that's funny I hit your Amazon link and bought the smoke stopper and 2 minutes later that one blew up on you... should I return it and wait for a better version?
The number of posts where the person’s motor isn’t spinning or is twitching with PROPS ON INDOORS on the multirotor subreddit the last few days has been insanely high. Now I can link this video along with telling them they’re kinda dumb for arming inside with props on with a known issue on top of it
From one genius in youtube if esc for 1 motor if died on your 4 in 1 ,you can make 3in1 and 1 , buy separate esc control and sold it direct con power of battery line, and with testing in betaflight in pc(motor testing) find a control signal cable for motor what you need. I repaired my emax hawk pro with this idea.
Dang that was helpful. Its hard to get such clear, concise information in the world of electronics for those of us without electronics degrees. Thank you.
Josh from the past, you should have done this video 5 years ago. In the past 4 years I figured out how to troubleshoot but this video makes it very easy. You've got some amazing points.. thank you so much for all your hard work
There is always a point with his amazing videos that I get lost and it's exhausting to keep up. This hobby is wonderful, but taxing at times. Thanks Joshua!
Awesome Video !! Love the way, you explain things on your RUclips channel. There is a lot of usefull information (data) on your channel. I'm from Spain (Valencia), here is 03:32 in the morning & I'm watching your video. Can't stop watching your videos. Hello to everyone !!! 😎 THANK YOU FOR SHARING YOUR KNOWLEDGE WITH US!! 👍🏻👍🏻👍🏻😎
Very good explanation. I wish I would have seen it two years ago when I started with brushless motors and ESC s. I have to learn this lesson by myself. I don't need it before with nitro motors. ;-)
Thank you so much JB I can finally just send people to this video. This is the most common question I get. haven to go back and forth with questions to fix the problem no more. Lol 🤣
Thanks for the knowledge, I really appreciate it. Hopefully it can continue to provide useful lessons for all of us. Hope you are always healthy, thank you JB, have a great day.. 😊👍
Something that often occures when testing with a smoke stopper is that it detects a short once or twice in a row and then it works as expected, it is related to the capacitor(s) which are getting charged. Another topic that would be very interesting : these last months I got into too many bad gyros (much more than before). Do you know an effective way to troubleshoot a gyro on the bench ? I had bad gyros that induced "grinding noise" from the motors, even with no props, that was easy. But I had other bad gyros which were terrible on one or 2 axis, but only a flight with BlackBox could highlight the issue. Thanks Joshua.
Wow JB I literally just got this problem, I was out flying and when I switched to the Skyeliner, exactly the same kwad you are showing I had a problem with one of the motors, I don't know yet what it is but I noticed the color in that one is more yellowish as the one in your video. Thank you for posting, I have to figure it out and I should order a new motor. Question, would this motors be affected if flying the quad with a 5s lipo?
I have a case where the ESC is burning up the rear left motor 1. so it started twitching 2. i replaced the motor 3. less than 1 fight, it flipped itself, same rear left motor become twitchy So I put both motors to an independant esc later, they twitch. indicating motor is faulty now On the bench, if i switch the front motor to the rear, it spins up normally. that is really weird.
Super annoyed.. built my first quad and ended up soldering the main batt terminals backwards and fried the fc, waited for a new fc to come, finished off the build and now 2 of the motors wont spin up properly.. My luck ive either damaged motors or also fried the esc... Sooo frustrating and a big waste of money.. I tried everything reflashing the esc, reflashing the fc, did several motor spinup tests in betaflight and still the back 2 motors randomly start and stop working.. Dont know where to look now !!
hey JB,ive found the vicky short saver to be abit too sensitive - plug the quad into your bench top power supply as that will act the same as the short saver but will also tell you how much current your drawing etc. i replaced a motor just recently and then used the short saver for first power on and it was tripping on both 1 and 2 amp, plugged it in to power supply and it was drawing just over 2 amp but wasn't anything wrong with it it was just the short saver being so sensitive
I'm going through this problem right now with my skyliner and it's driving me crazy. Actually I've had this problem for about 6 months and I've just been dealing with it
Hy josh.... Kindly to help me. My 2,5" get not hard crash. After that my motor number 2 get twitching. I re soldering and opend the motor to clean up. After that motor without props are OK. But when i put it back the prop motor number 2 get twitching again. I removed the props its no problem. How can?? Thanks
Thank you for your video, it's very detailed. However, I would still need some help. I have an SP Racing F3 with a Racerstar RS20A BLheli_S, and I can make all the motors work fine using Betaflight. The issue arises when I try to use the transmitter, as one of the motors starts spinning very fast, much faster than the other three, making it impossible to control the drone. Any ideas on what might be causing this? Thanks!
So, I don't know what is going on, but I have a tinyhawk III, and one motor is not working properly. The motor doesn't exactly twitch, at least at >3o% throttle, but it doesn't turn quickly or smoothly. I connected to BLHeli and see 4 esc's, I have tried running the CLI dump for the tinyhawk III on betaflight, I have tried bot new and old motors, and I still have the same behavior. The motors all look fine and feel fine, and I have tried moving a working one over and it still doesn't work in that ESC port. I have also tried unplugging all the other motors from the ESC and powering up the quad, and I still hear 5 beeps, So can anyone help me figure out what is wrong?
Hiii can u reply to my comment pls coz my drone motor is spinning even before I throttle it and it was giving off this burnt smell just before this happened and now it ain't flying 😢 pls tell me what the problem might be
hey bud great tutorial. I bought a KF101 to start practicing with. One motor wouldn't spin. Bought a replacement arm and still nothing. Swapped the left/right leads on the board and it works. Any idea on what's broken? Is it repairable? Thanks.
Hello Joshua, a Happy New Year! Thanks for the really helpful videos, it has really teached me alot on my fpv growth. Anyway, i have a problem with my cinewhoop i hope you can help. The motor #2 on my cinewhoop (Cine Reptile 149 with iFlight Succex Mini F4 stack) it twitches and gets warm fast (not hot), it beeps and sings the regular esc tune when i plug a battery in it. The motor in question spins normally if i spin in by hand with no mechanical resistance. Same goes when it's connected to the esc, there's no electromagnetic resistance as well. But when i plug and arm the motors, this particular motor (#2) twitches then spins. And when i apply throttle power, it stops spinning mid-power then makes a new tune by itself. Then the entire thing stops spinning and then makes that esc tune again with the motor #2 making that tune second or half behind the others... What could be the problem with it, sir?
Ho ahead and spin em up while holding it down by hand. Jim Bob will hold the J for well until the ambulance arrives to restart your SMOKER. You know the Purple headed yogurt slinger, one eyed snake, weiner, willy or any other hundreds of names. I still will laugh when someone forgets or gets comfy, such as myself. Even after being attacked by my 1st quad, an Eachine Falcon 180, "Ready to Fly". Haha that was a funny joke huh. It was rtf alright straight into my face.
Joshua I have a weird problem that I experienced last night while building my 4". One of my new 2004 motors has resistance like the one in the beginning of this video. What's weird is it spins freely like the other mounted motors when not mounted to the arm. As soon as I get it barely snug on the frame, I can feel resistance when hand spinning. The mount screws are the correct length and are nowhere near the windings (they came with the motor). When I loosen them, it spins like the other motors. I tried mounting it on different arms and the problem travels. Also note that this is happening unsoldered to the FC! It's the mount screws that seems to introduce the problem. I'm assuming with this scenario it's a defective motor unless you have other thoughts? Is there a manufacturing flaw that creates a short between 2 or more motor wires when the screws are in?
What if I’m getting all the beeps, my motor spins, and it doesn’t trip my smoke stopper, but my esc gets hot when I plug my kwad in? The motor is a little twitchy when first arming and it makes a weird noise when flying. I’ve got individual escs
If the ESC gets hot when the motor is not spinning at all, I suspect it's got a shorted FET. ruclips.net/video/NW4a3AnraVk/видео.html&ab_channel=JoshuaBardwell
Going through this same problem, but what's really weird is it's not that the motor clicks, it's that it seems to spin up (and stop) slower than the other motors. So for example, when I arm the quad and then disarm it, the suspect motor stops like a half a second slower than all the other props. Everything powers on fine, but if I attempt to take off, it immediately flips over the motor that seems to have the issue. Would this indicate the same issue do you think? I picked up a new motor, but I'll have to check the ESC like in your video Hopefully it's not the FC as that's the biggest pain in the butt to resolder lol
Ha josh I have a quad that I have a motor that will not move at all. I replaced the motor,esc,and fc and it is all new and steel wont work. I used the fettec gui for the esc and did the motor test and it will work. Do you think I have a bad fc our can it be the kiss gui with the fc ?? I have several quads with fettec and all are using the same fettec esc and fc and I have no problems with them at all.
If it spins from motor test, then you know the ESC and motor are fine, and you also know the FC is capable of telling the motor to spin. At that point, if it doesn't spin when you arm, it's a bit of a mystery. Is that what you're describing?
In theory you can replace the bell, but sometimes people think it's not worth the trouble and replace the whole motor. For example, if the motor has an E-clip instead of a screw, getting the clip off without destroying it can be difficult, and the new bell may not come with a spare, and if it does, getting it back on correctly may be difficult.
Is there a site that explains what all the different beep configs mean? Because when I hook mine up, it does the normal three and then goes crazy. It keeps repeating the same three or four notes on a upward scale. I also can't seem to get it to show up on my computer for now than 3 seconds. I've installed and checked for updates on both blheli and betaflight, I've got all the drivers installed, just not sure what I'm doing wrong. In this clip you say that you have to go in and set them to dshot, but I have to get it to register on the computer first, right? Thanks for any help in advance, I really appreciate everything you do.
The rising beeps mean it's trying to do throttle endpoint calibration. This should never happen when using Dshot. It should only happen when using older analog protocols like multishot or PWM, which you should never be using on a modern multirotor. Make sure your FC is set to Dshot, assuming you're using a multirotor.
Plot twist drone isn't broken the smoke stopper has been fkn with you the whole time 🥴 19:30 Fpv drone building is a fn worm hole. Is the escs? Is it the motors? Is it too little filtering? Is it a bad gyro, is it this is it that maaaaaaan. Fxxk. I just bought new components and do process of elimination. Replace what I can best identify as the problem and if that doesn't fix it then that part I just removed was still good put it back into the drone or good parts bin and try the next possible culprit. 😉
So I fried a motor months ago ordered a few motors and installed the motor and plugged it in and no smoke then I spun the motor up and the motor started smoking again on the new one:/ so I’m assuming it’s a fried ESC? It’s a Diatone Roma F5 Any help would be awesome!
Just for clarification I’m an electrical avionics technician so I know how to troubleshoot. He his giving you extra steps. If you have a tiny whoop doing the same a smoke stop is not required as the AIO will diengage that motor and you fall out of the sky. Sorry Josh but you need to clarify what it is per drone and cell size.
When you went to avionics tech school did they teach you how things work and why they break, or did they just give you a checklist and say here's how to diagnose it, don't worry about the rest? I want people to understand what's happening. I can make a 5 second video that says "swap the motor". There's no value in that.
@@JoshuaBardwell yes they did. Keeping a 50 million dollar aircraft flying needs more than a checklist. Which is what you made for people who don’t understand. I know that you look for the root cause and solve that or you will break something else. I do enjoy your videos. I have learnt a lot. What I’m saying is it’s per drone and depends entirely on what is connected to the FCC and the EsC also.
Hey JB, I'm not sure if you remember or not but about a week ago you showed a video of mine with a motor issue, where one motor would run for a few seconds than 'reset' in a perfectly rhythmic way... I replaced the ESC and that cured it 👍 Just wanted to let you know as it's relevant to this video.
Agreed! Even though it takes 10 minutes to completely redo a motor I don’t think most people bother, among my flying buddies, it’s just me and one other person that rewind our motors. We are the FPV nerds among the group :p I like how I can change/customize the KV and I try to be wise with my use of resources on this planet. That being said I am lazy and don’t fix them right away if I have a spare on hand, I usually collect a bunch (4-6 usually) and then I do them all at once.
Solid video. You went over everything really clearly. One thing I’ve rarely run into is having just the first 3 beeps and missing the last 2 FC beeps intermittently. 75% of the time it works and flies fine. Sometimes I don’t get the beeps. I think it’s a delay on my FC initializing and sending throttle signal in time. Only had it happen with a particular FC/ESC combo
Those motor screws look too long. There’s maybe a millimeter or two of clearance. Ideally the motor screws would be flush with the top of the mount holes. Although there seemed to be some clearance, the inbound motor screws might be touching the wires. The threads could cut through and cause a short. Watch the part of the video where you zoom in on the motor.
Turns out my twitching problem in flight was simply a de-soldered capacitor. The negative side had broken lose from the ESC negative Vbat pad. In flight the broken leg of the capacitor would tap the vbat pad and release its energy causing the twitch. Hope this helps someone. Cheers Barry
Fried an ESC on Sunday and it took one of the motor into the grave. Gonna do some rapairs this weekend. RIP P.S. Seems you did not mentioned to check the continuity between the positive and the single pads of your ESC, in my case I saw there was a short on the positive and one of the pads so if I would have connected another motor to test I would have killed another motor.
@@mikebergman1817 Yeah, I am still today seeing the cost of the repair lol. It was a Mamba 40Amps not soft mounted and died in full acceleration so maybe all the factors combined took to this point. I also have to mention that it died from the side I took the first and last hard hit back in January.
So I fried a motor months ago ordered a few motors and installed the motor and plugged it in and no smoke then I spun the motor up and the motor started smoking again on the new one:/ so I’m assuming it’s a fried ESC? It’s a Diatone Roma F5 Any help would be awesome!
Hello Joshua, can you help me ? I just bought Darwin FPV Baby Ape, when I connected receiver (ELRS EP2) and when I connected the battery (it was 2S and drone was 2-3S) it smoked. ESC's circuit (FET) smoked. I measured motor - it has much lower impedance than other 3 and when I spin it (with motor screw driver) I get 1/3 of voltage of others. Could motor cause ESC to burn ? The whole setup is stock from DarwinFPV (1104 $3 cheap motors). Could motor be bad from factory ? Or ESC ? FC+Esc's not cheap on those copters. THANKS ! Love your channel. Petr
in my case stator was unglued from the base and moved about 15 degrees forward and backward. Thar caused motor lost sync in air and quad fall from sky. Works prefectly on the ground - takeoff - crash. Well. I replaced ESC - guess - didnt worked. then at the next turn stator just ripped wires off, shorted it and burned ESC.
JB, great video. Simple troubleshooting with explanation along the way. I've always wondered how to check those hard to turn motors. Way to have Joshua from the future show the humanity and confusion troubleshooting sometimes brings. Nicely done.
any video explaining what to do when esc configurator can't read any of my motors? It was working initially but after some bet a flight changes it stopped reading them

The number of posts where the person’s motor isn’t spinning or is twitching with PROPS ON INDOORS on the multirotor subreddit the last few days has been insanely high. Now I can link this video along with telling them they’re kinda dumb for arming inside with props on with a known issue on top of it
MY SMOKE STOPPER IS FRIED TOO!!!! I WENT TO HELL AND BACK, UNTIL I WATCHED THIS VIDEO!!! Now all works, as planned....WOW! Thx Bardwell!!!
I'm literally dealing with this exact issue with my quad right now, thank you for making this video!
I think JB has a bit of the psychic going on in the community.
I too am dealing with similar issues (but further down the rabbit hole) :p
same here. spooky!
haha same. my motor went yesterday
This happen so many times, I have an issue and the next day Bardwell made a video. You gotta love him❤️
From one genius in youtube if esc for 1 motor if died on your 4 in 1 ,you can make 3in1 and 1 , buy separate esc control and sold it direct con power of battery line, and with testing in betaflight in pc(motor testing) find a control signal cable for motor what you need.

@@AvallonYo one of the few times where the saying if it's stupid but it works, it's not stupid is appropriate.
Dang that was helpful. Its hard to get such clear, concise information in the world of electronics for those of us without electronics degrees. Thank you.
Turns out LED racewires, as well as looking cool, let you see the motor beeps clearly which can be handy for this kind of troubleshooting 😁
Holy timing, another incredible wealth of knowledge shared. You are a treasure sir, if I had friends I would share every video you make.

There is a lot of usefull information (data) on your channel.
I'm from Spain (Valencia), here is 03:32 in the morning & I'm watching your video. Can't stop watching your videos.
Hello to everyone !!! 😎
THANK YOU FOR SHARING YOUR KNOWLEDGE WITH US!! 👍🏻👍🏻👍🏻😎
Joshua, the black wire from the XT60 of the smoke stopper got broken in the middle of the demonstration.
Yeah, can see it at 19:16 before the multimeter covers it up
Wow! That's great to know. I can fix that easily!
Thank you for tips. I crashed my very large 10kg drone the other day, the motors are twitching. These tips will help a lot
The second half of this video is just pure education. And pretty important knowledge.
19:17 haha you ground wire on funky board thingy to XT60 is just disconnected. Lol. Thanks for the vids btw.
Thanks a bunch for all the tips, Joshua! 😊
Stay safe there with your family! 🖖😊
From the first moment i've seen the smoke stopper with the negative cable disconnected I was begging you to see it
Very good explanation. I wish I would have seen it two years ago when I started with brushless motors and ESC s.
I have to learn this lesson by myself. I don't need it before with nitro motors. ;-)
Great Videos! Please keep more trouble shooting videos. So much is learned even outside the topic.
Troubleshooting videos are high value and underappreciated
Thanks Joshua
Thank you so much JB I can finally just send people to this video. This is the most common question I get. haven to go back and forth with questions to fix the problem no more. Lol 🤣
Thanks for the knowledge, I really appreciate it. Hopefully it can continue to provide useful lessons for all of us. Hope you are always healthy, thank you JB, have a great day.. 😊👍
I've always called the ESC beeps the "Superman" tones. They just evoke the mental image of a superhero's appearance theme for some reason.
Yes. And when you buy motors for a new build - buy one or two extras from the same batch. And, all connectors suck, especially placed on arms.
The Vfly short saver IS the best. Thanks for recommending it.
4:05 looks like there may be a short or potential for one between the bolt and windings under the motor.
Trippy. I just went through this same diagnostic process about an hour ago. It was a bad motor 🤓
I've seen why your smoke stopper doesn't work; 17:25 the ground wire broke. At 19:15 you can see it better.
Something that often occures when testing with a smoke stopper is that it detects a short once or twice in a row and then it works as expected, it is related to the capacitor(s) which are getting charged.

Not to mention some serious time to problem solve
I dont know if you realised, but your XT60 negative wire on the circuit breaker disconnected
17:32 missed opportunity to change T-shirt to "Back to the Bando 2" :)
I'm glad I have learned something today.

Excellent!

Hey Joshua, which is your electric screwdriver? Seems pretty good!
I've been thinking about getting the one from Xiaomi, but I'm not sure yet.
I think the DeWalt gyroscopic is best.
Thanks!
Funny I just asked you a question about this thanks joshua
Such good and accurate information!
I have a case where the ESC is burning up the rear left motor
1. so it started twitching
2. i replaced the motor
3. less than 1 fight, it flipped itself, same rear left motor become twitchy

Bench top power supply in my experience doesn't cut off as quickly though. It depends on the quality of your PSU I guess.

I'm going through this problem right now with my skyliner and it's driving me crazy. Actually I've had this problem for about 6 months and I've just been dealing with it

So at 15:00 your smoke stopper provided power, then didn't? That's weird timing?
The wire in the smoke stopper broke.
Ho ahead and spin em up while holding it down by hand. Jim Bob will hold the J for well until the ambulance arrives to restart your SMOKER.

What if I’m getting all the beeps, my motor spins, and it doesn’t trip my smoke stopper, but my esc gets hot when I plug my kwad in? The motor is a little twitchy when first arming and it makes a weird noise when flying. I’ve got individual escs
If the ESC gets hot when the motor is not spinning at all, I suspect it's got a shorted FET.
ruclips.net/video/NW4a3AnraVk/видео.html&ab_channel=JoshuaBardwell
Was that a silicone tubing cut to length on the stack?
Going through this same problem, but what's really weird is it's not that the motor clicks, it's that it seems to spin up (and stop) slower than the other motors. So for example, when I arm the quad and then disarm it, the suspect motor stops like a half a second slower than all the other props.
Everything powers on fine, but if I attempt to take off, it immediately flips over the motor that seems to have the issue. Would this indicate the same issue do you think? I picked up a new motor, but I'll have to check the ESC like in your video
Hopefully it's not the FC as that's the biggest pain in the butt to resolder lol
I have an issue where my motor works sometimes totally fine and then other times it won’t spin. Any ideas why that might be?
Most likely the motor or ESC is damaged, although it's hard to say without more information.
Ha josh I have a quad that I have a motor that will not move at all. I replaced the motor,esc,and fc and it is all new and steel wont work. I used the fettec gui for the esc and did the motor test and it will work. Do you think I have a bad fc our can it be the kiss gui with the fc ?? I have several quads with fettec and all are using the same fettec esc and fc and I have no problems with them at all.
If it spins from motor test, then you know the ESC and motor are fine, and you also know the FC is capable of telling the motor to spin. At that point, if it doesn't spin when you arm, it's a bit of a mystery. Is that what you're describing?
@@JoshuaBardwell yes that is it. I have never had this happen. Can it be the crossfire recever??
The receiver simply tells the FC that it should arm. It doesn't control the motors.
If a have the bell or the shaft bent what do I do? New motor?
In theory you can replace the bell, but sometimes people think it's not worth the trouble and replace the whole motor. For example, if the motor has an E-clip instead of a screw, getting the clip off without destroying it can be difficult, and the new bell may not come with a spare, and if it does, getting it back on correctly may be difficult.
Is there a site that explains what all the different beep configs mean? Because when I hook mine up, it does the normal three and then goes crazy. It keeps repeating the same three or four notes on a upward scale. I also can't seem to get it to show up on my computer for now than 3 seconds. I've installed and checked for updates on both blheli and betaflight, I've got all the drivers installed, just not sure what I'm doing wrong.
In this clip you say that you have to go in and set them to dshot, but I have to get it to register on the computer first, right?
Thanks for any help in advance, I really appreciate everything you do.
The rising beeps mean it's trying to do throttle endpoint calibration. This should never happen when using Dshot. It should only happen when using older analog protocols like multishot or PWM, which you should never be using on a modern multirotor. Make sure your FC is set to Dshot, assuming you're using a multirotor.
@@JoshuaBardwell I am, it's a quad. I'm using an AOCODA F722 mini fc, 20a Blheli_S ESC.
When you say 20A blheli_s, it makes me wonder if you're using a super old ESC that doesn't support Dshot.
Plot twist drone isn't broken the smoke stopper has been fkn with you the whole time 🥴 19:30
Fpv drone building is a fn worm hole. Is the escs? Is it the motors? Is it too little filtering? Is it a bad gyro, is it this is it that maaaaaaan. Fxxk. I just bought new components and do process of elimination. Replace what I can best identify as the problem and if that doesn't fix it then that part I just removed was still good put it back into the drone or good parts bin and try the next possible culprit. 😉
So I fried a motor months ago ordered a few motors and installed the motor and plugged it in and no smoke then I spun the motor up and the motor started smoking again on the new one:/ so I’m assuming it’s a fried ESC?
It’s a Diatone Roma F5
Any help would be awesome!
I agree.
min 2:16 of the video, issue fixed.
Can the new Betaflight version 4.3 RC6 cause problems?
I flashed 4.3 and had the wrong target board name and it caused this exact problem. Reflashed to the correct target and all is good.
@@txultra2005 did auto detect not work?
@@dnsheicke8224 it does, but I just screwed it up 😕
🤠👍
Easy way to check motor vs ESC is swap motors. Problem follows it’s the motor. You take too many steps and too much money
Just for clarification I’m an electrical avionics technician so I know how to troubleshoot. He his giving you extra steps. If you have a tiny whoop doing the same a smoke stop is not required as the AIO will diengage that motor and you fall out of the sky. Sorry Josh but you need to clarify what it is per drone and cell size.
When you went to avionics tech school did they teach you how things work and why they break, or did they just give you a checklist and say here's how to diagnose it, don't worry about the rest? I want people to understand what's happening. I can make a 5 second video that says "swap the motor". There's no value in that.
@@JoshuaBardwell yes they did. Keeping a 50 million dollar aircraft flying needs more than a checklist. Which is what you made for people who don’t understand. I know that you look for the root cause and solve that or you will break something else. I do enjoy your videos. I have learnt a lot. What I’m saying is it’s per drone and depends entirely on what is connected to the FCC and the EsC also.
Thank you for tips. I crashed my very large 10kg drone the other day, the motors are twitching. These tips will help a lot
Hey JB, I'm not sure if you remember or not but about a week ago you showed a video of mine with a motor issue, where one motor would run for a few seconds than 'reset' in a perfectly rhythmic way... I replaced the ESC and that cured it 👍
Just wanted to let you know as it's relevant to this video.
I've told you before, and I'll say it again: you have the best username! 😂🥦👍
@@SunriseWaterMedia Haha! I do remember! And thank you 😉💚
Hi, can u just help mi a bit? How can I replace esc? I am begginer, and have such problems as u)
Dude your vifly has a wire disconnected you can see one wire from the board to the xt60 has come loose. That's why it stopped working.
Next video "Motor repair/rewinding"
Would be a waste to throw that mechanically fine motor in the trash. :)
Agreed! Even though it takes 10 minutes to completely redo a motor I don’t think most people bother, among my flying buddies, it’s just me and one other person that rewind our motors. We are the FPV nerds among the group :p
I like how I can change/customize the KV and I try to be wise with my use of resources on this planet.
That being said I am lazy and don’t fix them right away if I have a spare on hand, I usually collect a bunch (4-6 usually) and then I do them all at once.
mine every once in awhile will spin up.. the rest of the time it doesn’t and sounds like it restarts by doing the final two beeps again..
Solid video. You went over everything really clearly.
One thing I’ve rarely run into is having just the first 3 beeps and missing the last 2 FC beeps intermittently. 75% of the time it works and flies fine. Sometimes I don’t get the beeps. I think it’s a delay on my FC initializing and sending throttle signal in time. Only had it happen with a particular FC/ESC combo
Another brilliant video JB, these bread and butter clips are required veiwing for new FPV pilots and old FPV pilots alike. 😊
Those motor screws look too long. There’s maybe a millimeter or two of clearance. Ideally the motor screws would be flush with the top of the mount holes. Although there seemed to be some clearance, the inbound motor screws might be touching the wires. The threads could cut through and cause a short. Watch the part of the video where you zoom in on the motor.
i did enjoy the video
Turns out my twitching problem in flight was simply a de-soldered capacitor. The negative side had broken lose from the ESC negative Vbat pad. In flight the broken leg of the capacitor would tap the vbat pad and release its energy causing the twitch. Hope this helps someone. Cheers Barry
Fried an ESC on Sunday and it took one of the motor into the grave. Gonna do some rapairs this weekend. RIP
P.S. Seems you did not mentioned to check the continuity between the positive and the single pads of your ESC, in my case I saw there was a short on the positive and one of the pads so if I would have connected another motor to test I would have killed another motor.
@@mikebergman1817 Yeah, I am still today seeing the cost of the repair lol.
It was a Mamba 40Amps not soft mounted and died in full acceleration so maybe all the factors combined took to this point. I also have to mention that it died from the side I took the first and last hard hit back in January.

That test is in the ESC troubleshooting video linked in the description.
@@ruvyfpv4398 Yeah, check for continuity but that is the ESC almost for sure
@@ruvyfpv4398 sorry dude. But your assumptions are correct.
looks like @ 17:19 the xt60 ground wire is loose on the first Vifly shortsaver!
that vifly didnt die, the gnd wire just gave up lol @17:25
Hello Joshua, can you help me ? I just bought Darwin FPV Baby Ape, when I connected receiver (ELRS EP2) and when I connected the battery (it was 2S and drone was 2-3S) it smoked. ESC's circuit (FET) smoked. I measured motor - it has much lower impedance than other 3 and when I spin it (with motor screw driver) I get 1/3 of voltage of others. Could motor cause ESC to burn ? The whole setup is stock from DarwinFPV (1104 $3 cheap motors). Could motor be bad from factory ? Or ESC ? FC+Esc's not cheap on those copters. THANKS ! Love your channel. Petr
in my case stator was unglued from the base and moved about 15 degrees forward and backward. Thar caused motor lost sync in air and quad fall from sky. Works prefectly on the ground - takeoff - crash. Well. I replaced ESC - guess - didnt worked. then at the next turn stator just ripped wires off, shorted it and burned ESC.
Can I go with rcinpower v2 2207 1857 for my 5" drone or suggest me any other motor i am from India 😇😇
Those are great motors.
JB, great video. Simple troubleshooting with explanation along the way. I've always wondered how to check those hard to turn motors. Way to have Joshua from the future show the humanity and confusion troubleshooting sometimes brings. Nicely done.
@JoshuaBardwell prowadzisz jakieś szkolenia praktyczne?
any video explaining what to do when esc configurator can't read any of my motors? It was working initially but after some bet a flight changes it stopped reading them
