This is actually a good introduction to testing and repairing boards! I learnt much the same from hours of Louis Rossmann livestreams, but you've condensed it down into a 25min video specifically for ESCs. Great stuff man!
I think that this is my favorite video of the year. Yes, please, lets learn about FET's! More electronic videos for guys who like to fly quads!!! This video definitely TINKLED MY PINKLE 🤣😂
"Ooo...sick move" LOL I watched this video for the hell of it, having never done an SMD transplant before. It inspired me to try replacing a missing 0402 resistor that was keeping my Tinyhawk 2 from working properly. I actually did it with a soldering iron and it worked! Pulled a resistor off a bad FC with the same resistance and bingo. I went ahead and ordered a Txinlei heat station you recommended cause using an iron for that was beeyotch! Lol. Thank you so much for your wisdom man!
What a tiny tech education and the team learning way of training is easy to follow along with and you actually feel confident in doing your own after this video #IM IMPRESSED#
nice video, you seem like a really cool personality! had a good time watching this in germany because i have a broken esc on a dji phantom 2. thanks man!
Love it!! youu teach n show, show n tell time!!, hehe. thank you mate im sure i will need to be that surgeon one day .much love bn God blesss from sth aussie outback. Peace bro
Question! I have a problem with a stuttering motor. No shorts, fets all pass but when i check the voltage 1 of the pads on the problem output show 9v. Where do i start troubleshooting this?
hey man, my quad has one motor output that does not work properly, I interchanged the motors to be sure and the problems does not come from the motors but from one output, do you know if it's the ESC ? and how to check? thx
hey drainMan I've the following problem with a 4in1 blheli S. let's say, if i give all 4 esc same signal level in BF motor tab-esc 3 has lower rpm as the other 3. i tried to switch the motor, but this didn't solve the problem. any advice what's the problem? MOSFET or fet controller?

Excellent piece of info... I am so grateful for this. I am seeing an abnormal esc behavior with my esc. Currently I can fly with my quad on 4s 650mah 80c battery. But whenever I am trying to connect a normal 3s 2200mah 30c battery the battery terminals are shorting. How I found out is I have a smoke stopper and the bulb is shorting on connecting that 3s battery. I believe it is happening because of large current flow when trying to connect that battery. Can you please help me sort this riddle.
Hola. recién compre una ESC SPEEDY BEE 55A, pero resulta que cuando conecto el cable de alimentación y mido continuidad, me pita. Y no hay ningún cable haciendo contacto por ningún lado. Lo mas extraño es.. que sin los cables, vuelvo a medir y me indica que hay un tipo de corto.. La ESC esta completamente nueva... Hice una prueba probando la continuidad en el TVS Diode y me pita.. Pero desconozco del tema.. podrías orientarme
Hello there, Excellent Video!! congrats you successfully repaired that 4in1 ESC. I just purchased a speedy Bee F4 V2 stack and the ESC motor No.4 is not working. I have installed 2 proven motors in the ESC No. 4 and none of them are spinning. I have done several tests like voltage o signal and nothing is going out of the ESC No.4. I went to the motor menu and try to make it spin but nothing is working for it, for all others 3 are spinning correctly when I start them to check the spin direction. I'm out of options here is there anything else I can do? Please let me know I will be more than happy to receive your feedback. PS: I replicated your continuity test and everything looks good. Thanks for all your help. Regards,
can you teach how to check AIO FC with a multimeter? whether it's working or not. How to troubleshoot a common problems like 5v is really 5v for RX and etc. that would really be great for a newbie like me.
Hello! I also have a problem with an erevo vxl 1/16, esc velineon 3m, it doesn't go backwards anymore, I reset everything possible, it receives the command, the red light on the esc lights up but it doesn't want to go backwards, i- I also did the test on another car. Sincerely, Octavian!
Hey man! awesome video! mine ESC stop working 2 days ago (Typhoon 32 4in1). All the fets are okay, but one of the filtration capacitor burned on. There is no short if I connect it to the battery. The power distribution to FC, Rx & Camera works well, but it does not power up the motors :( Can you advice maybe?

Hey 🤙😎 Maybe you can help me. I've have an issue on motor 4, on that position the rpm are 5000rpm lower than others when I test it in Blheli. I did a cross test with another motor. Same issue on position 4. And the quad sounds weird in the air. Should be a broken mosfet to me. What do you think 🤔?
So we must google to know which mosfet is, to know about its design? I'm confuse, dont know which pin to test, and how to know it correct or wrong to determine bad mosfet
Got a HGLRC F4 Zeus F4 FC AIO 15A BLheli_S 4 In 1 ESC with a small chip next to the arrow with a bubble on it. Ironically the AIO works but it trips the smoke stopper. I can't make out what chip it is as the writing is smudged.
Excellent, enjoyed this, I have a few defective boards I can try and repair now, I was curious why you didn’t check the caps while you were testing just in case, what temp did you run your heat gun at? , I can’t locate the liquid flux in Hong Kong so in your opinion is using typical high quality flux paste ok , thanks for sharing
Drainman, I have a Holybro Tekko32 F3 4-in-1 35a mini ESC. I tested continuity and I have no shorts. I connect using the fc passthrough to BLHeliSuite_32 and I'm able to connect, but it tells me there is no valid config on any of the esc's. I cannot flash them. Any idea what is wrong?
I just put my first quad together and I don't get any beeps when I connect a battery. I was able to bind a radio and connect with beta flight but the motors won't spin.
So what does it mean if I have no motors connected to the ESC but I have continuity between two of the motors pads? I'm pretty positive i have a bad mosfet on that particular ESC. The motor stutters when I arm and won't spin up, but I noticed if I flick the prop on that motor so the motor is spinning, and then I arm it while the motor is still spinning from the momentum of flicking the prop with my finger, the motor stays spinning and I was able to fly. It seems to me it's missing a phase. Since the dead phase can't pull the permanent magnet, it stutters. But if there is already momentum, the motor uses it's own inertia to skip past the dead phase. So the motor seems to be spinning by phase 1 which is dead, but momentum carries it to phase 2, which works, sending it to phase 3 which also works. The inertia again makes the motor bell swing past phase 1, and so on. Sound like a dead mosfet to you?
Amigo necesito una ayuda me regalaron dos esc 4en 1 pero no sé de cuántos amperes son como hago para saber sin son de de 20 o 30 o 45 amperes ayuda por favor
I have a box full of these ESCs, ten to be exact either with blown MOSFETs, blown capacitors, blown traces, or in the case of two of them completely burned up. I'm glad I switched to BLHeli and BF Not being rude, but the Flyduino and FETTEC stuff cannot hold up or they fail for no reason. For me, it was under racing conditions that caused them to mainly fail on me. Even after modifying them to be soft mounted by drilling the ESCs out, it helped in terms of not being hard mounted. But in terms of handling big power, these Flyduino and FETTEC ESCs are worthless.
Ikarus been running my two fettecs on 6s with zero problems. This ESC is only rated for 5s, people run 6s and complain when it blows up lol. Fettec gear is great don’t let him fool you
Hi mate, i tested my fets and have no problems, but the mamba esc blheli s 100 flights BTF TROUBLE CODE IS RPM FILTER, WELL THAT COULD MEAN LOADSA THINGS, THE ESC DOESNT MAKE ANY MOTOR NOISE ON PLUGGING IN, IT IS DRAWING 50AMPS ON BTFLIGHT, NOT GOOD! IT DEFINATELY THE ESC, HEATS UP TO VERY HOT STRAIGHT AWAY, NO VISUAL DAMAGE ,WHAT ELSE CAN BE DAMAGED PLEASE MUCH APPRECIATED
SICK man!!!!!!!!! i felt happy and excited for you in the end too! hahaha i just plunged my quad into the drain recently. and i think i fried the ESC.. power up with Lipo, FC is on, VTX and Radio is working. but no Escs beeping sounds... Mosfets look exactly good like this, but i'll have to get a multimeter to test for continuity.. Sad thing is i dont have extra mosfet lying around, its my first build on the Mamba F722 stack with the F50pro... i think i will have to buy a new ESC =(

Let's learn about fets drainman.
Where did u learn all this? U in Cali? I'll blaze u out sometime if so

ME 2!
@@DrainManFPV You Rock Bro!
I bought an adjustable power supply some time ago. I love it. I use it to power my drones when testing. It saves you from using your lipos.
Riveting. I could actually feel my mind expanding. Thanks for making this.
I can definitely say I learned a lot today from watching this video. Thanks a bunch
"Ooo...sick move" LOL

What a tiny tech education and the team learning way of training is easy to follow along with and you actually feel confident in doing your own after this video #IM IMPRESSED#
this is a great video man im glad i found it. Im having issues with ESC and this helped me find which mosfet was damaged!!!
Nice save! Now we want to see that same ESC in a quad 😉
REALLY enjoyed this video. Great work!
Great video, thank you for the explanation and demonstration!
glad I found this channel!
Great stuff men i know this video is a little old but the content its great bro thank you
Great video, time to dig on the dead esc's box. Thanx for this unvaluable info!
Awesome thanks for the knowledge bro man, fav part was the fan bleep LOL... keep em flying
nice video, you seem like a really cool personality! had a good time watching this in germany because i have a broken esc on a dji phantom 2. thanks man!
This is great stuff Drainman! $100 esc good as new!!
Its like you teach in a way that's too easy man I'm ready like wow ...thanx man
This has been so insightful. Thank you for the video
thankz drain i need to stat doing this to save some cash maybe
Very educational. I liked that you did not do this under a microscope where you couldn't see what was going on aside from just one mosfet at a time.
Tell me all about metal oxide semiconductor field effect transistors. Ive never attempted to swap em out before, nice job!
Amazing I’m still doubting my skill on such small things though.
You should definitely do a fet video, I've got like 10 expensive esc'$ that need fixed!
can you help me, where do you find new mosfets and what they are . i have an VS 3598AP 169J52 how to identify .. thanks
Dude just saw the motors. Gonna buy them after work yeahhh
Love it!! youu teach n show, show n tell time!!, hehe. thank you mate im sure i will need to be that surgeon one day .much love bn God blesss from sth aussie outback. Peace bro

Nice video I got some that needs repair I think I’ll give it a try thanks
What's the paste you put on the fets before the heat treatment and removal?
Question! I have a problem with a stuttering motor. No shorts, fets all pass but when i check the voltage 1 of the pads on the problem output show 9v. Where do i start troubleshooting this?
Hey bud, I couldn't find the board folder in your list of products. Any ideas on where to find it?
This is awesome Drainman 🤘thanks for this
I have the same problem but from Ground to one of the pads.... Its an iFlight 35A BlHeli ESC
hey man, my quad has one motor output that does not work properly, I interchanged the motors to be sure and the problems does not come from the motors but from one output, do you know if it's the ESC ? and how to check? thx
Wow. Thanks man.. loving your videos and way you present them. Very educational and exciting at same time. Thanks happy flying.
Very interesting and informative video. 👍🤓
Good informative video thanks for sharing with us.
Where can I learn more about UAV testing board, soldering and repairing etc?
thank you very much for this useful sharing. i love this 🔥👍
that was great one question what was the gel you using to an solder the components
Agreed, whats that lube??
hey drainMan
I've the following problem with a 4in1 blheli S.
let's say, if i give all 4 esc same signal level in BF motor tab-esc 3 has lower rpm as the other 3.

What do you think 🤔?
my multimeter doesnt have the continuity feature ..all i have is the ac/dc reader and the ohms ..is there a way to tell with any of those?...
The MOSFET chips have internal connections between the pins. You got to know which pins to test. Many of them would be shorts by design.
So we must google to know which mosfet is, to know about its design? I'm confuse, dont know which pin to test, and how to know it correct or wrong to determine bad mosfet
Good tutorial. Do you know how to test for DrMos as well?
I have followed your steps. my esc is fine. but all the ice is undetectable when i calibrate the esc using BLHeli_s. do you have any suggestions?

So you say fettec esc is also not reliable on 6s? I know kiss esc likes to burn, but fettec is supposed to be more reliable
