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?

love when joshua from the future comes in, hes so wise

I've seen why your smoke stopper doesn't work; 17:25 the ground wire broke. At 19:15 you can see it better.

I'm literally dealing with this exact issue with my quad right now, thank you for making this video!

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.

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.. 😊👍

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.

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!

Another brilliant video JB, these bread and butter clips are required veiwing for new FPV pilots and old FPV pilots alike. 😊

LOL where was this video a week ago when I had this exact problem? Thank goodness for the multicopter subreddit for pointing me in the right direction.

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.

1 min and 17 sec into the video and you've solved the problem as to whether it's my motor or ESC. Thank you, all I need is a new motor

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

Awesome Video !! Love the way, you explain things on your KZread 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!! 👍🏻👍🏻👍🏻😎

This is the 4th time I have a problem and less than 24 later your newest video helps me

Super useful video.. My newest drone just did something like this, so now it's time to troubleshoot. Perfect timing for this video :D Many thanks from Denmark.

Thank you for tips. I crashed my very large 10kg drone the other day, the motors are twitching. These tips will help a lot

Thanks a bunch for all the tips, Joshua! 😊 Stay safe there with your family! 🖖😊

wow that actually filled me with joy and surprise to know that the motor makes those beeps. Always thought the sound stage was a little wide to be a speaker in the FC.

The second half of this video is just pure education. And pretty important knowledge.

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

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!!!

Great Videos! Please keep more trouble shooting videos. So much is learned even outside the topic.

I have that same DeWalt screwdriver. That thing rocks, the speed of the rotation increases with the twist of a wrist pretty clever I love mine

Coincidentally I am dealing with the same problem. thank you very much JB

I just went through these steps yesterday. Glad to see i checked everything how the master does it. In my case. One motor would idle fine (props off) and rev to about 20% throttle then cut out. Props on, the motor would begin to idle then twitch out and stop. Turned out damaged/broken wire to motor and I suspect this limited the current that could be delivered.

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 so much I’m having similar issues. Great timing.

AWESOME troubleshooting video AND "BACK TO THE BANDO" T shirt!

The Vfly short saver IS the best. Thanks for recommending it.

Troubleshooting videos are high value and underappreciated

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.

Hi, can u just help mi a bit? How can I replace esc? I am begginer, and have such problems as u)

Thanks for this video. Just bought a smoke stopper too.

Always keep your guard up. I recently had a motor on a little 3D printed Cub that I built and with the prop on I noticed it seemed to be turning backwards. So with the throttle fully closed I came up with this brain fart idea that maybe I needed to reverse the throttle channel on the transmitter. Well the second I did that it instantly went to full throttle (still in the same reversed direction) and the entire nose of my model virtually exploded into a million pieces right next to me. Luckily I was uninjured but after cleaning up the mess I noticed the motor no longer worked. The wiring looked okay but it just wouldn't turn. So I bought a new motor and guess what - same thing. I bought a new ESC and still no joy. The throttle channel was in Normal (not reversed) but when trying to calibrate the ESC I noticed it was working backwards. In order to get it to calibrate I had to start with throttle lever fully closed then move it to fully open and then it worked but the throttle channel was operating reversed even though it was in normal mode. I finally had to again hot switch from normal to reverse (this time with no prop) to get everything back in sync. It had me scratching my head for about a week. Motto is - BE CAREFUL

Extremely helpful video. Thank you.

Thanks Joshua

Such good and accurate information!

you are great, i enjoyed watching this and solved my problem thanks a lot!

Just want to add in you can still get your motor tones for all motors. Had a ground short on my brand new AIO and all motors still toned so be careful because if you keep the unit armed it could send that stinky smoke from the motor or blown fet. Still researching my recent and years of these issues but recently watched this one. It will probably lead to me changing the fet or spare part pile.Thanks JB for all your time researching and assisting all the hobbiest.

Excellent!

thank you so much!!!

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

super informative

Awesome info thanks!

Thanks!

Trippy. I just went through this same diagnostic process about an hour ago. It was a bad motor 🤓

Good stuff

Can't wait to see the music video made with the 2:17 worship and2:22 tick tick tick. Awesome video as well

Joshua from the Future, saves the day again!

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.

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.

i did enjoy the video

Great video, I just have a bad motor right at the instant, it spinned about 10 seconds and than completely stopped.

4:05 looks like there may be a short or potential for one between the bolt and windings under the motor.

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.

U best. Thank.

Awesome video. I have a similar situation with a tinywhoop. I swapped the "faulty" motor and it works fine when I plug it into a different location. So that either points to a short circuit or a bad ESC. How do you go from there?

You Da Man!

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.

From the first moment i've seen the smoke stopper with the negative cable disconnected I was begging you to see it

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?

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.

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?

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

that vifly didnt die, the gnd wire just gave up lol @17:25

You have saved so many of is thousands of dollars Not to mention some serious time to problem solve

looks like @ 17:19 the xt60 ground wire is loose on the first Vifly shortsaver!

I've had pads pull off of a Vifly, check those output wires

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, 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

Funny I just asked you a question about this thanks joshua

Check the xt 60 plug from the bad vifly. I had the same issue and found out, that one side was off...

Hi, thanks for all the information. I have a Dji avatar and was upgrading to axis flying upgrade kit with new motors, everything went well but at the end the front 2 motors are unresponsive, tried swiping with back one but front still unresponsive, back works fine, any help on this on this please

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!

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

@JoshuaBardwell

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

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.

Hey Joshua. First of all, thanks for the great video! I have a problem that kinda fits the video but not exactly. I conected my newly build drone to betaflight an as wanted to test the motors, they didn't spin. When i out the motor throttle up to 1068 they all start twitching. As i out the throttle higher all of the motors stop again. What could cause this problem? Thanks in advance!

I have a crux 35 elrs and after a crash from bumping the ground in left banked turn and wiping out. Now motor 4 front left pulses spins (spin,stop,spin stop) for about a second and stops with a beep, the other motors spin speeds up with motor 4 spins. also noticed the first arm after plugging in battery it wont aim and ods show cal. To trouble shoot I plugged in a new motor and it does the same. Do you think I messed up the ese in the board?

What would it mean when the first 3 beeps always happen twice before the last two?

Think it would work with those smokestoppers that fail closed? ;-)

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.

I'm new to fpv and I noticed that you have connectors on those motors for Quick change out. what type of connectors and do you recommend this for a new beginner I mean I do know how to solder I just thought maybe this is a quick fix so I could get back out flying worth it or not?

What if you get the 3 beeps but not the last two on an AIO board? My tiny trainer just fell out of the sky lol I threw a fresh battery on and just got the first 3 beeps and nothing more. It’s the BetaFPV AIO that comes with the tiny trainer DIY kit.

I dont know if you realised, but your XT60 negative wire on the circuit breaker disconnected

Happen to me 3 times with a skyliner spun into air at full speed ,had to jump In. A bush

So I got a motor & esc that both work on a servo/esc tester but not in the model. I can put another esc & same or different motor back in model & all OK. Put the new esc back in & it twitch/click. Any ideas as this video not really help.

Hell of a prop tool there buddy

Random question. I know this is an older video but the beeps mean the same if you have bluejay and not blheli?

Ça c est un tournevis électrique américain 👌🏼😂

I had no idea the ESCs were creating the beep sounds using the motors. Is there any more info on how this occurs? Curious....

Was that a silicone tubing cut to length on the stack?

So I have a Darwin Baby Ape v2 and I crashed it in a tree and when it crashed the wires got ripped out of the motor, so I bought a new motor, and soldered it on correctly, before I plugged in a battery I checked it with a multimeter to make sure the nodes where not touching (wich non were) then I powered it on. When I armed it the motor that I had replaced started twitching along with the led. I did the test to see if I had a blown mosfet, but I suggested that I didn’t. When I boot up the drone I can feel all the beeps on the motor. I removed the motor and then tried arming it, and the led flickered still, so it is probably not the motor. What do you think I should do?

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?
