind pushes my propeller to spin faster than usual at the specified throttle setting so that its RPM is way above what it normally would be, would the ESC and motor attempt to slow down the RPM? So lets say I set my throttle to only supply 1 volt and the engine is a KV1000. But I put my variable pitch quadcopter on a dive with negative pitch so the propeller now spins at 2000RPM without changing the throttle setting. What happens? Will the Engine and ESC supply negative torque to try and slow it down or will it keep pumping 1 volt in to re-enforce the 2000RPM spin? Or will it just supply no voltage at all?
I have a question pls, if I have a 20A Esc, I can supply that with a PC power supply that give me 12V and 23A?
I don't understand what you are asking. You shouldn't try and pull more than the rated amperage from an ESC..
So the wires of my motors have 2mm male bullet connectors and the wires of my esc’s (the exact same as shown on 19:16) are about double the size in diameter. And have no connectors. Is there any right way I can connect them?
I always tend to use 3mm bullet connectors else solder the wires if I can't make that work.. Best of luck!
Very interesting, thanks! there is one topic I didn't clearly hear in your video: does any ESC controller works with any brushless motor?
Pretty much, as long as the ESC is rated for more current that the maximum the motor needs. Some motors may need tweaks to the settings though (advance etc).
Hello. I'm intent on using an RC motor in a project and have a 12V power supply and a PWM all set to go. Is it possible to connect a brushless to the PWM without an ESC or is the latter a must for brushless? If so, what motor then can I just connect to a PWM in just cutting the wires and attaching it? Your diagram and animations are informative BTW 'cos I'm learning as I go with this stuff.
+James Taylor The simple answer is.. you need an esc if you are using a brushless motor. Best of luck!
ok, i'm in a bit of a conundrum.I was trying to use a brushless motor (thanks again on clearing that other question up, btw) and my intent is to use a 12v power supply connected to a PWM which is then connected to the brushless motor. This is is all for a project. Question: am I mental for thinking this will work?

Hi! Great video and great explanation!
I’m currently building a quadcopter using an APM 2.8 and maybe you could help me solve some questions I have. I have LD Power ESC’s with NO BEC’s. Does that mean that to power the APM I should leave the JP1 INSIDE to power the whole APM with the 5V the power module provides and leave the power cables from all of the ESC’s connected? In that case, will those 5V the power module provide be enough to power the whole APM or could I have voltage shortage problems, or over voltage problems coming from adding the power module voltage and the ESC voltage (with no BEC the ESC’s should not be powering the APM at all, wright?)?
Thanks in advance!
See the power video in our APM series for the answer to your question. Best of luck!
If I have an ESC with a linear BEC, do I have to connect the BEC, or can I just cover the end of the red wire with some electrical tape? I'm thinking of using the radix PDB, so I don't need BECs, so is it safe to just not connect them, or would that damage the ESC?
If it's linear then you should be able to connect all the red wires fine. See the other videos in the 'Introduction to Remote Control' series on the channel. Best of luck!
I have these Tarot 40A 2S - 6S ESC OneShot & SimonK Firmware with 5V BEC - TL2953, the specs say they are linear but you mentioned that linear are only for 4S Lipos. I have 6 of these going onto my Tarot 680 hexacopter, so now I'm a bit worried as to the suitability of these ESC,s.
They will be fine but I'd not use them to provide the 5v the flight controller and pieces need. I'd power it using a dedicated 5V BEC.. See the other videos where I cover this in the 'Introduction to Remote Control' and 'Quadcopter building for beginners' too..
many thanks, I'll take a look at your videos, my tarot build has turned out to be a bit of a nightmare, but at the same time a very interesting learning curve. Thanks again.
Thanks for the video learned a lot but I am working with a Mystery Fire dragon 80A ESC and still figuring about how to program it to go backwards and revers like a in an RC car and how to control it with a single signal wire.
+Derpy Herpy the answers for these things are usually in the documentation. If it's not then it's not supported. I'd ask the vendor the same question..
+Painless360 do you know of any ESC that has that feature of going forwards and reverse?
If not I'll probably have to work hard to program the AVR cheap on the board to have that function..
+Derpy Herpy look for those that support 3D flying. Best of luck!
Does ESC need any special programming for reverse brushless motor turn for car or boat application? If so how to do? Complicated?
Reverseable ESCs are not too tricky. See my current boat series...
This is very informative and helped me A LOT ! Thank you!
Could you also plug a battery and esc into the reciever and power the esc through the reciever?
Nope, see the other videos in the introduction to remote control playlist for more of the basics..
So I know of 3-phase motors from commercial A/C work where I swapped electric leads to change the
direction o f spinning but can you likewise change the propeller backwards to essentially do the same
thing or are the propellers notched in a way that they'll only work in 1 direction? And I imagine some manufacturers can be swapped & others have their own, "Notched Groove" to make sure the propeller
turns the right way? I'm trying to get a basic set of, "Wants/Needs" put together for my flying.
Ultimately I want one Transmitter(easiest/user friendly) & it needs to have several, "Flight Controllers"
it can support/handshake with? Once I can establish this main issue I can have any number of other
components fall into place. My mind is whipping along......
Props can't be reversed and have the same thrust and efficiency. With a very flat profile and minimum aerofoil you can design a prop that can go both ways but most can't.. Hope that helps..
@@Painless360 >> The "prop" example I was asking was not to run it in reverse But to pull it
off the shaft & remount it the opposite way. But I digress, you've helped me to unlock my

to ensure that I don't spend monies I don't have on stuff that I can't use. Thank you again
& I'll be somewhere in your vast library...… I'm glad you have one!
Have received my skyfun todaty with a 25Amp linear esc bec but i have no idea how can I use a separated batery in order to control telemetry in one side with its own Bec and the motor and throtle in the other ... do you guys have a video showing how to use 2 separated batts for tha5? Thank you ;)
Is a brushless flight esc usable in a rc car with two Motors?
Like the old wild dagger from tamiya?
Because there is only brushed dual motor Controller for cars i can find.
Hi Painless360;
ESC Opto is the same as Optio? I'm using the E300 and says 15 A Opto.
And sorry but with the Optio you have to connect just one ESC with three cables and the others ESC's with the signal? You no say it in the video.
Sorry for too much question Painless, but thank you very much.
Yep, I've heard them called Opti and Optio (optically isolated - Opt-io). ;)
Hi! I just want to know if how many esc is allowed to be fitted to a 6 channel receiver if i place 5 esc for 5 motors on the esc and only 1 servo this 5 esc won’t damage the receiver? Since esc supplies 5v power to the receiver? Thanks 🙏
You can disconnect the red 5v wire from all but one of the ESCs to be safe. See my other RC Basics videos.. Best of mine
nice video,
well i need to know some simple questions?
a brushless in market is marked as Kv( i:e; 1000Kv, 1400Kv, 2200Kv) but ESCs are marked as 'A" (like 15A, 20A, 30A, 40A etc.)
As i know always use 20% higher ESC.
SO MY SILLY QUESTION IS THAT
FOR 1000Kv brushless motor ESC required? (in A please)
FOR 1400Kv brushless motor ESC required?
FOR 2200Kv brushless motor ESC required?
and please tell me propeller for each ?
It's not silly at all, but it sounds like you are very new to the hobby. Please watch the other videos in the 'Introduction to Remote Control' series. A lot of the basics in the hobby are covered in there. KV and Amp draw have no direct correlation. Best of luck!
i have seen all of your video but din get the answer. sorry but neither in your reply. every one is making it too complicate for me. i understand simple things. i just want to know my answers because it will help me to go one step forward to my goal. i will learn by the time, and believe me i am learning, i know the roles of each and every electornics of rc plane.
OK i make it easy
i have a 1000Kv brushless motor + 30A ESC + 3 Servos + lippo 11.1V 2200mAh battery.
IS IT A COMPATABLE CONFIGURATION FOR A RC PLANE??????
IF YES THEN,
WHAT SHOULD BE THE PERFECT WEIGHT OF THE PLANE INCLUDING ALL ELECTORNICS?
AND WHAT SHOULD BE THE PROPELLER SIZE?????
please don go into too much technicality it just complicate every thing.
I can't answer the question as you don't tell me what motor it is. The KV is how fast it turns, the amp rating how many amps the motor needs. You need an ESC with a 20% higher amp rating than the motor needs. All covered here - ruclips.net/video/DraFgiDELjI/видео.html If you're still not sure then book a chargeable support call via the website. Best of luck.
fantastic sir...this is the thing i was looking for mainly the BEC part...i am usuing a 12amp simonk with BEC with cc3d open pilot and i was wondering whather i should pop out the hot wires from the remaing 3 or not...you make me to take the right choice...mine are linear...thank you :-)
Glad it helped! Happy flying!
I want to get the complete step by step procedure in setting up my Flysky FS CT6B to control a Sabertooth motor driver for 2 wheelchair motors. After I purchased the Flysky system I discovered not everything I needed to make it work was contained in the box. I became aware that I needed a separate power source for the receiver. Then I became further confused with ESCs & BECs. I'm talking about connections, current requirements, etc. My Sabertooth driver is dual 32 amps.... This all new to me.
+William Gunter all of the basics for radio control, when it relates to radio control models, are in the 'introduction to remote control' series here on the channel. This video is part of that series, hopefully the other videos will help. Best of luck
Great video. This discussion is still valuable today for beginning RC wannabees.
so do you need an esc for a brushed dc motor?
Yes. A brushed ESC...
What does the "35A" mean on the ESC. I know it means 35 amps are supplied to the motor, but how do you determine that when picking out the correct esc to buy?
You normally choose an ESC with a higher rating than the max amps a motor will draw. I usually go for one 20% higher rated. See the other videos in the Introduction to remote control playlist.. best of luck
Which way up are the 3 wires on the connection from the ESC to the Naza Mv2 main controller? My new speed controllers have Black Red and White wires to the connector. My old ESC's had Brown Red and Orange with the brown uppermost.
Yellow and white are the signal wire, Brown or Black is GND.. Best of luck!
Hi, Thanks for your kind videos, they help us alot. I have a doubt, I have gone through with various papers and found that ESCs should not run on low throttle say 50%, do u also think the same about this. As it will generate more heat. If yes? Can we calibrate our ESC at 50% throtte i.e. 1750 and then if we run it, so for us it is 50% but for ESC it should be considered as 100% throttle right?
If yes so can we use this method to run continuously.
For modern ESCs you don't have to worry about that. Happy flying
I'm a bit unclear on the OPTO ESC's. I was planning to use my OPTOs for motor only and using a separate 6V batt to power my servos etc. Do I need to use a separate BEC or can I just plug the 6V battery pack into my receiver BATT slot?
Thanks for these videos, I subscribed.
Hey man great video tutorial very easy to understand, so thanks. I'm thinking of building copter but with a difference, I want to build one with 3 lift motors and two propulsion motors. So in otherwords 3 motors in the y axis and and 2 in the x axis. I'm just getting up to speed with ESC etc and wanted to know in principal would it be possible to control this set up and how one wuld go about wiring it? All help gratefully received
+tim lazenby not sure, I've seen other development models that use a similar setup though.. Best of luck!
Love your videos. Clear and easy to understand. Very Nice work!
Great video and explains ESC very well.. congrats
+My Drone Addiction Thank you.
Wow this is so useful! Just in the middle of building a scratch build wing and having clicking noises and warm motor, using a traditional esc type. Looks like the timing is my issue?
Very possibly. Best of luck!
I have a question. I'm very new to these types of motors and speed controllers.
And it's very nice to watch this video and understand how the motor and speed controller works. I learned a lot! And I thank you!
But why is it that I can't use a standard wall plugin, to power the speed controller and the motor?
I plug it into a lipo 2 cell and it works fine.
Plug it in using a wall plug and it only gives a slight kick and then nothing.
Any help on this would be greatly appreciated!
I'd like to use the parts of a broken and older drone, to possibly use on an airplane, or glider with the speed controller and motor assist.
I tinker with arduino's, and that's what I have the motor and speed controller plugged into. An Arduino Nano.
Again, any assistance on this would be greatly appreciated!
What do you mean 'plug it into a wall'? Motors and ESC only work on a set of very specific DC voltages..
@@Painless360 Plugged into the wall using a wall wart, plugged into an ac outlet.
What is the voltage?
Or won't it work because it needs a certain amount of amperage?
A wall wart will only deliver an amp or so and a battery. An deliver 40 to 100 times that... Power it from a Lipo..
@@Painless360 That's what I thought. And it's the high amount of amperage in a lipo battery that is dangerous, right?
Because the voltage is only 7.2, but the amperage is far greater than that in a common 9 volt battery.
Thank you! I appreciate you taking the time to explain that for me!
I'm only dealing with the small amounts of electricity needed for an arduino, 5, 9, 12 volts with very little amperage.
Again, thank you!
Can I use higher amp ESC than rated motor amps? Also, curious if we can use spare AIO 4in1 ESC's for fixed wing (single/dual motors)?
Yes and it should but fixed wing ESCs expect to be used in a different way.. Best of luck
I have a Parkmaster Pro 3D plane from MPX, and I'm noticing a fairly long spool-up time of the motor when I apply direct full throttle. In the sim, and from videos I've seen on youtube... throttle response seems waay quicker. It is pretty annoying eg. for hovering the plane. My plane also makes a weird electronic noise when making small throttle adjustments at high rpm. Am I dealing with a faulty esc? Or could I be doing something else wrong? Everything works fine, I just suspect the fairly indirect throttle response is not mormal. Thanks in advance!
I'd look at what kind of ESC you have in the model and see if there is a setting for slow spin up times. ESCs designed for larger props move to the new throttle position over a small period of time to allow the mass of the blade to catch up and increase the thrust gradually. These settings can usually be altered.. Best of luck!
+Painless360 Thanks for the quick response! My ESC is (as I read it in the manual) a "MULTIcont BL 30 S-BEC speed controller".
I will look further into it, been flying a lot today and I'm getting more used to it... maybe I'm seeing ghosts afterall. Thanks for your info, I subscribed to your fantastic channel too :)
good lecture for beginner, like me. Thank you very much
Hello,
My question is if I am running 4 ECS without BEC then my options are to either get a 5V regulator or buy 1 additional ECS with a switch BEC and replace one of the original 4 inorder to power my Naze 32 F3 acro 6 and my X8R?
Thanks
Please watch the power video in the 'Quadcopter Building for Beginners Series' on the channel. We cover the options in there. Best of luck!
Okay I watched that video. The thing is I am using the Alien frame that has the built in PCB but doesn't have the 5V output. So I could either get a 5V regulator or switch one of my ECS with a switch BEC correct? Best bet would be to get a voltage regulator right?
I'd use a separate BEC as swapping out just one of the ESCs for something different can cause stability and calibration issues. Best of luck! (can't believe they don't provide a better PDB on a frame that expensive..)
yeah I should of went with the ZMR250. Thanks Though.
I am college student, and we are working on small team project this quarter. we planed to build a control moving platform can hold 50kg(with one 4 inch wheel). we have GForce 400kv motor, 120 ESC Brushless speed control, 8.4V battery, and 2.4ghz Radio System Transmitter. After we contected all parts, the motor only worked twice, then never work anymore. Could you tell us what's problem we might have and how to make it better? Thank you!
+ubbelohed Wu this is a little outside what we normally do here. But normal troubleshooting rules will apply. I'd check the motor driver and wiring as a first thing, then start to look at the logic and firmware on the controller. Best of luck with the project.
Great information for us newbies , thanks
Hi Lee, I'd love to have your opinion: Just finished a new quadcopter build. I'm using Hobbywing xrotor 40A Blheli32 ESCs and 935kv brushless motors, pixhawk 2.4.8. All flashed with latest firmwares.
When testing the system, 3 of the motors seems to be ok but the 4th is just jumping back and forth not getting into smooth rotation to either direction. Any idea? Settings / esc problem / motor problem (all components are new). Thanks!
Sounds like one of the three wires from that ESC to that Motor isn't working/connected. I'd check that.. Best of luck!
@@Painless360 Thanks! Will check. At any rate I've sent a short video to the seller and he'll send a replacement.
Can you do a video on testing the ESCs and motors with a multimeter to check if they are running properly
+scimitar4211 Interesting idea, what specifically caused you to ask?
+Painless360 I am in the process of building a Blackout mini h, currently I have run into some problems. When testing my motors using Cleanflight 2 of 4 ESCs let out the magic smoke and possibly ruining the motors as well. I am sure all the pros check their ESCs before soldering to the PDB and to the motors, but to us newbies we just solder on and hope for the best. Unfortunately I learned my lesson the hard way and I will be getting a multimeter to test my ESCs next time. Some of us do not know how to check for continuity on the ESCs and/or the motors (including myself) so I thought it would be a great idea for a pro like yourself to do a video on that.
Very useful vid, after a 15 break from RC planes the electronics have changed a lot, in my ignorance I’ve ended up buying a Emax SimonK esc for my model glider, will there be a problem as this is a multi rotor ESC or can I use it in my glider with no issue? Thanks for any help
It will work fine. SimonK just removes the ability to change the ESC parameters you'd normally expect to be able to change (like breaking for example)... happy flying!
Thanks very much for the prompt reply, really appreciate it. Does that mean I won’t be able to programme in engine break as it’s going on a glider with a folding prop?
Painless360 thanks very much, was just hoping there would be a easy solution. Last question, any recommendations for a decent inexpensive ESC for glider application?
Depends on the amperage you need. I use cheap HK fixed wing ESCs usually..
Together with a colleague, I am looking to drive my tank with two BLDC (outrunner) motors (one for each track). We may use an Arduino to make a "digital differential", like some of the Tamiya DMD controllers. We're still in the early stages so I'm now exploring the current state of technology of RC, which your channel is proving to be of great benefit. On my channel there is an animation of the "Cletrac" differential, which is a very nice mechanical concept, although hardly suitable for RC.
You could also use a mix inside the transmitter you are using too. Look at the videos of brushless motors on twin engine 'planes. They use differential thrust to turn. Maybe that could work mixing the throttle channel with the channel you're using to turn? Best of luck with the project!
Thanks so much for your quick replies! I did consider this and will have to dive into it deeper. A requirement is that the tank does a "neutral turn" (pirouette). In the Tamiya controller, past a certain (steering) stick position, the motors will spin in opposite directions. Earlier my tank operated with two brushed motors, two Tekin reversible ESCs on two identical up-down sticks on the transmitter. This works fine but I really like the idea of controlling it as an RC car, but with the added "neutral turn" functionality. I will be uploading a video soon on the custom gearbox I already built (more than 20 years ago) and how we'll redesign it into a "high tech integrated drive system"!
Quickly researched it... looks like any transmitter with mix functions will do the trick just fine... thanks again! I'll have to find another project for that Arduino...
With modern transmitters you can actually do lots with them that you would need a Pi/Ardunio for in the past. Best of luck with the project!
Can I connect the three wires from the motor to the ESC then from the ESC to the battery without the transmitter as I only want it to operate a hairdryer..Thanks
You'll still need something to tell the ESC how much 'throttle' is needed..
i have an sk450 had a crash and i damaged one of the escs im trying to get a better understanding of quadcopters , how they work , Can i use a afro 30 amp esc with bec on the kk 2.1.5 board? , since the kk board needs power to operate on 5 volts .
neo36w eno36w Yes you can, having all the ESCs the same helps make sure the firmware is the same on each arm. I have two playlists you may find useful - 'Introduction to RC' and 'Introduction to CC3D'. Both cover a lot of basics...Best of luck.
Hello , can I ask about the current showed on the ESC ,. what is the different between 20A, 30A , 40A?
+Lim Heng Yip Vincent it's the amount of amperage it is rated to supply. You want an ESC that can support more current than your motor needs. See pur other videos in the Introduction to RC playlist and the Quadcopter building for beginners series. Best of luck!
I connected. My xxd 30a esc with 1000kv motor then to a 11.1v battery. One of the voltage regulators started to heat and melted the heat-conducting rubber. What could cause this? Do you have to connect the three-wire signal cable to the controller board before connecting battery?
+ATT T Sounds like a short in the wiring or a fault in a component. Best of luck with it!
+Painless360 , please give me any idea. Is there any problems with syncronisation of the motors when you shortened wires between motors and esc? I made a rebuild to 210 frame from 250 (it worked perfectly for some months) and cut the wires between esc and motors to the lenght about 1,5sm and now when I use Damped light option motors randomly stops on rpm increasing ( not direct throttle, but rapid yaw or pitch input, none on roll). I have little bee 20a and dys be1806 2300kv. Tried to play with timings in blheli suite and other features like demag compensation, start force etc. nothing helps. Turn of damped light helps. But it worked and nothing changed except wires esc-motor length(((
The length of the wire shouldn't make any difference - best of luck!
+Painless360 thank you, will try to find another decision..
+Painless360 Want to share my decision - yesterday I've flashed esc's with 14.6 blheli instead of 14.4, and there is one new feature - Break on stop. I've turned it off and Damped light works now without desync. Thank you.
Hello!
You have said that Switch ESC what I use in my model, if I use four of it, I need to disconnect the *RED wire. What does it mean?
Can you explain more? or Do you have any link to work with that? or Another easy way to explain by text?
Thanks for your kind!!
I would try what you said tomorrow!
See the videos in the 'Introduction to Remote Control' series for an explanation. Best of luck!
im getting the Turnigy Multistar 20A V2 ESC With BLHeli and 4A LBEC 2-6S . im just wondering how to connect them do i need to remove the red wire from 3 of the escs and just one esc with all the wires comming from the bec ?
neo36w eno36w Find out what style of BEC they have in them and watch the video again for your answer. I would only connect all the red wires if its OPTO or linear BEC (with caution)..Best of luck with it!
Thank you for stating that these "brushless DC motors" are actually 3-phase motors (synchronous 3-phase specifically). I'm both an RC pilot and an electrical engineer so the "DC motor" false identification has always sort of annoyed me. I speculate that half of the hobbyists don't know and care. But the other half wants to learn and understand. Giving them the accurate information reduces confusion . Thank you 👍
Do you have an efficient method of testing esc's to find a bad one? For example on a quadcopter if a esc is cutting out on the left side how do you go about discovering which is the bad one?
Not really, I normally swap the motors round with the suspect ESC to see if the problem stays with the ESC or moves with the motor but after that it's a firmware update to it and re-do the throttle calibration, if it's still not happy then I'll swap it out. Best of luck!
Thanks for the reply! I've seen where guys use servo testers to test esc functions. I'll try your idea of moving the motor around. Thanks again!
Another great video and your channel is my first stop for technical information on RC! Hopefully you can help me with this? If you use ESCs without BECs what would be the best way to set up a 5 volt power supply?
Peter Arnold To see more videos on RC power systems visit - ruclips.net/user/playlist?list...
You need to use a separate UBEC to power the board. Some now come fitted to the power distribution boards for simplicity.
Happy flying!
Painless360 Thanks for your help. I have also been looking around for a 40A BLHeli ESC and there doesn't seem to be many around but found this one www.banggood.com/EMAX-BLHeli-Series-40A-50A-60A-80A-UBEC-ESC-p-963632.html.
My concern is that the price for this one and other similar ones are suspiciously low? Is price something to be concerned about?
Lower process can certainly mean lower quality but getting them from the manufacturers via a middleman can still get you great technology for the lower price.
Personally I'd give them a try..
Painless360 Thanks again for your help. I will give then a go.
Hi there , after hitting an airgate this weekend my motor no2 won't arm , I have Afro mini 20a esc . I noticed that the one in question is flashing red . I've tried to recalibrate the esc's in cleanflight and now they have all started to behave erratic and won't spin up until approx 1600 rpm . Is it the esc that's shot or motor .... ? Many thanks
Impossible to say without some more testing. I'd be tempted to swap the motor with a working on and see If the problem follows the motor or stays with the suspect ESC.. Best of luck!
Could you use 2-wire motors? (just power and ground)
+Kitsuné Blade Not if it's a brushless motor. If it's only got two wires then it's a brushed motor and will use a different type of ESC.. best of luck!
Thank you for your excellent videos and descriptions,the best videos I have seen so far on internet .regards
Thank you. Happy flying!
My ESC for an AR wing has black, red and white but schematics on Matek 405 Wing shows just 2 wires where does the third wire go?
The red wire doesn't connect to anything. See my builds. Best of luck
I just saw your channel and found some really helpfull informatin to build my first quadcopter. Question: I will use a 3S battery so this will give me 11.1V, BUT I have 4 motors, does this mean I have to divide 11.1V by 4, so one motor only gets 2.75V?
Richard Johnson Not quite. Each ESC is connected to the battery and gets the full voltage - 12.4 volts from a fully charged 3s pack..
Thanks a lot, I have got it now.
That was very helpful. Thanks. Quick question in case you have time... Is receiver required to start the motor with esc? I was planning to build a non RC flying object..using arduino and distance sensors and some time logic.. I saw in some other video that motor will not start if throttle not at 0. Thanks again..
Cnite Vedi No, you need to look for the PWM libraries ofr Arduino and watch my videos on ESCs on the channel to see how they work. Normally an ESC will only 'arm' once it sees a low enough PWM value that corresponds to zero throttle (usually around the 990-1050 microseconds)Best of luck.
Painless360 thanks for replying. I will give it a shot..
Hi. It is possible to use racer ESC to run big motors like an Emax MT3515 650kv? There are some big ESC that are 40 amps and this little ones that have 40 amps too but in a tiny and weightless formfactor, can I run them without any damage with those big motors? I try to find this on internet but never find something. Thank you!
Great video! I was thinking on using an ESC to control a cordless drill motor, but this motors only have 2 cables, what can I do? Do I just ignore one cable and use the remaining ones?
If the motor has only two wires then it's probably brushed, not brush-less... Best of luck!
Painless360 Oh ok, thanks man
