Hi Aaron, thank you for taking the time to make this video, I’m learning every day. My question is a little outside your video subject but I’m an electronics idiot but I’m not a dumb guy, so I’m hoping to tap your expert opinion for some advice. I’m trying to pull the rope on a lifejacket CO2 manual inflator (No, using the auto inflator is not an option) using either a servo or a solenoid with a button as the trigger on off. So, I’ve guessed the torque pull required on the rope is probably 3 to 5kg and this is a one-time use one time pull device I’m trying to build. I don’t even know if that is even possible to press a button once and get enough torque from a servo or solenoid to pull a rope? Would the servo keep spinning or would it stop after the button is released? Any advice or suggestions would be most greatly appreciated! Thank you so much!
Thanks for video. Great explanation. I'm completely new to RC cars. A friend gave me his car to play with. Needless to say I did something to it and now there is a fast red blinking light on the receiver and a faster blinking red light on the esc? No steering or throttle. I saw a loose plug from the battery and an open open port (on the receiver) and thought it should be plugged in. Next thing I saw was a little bit of smoke come out of the fan...after that car no go. Please help.
I had to thumb up the video after that first joke. Good video too. I have some broken RC cars my boss asked me to repair. Since I'm an FPV quadcopter pilot, he assumes I know all about RC everything. I'm trying to learn what ESC, motor, sensored vs non sensored works with what application. I was never into RC cars until I drove one of his that I put back together. They are a lot of fun. I have rear end gear boxes disassembled, motors with what feels like bad bearings, an ESC that draws enough amps when a motor is plugged into it that it trips the overvolt protection on my power supply. However the motor runs just fine when plugged into the car that I got running. 4 of the same cars so everything is interchangeable. RC cars is another rabbit hole I'm diving into.
Helpful video thanks! I'm wanting to convert a power wheels into RC; if I bought a RC car and took the electronics package out and hooked it to the power wheels battery and motors of the power wheels, would that in theory work? I was thinking of using a linear actuator in place of a steering servo.

52 year old newbie here. Great tutorial thank you. Question - if a brushed motor has an input voltage of 7.2V, does this mean you cannot use say a Lipo 3s battery with voltage of 11.1v with that motor, as this will blow the motor?
Basically, yes. Bigger, slower rpm brushed motors can handle more voltage, but if they're designed to run on a 6-cell 7.2v NiMH pack (that usually drops down to ~6v under load) a fully charged 12.6v 3S lipo is basically double the power. It'll be very very fast for a few moments, then overheat and die. Like most things, you can do it, but there's consequences haha.
@@HobbiesDirect Thank you. That's good to know. Are their any preferred lipo 2s batteries on the market that come with an XT60 connector, or are most brands of similar offering? Sorry for the 20 questions too!

So does the recieves get all the inputs for both the Steering servo and also the Gas/Reverse(brake)? and then sent it towards the Servo and for the gas/brake to the ESC--->Motor?
Depends on if the receiver has a built in gyro or not, and if the esc is compatible. A separate gyro will go in between the receiver and servo/esc, intercepting the signal before passing it on. Transmitter -> Receiver -> Gyro -> Servo/ESC.

Your finger on the trigger/stick gives the signal for the motor, the same way as you turning the steering gives the signalto steer. A gyro senses changes in rotation/yaw/direction, and adjusts the steering/throttle to try to keep the vehicle pointed straight.@@STRIMIX
@@HobbiesDirect yes i understand the finger trigger gives the signal.. but what the first thing to recieve tjat signal? The reciever? Then from the reciever to the esc then the esc powers the motor?
Very good, never understood kv on aircraft, (just asked the shop) With regards to cars, how does reverse work, I assume it would have to be a car specific esc, and could I use my aircraft TX and rx, would I have to(be able to) set mid throttle to get reverse?

@HobbiesDirect thanks alot. Actually now I fully understand it now after alot of research. Gonna look into using an advanced flight controller called Pixhawk.
Ok, I subscribed and such. I'm going to rewatch this tomorrow when I wake up. I built a boat and used a Duratrax car to do it. I was using original battery but (probably because the prop shaft got yucky [and NOTHING is serviceable] ) the prop stopped turning until I put an 18 volt makita drill battery in it. But I'm pretty sure I'm about to fry something or everything. QUESTION how do I run everything like servos and speed control off the 9 volt and run just the motor off of the 18 volt?
You could run some electronics with a BEC to step the voltage down, but as modern ESCs act as a passthrough for motor voltage, you can't run the motor off 18v without also sending that to the ESC. If its not rated for it, it'll pop.
Hey, i am going to up grade a rc that i have for a long time, but he is more like a toy, you know like every part is made from hard plastic, the suspension is pretty basic, the engine is really bad but his structure is just like a crawler, and i want to up grade him so do you have any tip to my case?
You missed a detail. I have a little fan im useing to cool the motor, it plugs into the reciever useing 2 pins a pos/neg. But its just 2 pins not 3, and the reciever has a 3 pin input, so which freaking 2 pins are correct? The 2 on left or the 2 on right?
Depends on the receiver, but you want positive and negative, as you don't need a signal to control the fan. On most receivers, it's the middle and right. As stated in the video, your receiver should have a little diagram on it showing what pin is what. It'll only work one way, as if you plug it into the signal pin, the circuit isn't complete and the fan won't run.
So say i want to go for a full motor set up, using that same control set up, but when i turn the wheel, say to the left itll supply more power to the right wheels, and less power to the right wheels, can i set my ESC up like this? Wanting to create a centipede like racer
You'll likely need a dual motor, dual esc setup with a radio set to function in tank steer mode. We have a video of the Dumbo RC controller being set to tank steer mode on the channel 🙂
is there such a thing as a ready to install kind of set up? rather than having to buy all the parts separately, is there some kind of electronics kit that just has everything in it ready to be set up and installed? sorry if this isnt there clear on what In trying to say, I actually dont know how to word it correctly
There's this: hobbiesdirect.com.au/Kyosho-Electronics-set-with-2.4Ghz-3ch-Transmitter-Receiver-ESC-and-Servo-82145 But as there are so many combinations or setups and not all components are compatible or suitable for all vehicles, electronics kits are rare.
Hi , a question: Spektrum DX6C ( of maybe DX5C ) is compatible with my possible future Mini-z MR04 EVO2? I also do model flying, I have a lot of Spektrum Rx for my DX8, can I use them for the DX6C ? e.g. Vince
I don't know much about rc cars, but I just got a disney store rc buggy from toy story and I was wondering if I can connect it with a "generic" control as long as it has the same frequency as this one, or do I really need to get the original?
Curious. If I wanted to run power tool batteries, Is there a step down I need for the extra voltage? Or does this automatically step down? I’m new to this. I don’t use 12v tools so I have concern for the extra voltage. I’d likely use nominal 18v batteries. I’m just considering something for my nephew that runs off of tool batteries.
You'd need a speed controller capable of running that voltage. 18v (5S) isn't very common in the rc world, so you'd need a 22.2v (6S) capable ESC. These are usually quite expensive and are associated with high-power large scale cars that usually do upwards of 50mph. If you want to use drill batteries, I think there are some cheaper toy-grade cars out there.
Very informative video, many thanks! Last time I was playing with RC cars was about 30 years ago - still remember by Picco P5 (F5) engine! I wonder if you might be able to advise - I fried the receiver on a toy car (by upgrading the battery from 7.5V to 8.4... !). The steering in the car does not have a servo but a motor. Would I be able to control / connect to this steering motor with a standard RC receiver, like the one you have in your video ? Thank you in advance! :)
It's out of the subject of this video but can it be possible to use those rc engine sound module in electric bike, so when you turn the throttle it will sound likewise? If yes then please explain the wiring. Because in rc cars that module is connected to second channel for changing its sound of engine while we rotate the throttle in the remote control.
Hyy man quick question Can a DumboRc connect to a 150R ESC receiver? Right now I bought a used 99s rock crawler and it has a motor, ESC, and servo but no battery and remote
Transmitters can usually only connect to a matched-brand receiver, unless "works with everything" is their gimmick, like RadioMaster. In this case, I'd say no :-/
Please make a video on explaining how the circuit's of transmitter and receiver of RC car works , what is the function of the electronic components used in building the circuit of transmitter and receiver of the RC car , how the transmitter circuit controls the motors on the receiver side
Would it be right to say an arduino can act as an ESC? I’d like to do some form of steer by wire simulation and I’m wondering if arduino can work as the processor to not just handle throttle and steering but to also have feedback control
I’m looking to build a remote controlled lawnmower using a power chair and it’s motors. Anyone know where I could get the information I need for what servos and electronics I’d need? I’m trying to get as much info as possible.
Maybe hit up some electronics forums? Control wise, you'd likely need two ESCs - one for each side of the chassis, and a radio system that can do tank-steer.
I want to know how they designed the Transmitter circuits that emits the control signals and how the receiver decodes it and control the directions of the wheels.
Im new to rc. Just built a tamiya grasshopper but it does move in a straight line forward. Ive adjusted the steering trim but it still does not go forward in a straight line. What can i do to fix it? Thanks
No kit, it would all be custom. But you're good at fabrication and electronics, it could definitely be done. Though it might be easier to start with another 1:18 scale RC car and just try to mount the body.
So here I am sitting, considering using my 3d printer to make a rc dumper truck from scratch. I have no idea about anything RC related and im a tiny bit above avarage in cad drawing and designing stuff to print. so this can be fun! (we all know im gonna fail misserably) All i think i know, after watching this, is that i need a battery, an esc, motor to drive the wheels and 2 servos. one for steering and one for tipping the dumper. Then i guess i also need a 4 channel reciever and controller to boot? 2 channels for the servos and one for the esc/motor. But what If i want lights aswell? A light module that get put in another channel?
I got a vintage rc car and I've tried tweaking the frequency but when it get the right one or I think I do every switch in the controller only send one signal, how could I fix this? I really wanna get that car running bc besides that everything else is in great condition
Vintage crystal-based radios can be temperamental things! Your best best would be to take it to someone with experience in vintage radios, or update it to a modern 2.4GHz system.
Need some help please, iam new to RC cars. I have a brushless ftx carnage and my son tried to connect the charging cable from the battery into the visible ports of the receiver (etronix pulse 3 channel receiver). Channel 1 and 2 is used. From what I can see channel 3 which is still available is where he's tried to connect. Silly thing, it wasn't starting so he saw what looked like a male and female connection and tried connecting. There was a spark and some smoke. What has he fried? The receiver? I just bought a new battery but still not working. The car doesnt respond at all to the remote control, Appreciate any advice
Almost definitely has fried the receiver :-/ Make sure the wires to ESC haven't been damaged as well - and never plug a lipo directly into a receiver that wasn't designed specifically for that.
Haven't heard of that car, but we think the XLH 9125 is the best beginner car on the market :-) hobbiesdirect.com.au/Xinlehong-110-9125-Sprint-LWB-4WD-Electric-Off-Road-RTR-RC-Monster-Truck-9125N
I have an issue when my speed is turned up between maybe 90-100%, the car wants to reverse under light throttle. The same is true for steering. If I just barely turn right, the car will register it as turning left. Any idea wth is going on? My kids are tired of racing the neighbors' Traxxas Stampede at 80% speed 😢😆 The car is the Bezgar HB121 buggy. The radio is just about the simplest trigger and wheel style with steering trim, speed trim, aux and reverse steering options. Thanks for any info!
Not familiar with that brand or the radio that comes with it, but I'd guess the radio itself is causing the issue. Blast out both potentiometers with contact cleaner, and see if that helps :-) If not, it might just be a case of cheap electronics.
My son was given several rc cars that dont have remotes. the rear tires wont spin so its difficault for him to use these at push cars (he's 2 yrs old) is there anything i can do to remove the gears in the rear end so he can use it as a push car?
Hello, my 9125 vehicle accelerates by itself and cannot be controlled. The vehicle accelerates by itself as soon as I touch the gas trigger, I cannot control the speed in any way, it does not go behind. What could be the reason?
@@HobbiesDirect I completely disassembled the remote control and the car, cleaned and reassembled it, but it still didn't work. The gas potentiometer inside the remote control was broken. I fixed it by changing the place of the gas potentiometer with the steering wheel potentiometer. Thank you.
I am totally lost...The ESC has nowhere for the motor to plug into it at the box itself. I have to use the red and black leads (which are the same type connectors). As well if I do this, then there is nowhere to plug into the battery and the connectors on the battery are different from those on the ESC anyway. I haven't even gotten to the servo yet...I have no manuals to refer to as well. Can anyone help?
Some rc cars come with First Person View cameras, but they are usually cheaper, gimmicky things. It is always possible to mount an aftermarket camera though :-)
The radio system has almost nothing to do with the motor; it just sends a throttle position signal to your speed controller :-) FlySky gt2 is a good basic radio.
It depends greatly on the brand and model. We have a video on how to bind a FlySky GR3E, but you can check the instructions for "Binding Procedure" or "How To Bind", something like that :-)
These days the terms are used interchangeably, but to be accurate, "remote control" uses a wire to connect the controller to the device, whereas "radio control" uses a wireless connection. Just say "RC" and always be right!
Hello, I have a RC car with a crystal 5 (RX) 26.740. The controller is missing. What controller can I buy, those programmable ones that I can use with this car? The car brand is Nikko, probably a 10 year old car, but I don't want the OEM controller, I would like to buy a better quality one.
You'd very likely have to change the receiver as well; it's virtually impossible to get old rx crystals, especially ones that will work with a oem car. If the car has a combination esc/rec (likely), you'd have to swap in a new esc as well.
I am very new to the RC World. I hope that I can ask a question....I have been buying some RC vehicles and they remotes are not working. I did buy a remote control that is supposed to control vehicles. I am not finding this to be true. what remote can I buy that will control all RC's?
There isn't really one radio to rule them all, as each manufacturer uses their own programming and protocols. Radiomaster is the closest though, like this: hobbiesdirect.com.au/p/50520/radiomaster-tx16s-mk-2
@@Demolishor17 In short, the C rating is the maximum continuous current output that the battery can maintain. A 5000mAh (5Ah) with a 20C discharge rating has a theoretical output of 100 amps (5x20=100). Go as high as budget allows, but remember a lot of companies have a higher number than true for marketing purposes, so it's best to go with a reputable brand - with LiPo, you get what you pay for.

Ok, I subscribed and such. I'm going to rewatch this tomorrow when I wake up. I built a boat and used a Duratrax car to do it. I was using original battery but (probably because the prop shaft got yucky [and NOTHING is serviceable] ) the prop stopped turning until I put an 18 volt makita drill battery in it. But I'm pretty sure I'm about to fry something or everything. QUESTION how do I run everything like servos and speed control off the 9 volt and run just the motor off of the 18 volt?
You could run some electronics with a BEC to step the voltage down, but as modern ESCs act as a passthrough for motor voltage, you can't run the motor off 18v without also sending that to the ESC. If its not rated for it, it'll pop.
Extremely helpful video. Thank you
Hey, i am going to up grade a rc that i have for a long time, but he is more like a toy, you know like every part is made from hard plastic, the suspension is pretty basic, the engine is really bad but his structure is just like a crawler, and i want to up grade him so do you have any tip to my case?
Oh and, one thing that bothers me is that he don't have any ESC, servo at all so i am not sure if it would work well on him
Sounds like you'd basically be custom making everything - might be easier to just buy a crawler chassis and try to make the body fit 🙂 @@fbi4574
@@HobbiesDirect yeah i will try to buy a new one, thanks
You missed a detail. I have a little fan im useing to cool the motor, it plugs into the reciever useing 2 pins a pos/neg. But its just 2 pins not 3, and the reciever has a 3 pin input, so which freaking 2 pins are correct? The 2 on left or the 2 on right?
Depends on the receiver, but you want positive and negative, as you don't need a signal to control the fan. On most receivers, it's the middle and right. As stated in the video, your receiver should have a little diagram on it showing what pin is what. It'll only work one way, as if you plug it into the signal pin, the circuit isn't complete and the fan won't run.
Thanka for the reply.
So say i want to go for a full motor set up, using that same control set up, but when i turn the wheel, say to the left itll supply more power to the right wheels, and less power to the right wheels, can i set my ESC up like this? Wanting to create a centipede like racer
You'll likely need a dual motor, dual esc setup with a radio set to function in tank steer mode. We have a video of the Dumbo RC controller being set to tank steer mode on the channel 🙂
Very impressive video good work
Thanks! Hope it was helpful :-)
is there such a thing as a ready to install kind of set up? rather than having to buy all the parts separately, is there some kind of electronics kit that just has everything in it ready to be set up and installed?
sorry if this isnt there clear on what In trying to say, I actually dont know how to word it correctly
There's this:
hobbiesdirect.com.au/Kyosho-Electronics-set-with-2.4Ghz-3ch-Transmitter-Receiver-ESC-and-Servo-82145
But as there are so many combinations or setups and not all components are compatible or suitable for all vehicles, electronics kits are rare.
@@HobbiesDirect still, this is some thing to work from, more then I could find out my self, thanks
Hi , a question:
Spektrum DX6C ( of maybe DX5C ) is compatible with my possible future Mini-z MR04 EVO2?
I also do model flying, I have a lot of Spektrum Rx for my DX8, can I use them for the DX6C ? e.g. Vince
I don't know much about rc cars, but I just got a disney store rc buggy from toy story and I was wondering if I can connect it with a "generic" control as long as it has the same frequency as this one, or do I really need to get the original?
If you can find one with the right frequency it might work, but there's no guarantee - 27 or 40MHz is probably a good place to start.
Curious. If I wanted to run power tool batteries, Is there a step down I need for the extra voltage? Or does this automatically step down?
I’m new to this. I don’t use 12v tools so I have concern for the extra voltage. I’d likely use nominal 18v batteries.
I’m just considering something for my nephew that runs off of tool batteries.
You'd need a speed controller capable of running that voltage. 18v (5S) isn't very common in the rc world, so you'd need a 22.2v (6S) capable ESC. These are usually quite expensive and are associated with high-power large scale cars that usually do upwards of 50mph. If you want to use drill batteries, I think there are some cheaper toy-grade cars out there.
Very informative video, many thanks! Last time I was playing with RC cars was about 30 years ago - still remember by Picco P5 (F5) engine!
I wonder if you might be able to advise - I fried the receiver on a toy car (by upgrading the battery from 7.5V to 8.4... !).
The steering in the car does not have a servo but a motor. Would I be able to control / connect to this steering motor with a standard RC receiver, like the one you have in your video ? Thank you in advance! :)
You'd likely have to hack in a small hobby grade servo to make everything work, but anything is possible!
where could i get the whole sistem, but without buing an rc car?
I think I’m going to need to listen to this at half speed! 🤯
It's out of the subject of this video but can it be possible to use those rc engine sound module in electric bike, so when you turn the throttle it will sound likewise? If yes then please explain the wiring. Because in rc cars that module is connected to second channel for changing its sound of engine while we rotate the throttle in the remote control.
No idea about the wiring of an e-bike, but i assume it would be possible if you could get the sound module to read the throttle position of the bike.
thanks only man on youtube that told me what i wanted to know 🤠
The only one? Nice!
Hyy man quick question
Can a DumboRc connect to a 150R ESC receiver? Right now I bought a used 99s rock crawler and it has a motor, ESC, and servo but no battery and remote
Transmitters can usually only connect to a matched-brand receiver, unless "works with everything" is their gimmick, like RadioMaster. In this case, I'd say no :-/
@HobbiesDirect thx that's all I needed to know
Please make a video on explaining how the circuit's of transmitter and receiver of RC car works , what is the function of the electronic components used in building the circuit of transmitter and receiver of the RC car , how the transmitter circuit controls the motors on the receiver side
Good idea, hopefully in the future :-)
Would it be right to say an arduino can act as an ESC? I’d like to do some form of steer by wire simulation and I’m wondering if arduino can work as the processor to not just handle throttle and steering but to also have feedback control
I’m looking to build a remote controlled lawnmower using a power chair and it’s motors. Anyone know where I could get the information I need for what servos and electronics I’d need?
I’m trying to get as much info as possible.
Maybe hit up some electronics forums? Control wise, you'd likely need two ESCs - one for each side of the chassis, and a radio system that can do tank-steer.
GREAT ! SUCH A GREAT VİDEO AND BRIEFING ! THANKS A LOT !
I want to know how they designed the Transmitter circuits that emits the control signals and how the receiver decodes it and control the directions of the wheels.
Good question
Im new to rc. Just built a tamiya grasshopper but it does move in a straight line forward. Ive adjusted the steering trim but it still does not go forward in a straight line. What can i do to fix it? Thanks
You should try manually aligning the steering by adjusting the length of the steering tie rods.
Very well explained video, thank you I just subscribed, been looking for a good video on this topic👊💯 Thank you bro.
Do you have any good recommendations of starter kits
What do I do if I ripped my on/off switch wire on my castle creations esc?
Panic? j/k, can the wires be rejoined or can it be soldered back on?
Is there a kit to convert a Burago Dodge Viper rt/10 1;18 scale die cast into a high-speed RC?
No kit, it would all be custom. But you're good at fabrication and electronics, it could definitely be done. Though it might be easier to start with another 1:18 scale RC car and just try to mount the body.
I need help. I just bought an arrma felony 6s and it had a delay when I hit full throttle. What’s the problem? Any help will be appreciated
Might just be a calibration issue - reset all the endpoints and go from there :-)
@@HobbiesDirect thanks I will attempt that 👍
Fantastic video, thank you for this!
It's what we do!
Can toy grade rc cars be made into hobby grade if parts are available?
If parts are available, why not? Go for it :-)
So here I am sitting, considering using my 3d printer to make a rc dumper truck from scratch. I have no idea about anything RC related and im a tiny bit above avarage in cad drawing and designing stuff to print. so this can be fun! (we all know im gonna fail misserably)
All i think i know, after watching this, is that i need a battery, an esc, motor to drive the wheels and 2 servos. one for steering and one for tipping the dumper. Then i guess i also need a 4 channel reciever and controller to boot? 2 channels for the servos and one for the esc/motor. But what If i want lights aswell? A light module that get put in another channel?
Yep! RC led kits usually just get run off a spare channel in the receiver. Good luck with your project :-)
I got a vintage rc car and I've tried tweaking the frequency but when it get the right one or I think I do every switch in the controller only send one signal, how could I fix this? I really wanna get that car running bc besides that everything else is in great condition
Vintage crystal-based radios can be temperamental things! Your best best would be to take it to someone with experience in vintage radios, or update it to a modern 2.4GHz system.
Very helpful, well done..
I prefer my servos toasted with a little cheddar and bbq sauce.
You guys are hilarious.🤣

Thanks for the sub!
Need some help please, iam new to RC cars.
I have a brushless ftx carnage and my son tried to connect the charging cable from the battery into the visible ports of the receiver (etronix pulse 3 channel receiver). Channel 1 and 2 is used. From what I can see channel 3 which is still available is where he's tried to connect. Silly thing, it wasn't starting so he saw what looked like a male and female connection and tried connecting. There was a spark and some smoke. What has he fried? The receiver? I just bought a new battery but still not working. The car doesnt respond at all to the remote control, Appreciate any advice
Almost definitely has fried the receiver :-/ Make sure the wires to ESC haven't been damaged as well - and never plug a lipo directly into a receiver that wasn't designed specifically for that.
Do you think it's possible to do a full tuto on how to build one from scratch ?
Any recomendation set to start with , I ve Reely Model 12811b ,is it good to start with ? can i buy this set to start with ?
Haven't heard of that car, but we think the XLH 9125 is the best beginner car on the market :-)
hobbiesdirect.com.au/Xinlehong-110-9125-Sprint-LWB-4WD-Electric-Off-Road-RTR-RC-Monster-Truck-9125N
I have an issue when my speed is turned up between maybe 90-100%, the car wants to reverse under light throttle. The same is true for steering. If I just barely turn right, the car will register it as turning left.
Any idea wth is going on? My kids are tired of racing the neighbors' Traxxas Stampede at 80% speed 😢😆
The car is the Bezgar HB121 buggy. The radio is just about the simplest trigger and wheel style with steering trim, speed trim, aux and reverse steering options.
Thanks for any info!
Not familiar with that brand or the radio that comes with it, but I'd guess the radio itself is causing the issue. Blast out both potentiometers with contact cleaner, and see if that helps :-) If not, it might just be a case of cheap electronics.
@@HobbiesDirect will do! My bet is that you are correct in either case lol
where can i buy this parts?? what the of every part in aliexpress?? thanks
Does servo makes your rc car faster?
My son was given several rc cars that dont have remotes. the rear tires wont spin so its difficault for him to use these at push cars (he's 2 yrs old) is there anything i can do to remove the gears in the rear end so he can use it as a push car?
Just like you said - if you take the gears out of the gearbox, the car should freewheel :-)
Can this knowledge apply to RC plane or is there a difference?
Hello, my 9125 vehicle accelerates by itself and cannot be controlled. The vehicle accelerates by itself as soon as I touch the gas trigger, I cannot control the speed in any way, it does not go behind.
What could be the reason?
First thing to check would be the controller itself - try blasting out the trigger potentiometer with compressed air and contact cleaner :-)
@@HobbiesDirect I completely disassembled the remote control and the car, cleaned and reassembled it, but it still didn't work. The gas potentiometer inside the remote control was broken. I fixed it by changing the place of the gas potentiometer with the steering wheel potentiometer. Thank you.
@@lyc3d2 Nice! Well done 🙂
I am totally lost...The ESC has nowhere for the motor to plug into it at the box itself. I have to use the red and black leads (which are the same type connectors). As well if I do this, then there is nowhere to plug into the battery and the connectors on the battery are different from those on the ESC anyway. I haven't even gotten to the servo yet...I have no manuals to refer to as well. Can anyone help?
What ESC from what brand are you referring to?
🎉where can l find those components
Links in the description :-)
Can someone answer me please, i had seen rc cars with cameras. are they giving camera with these cars
Some rc cars come with First Person View cameras, but they are usually cheaper, gimmicky things. It is always possible to mount an aftermarket camera though :-)
@@HobbiesDirect thanks
Recommend transmitter and receiver for 60volt motor
The radio system has almost nothing to do with the motor; it just sends a throttle position signal to your speed controller :-) FlySky gt2 is a good basic radio.
How do I connect the remote control to the car?
It depends greatly on the brand and model. We have a video on how to bind a FlySky GR3E, but you can check the instructions for "Binding Procedure" or "How To Bind", something like that :-)
i didnt quite understand how a proportional steering system works can anyone explain to me?
Nice video make more videos like this explanation.
Great work bro
Thanks!
Is a remote control rc & a radio controlled rc the same thing??
These days the terms are used interchangeably, but to be accurate, "remote control" uses a wire to connect the controller to the device, whereas "radio control" uses a wireless connection. Just say "RC" and always be right!
@HobbiesDirect cool, thank you
Great video. Thank you for this. It has erased some of my ignorance. Not your fault I have an awful lot of it.

Hello, I have a RC car with a crystal 5 (RX) 26.740. The controller is missing. What controller can I buy, those programmable ones that I can use with this car? The car brand is Nikko, probably a 10 year old car, but I don't want the OEM controller, I would like to buy a better quality one.
You'd very likely have to change the receiver as well; it's virtually impossible to get old rx crystals, especially ones that will work with a oem car. If the car has a combination esc/rec (likely), you'd have to swap in a new esc as well.
got a brushed motor with 12t going to put a 11.1v 5000mah lipu battery in it is that too much?
In short - yes. That motor will get super hot and burn out quite rapidly. It'll be very fast for the 3 minutes it will run though 🙂
I am very new to the RC World. I hope that I can ask a question....I have been buying some RC vehicles and they remotes are not working. I did buy a remote control that is supposed to control vehicles. I am not finding this to be true.
what remote can I buy that will control all RC's?
There isn't really one radio to rule them all, as each manufacturer uses their own programming and protocols. Radiomaster is the closest though, like this: hobbiesdirect.com.au/p/50520/radiomaster-tx16s-mk-2
Love your video very informative. Simple to understand for me lol at my age💪😅.. Ty again will be watching your stuff very good🙏💪💪
how about the high rate discharge?
What about it?
@@HobbiesDirect I mean, the "C" rating
@@Demolishor17 In short, the C rating is the maximum continuous current output that the battery can maintain. A 5000mAh (5Ah) with a 20C discharge rating has a theoretical output of 100 amps (5x20=100). Go as high as budget allows, but remember a lot of companies have a higher number than true for marketing purposes, so it's best to go with a reputable brand - with LiPo, you get what you pay for.
Hey guys, I have a Arrma Felony. Anyone know a good drag set up for it. And a good 8s combo
Have you ever used a graphene battery?
My rc car is working but not moving fwd . In controller can see the led getting lit but rc not moving, no notice of motor running
If all the connections are secure, might be time for a new motor :-/ If you have a voltmeter, you can check the output of the ESC to the motor wires.
I actually learned by myself by taking it appart my rc crawler 😅😅 it was a mess with parts everywhere on the floor
This is the way!
