Faster test, just test center pins. they usually not drail, so no need to know is it P or is it N and other stuff.

That was very thorough & I appreciate you explaining it for everyone to see. I’m clueless when it comes to using a multi meter but for years have wanted to know wtf I was doing whenever I’d picked one up, instead of pretending I can figure it out on my own. Thanks

The man, the myth, the best live KZreadr there is! Thanks for this video!

Awesome... Now I know definitively that my ESC needs replacing... Awesome informative video 👍

Thank you for making it easy to understand, this is the only video I have found that explains a 8 pin mosfet.

Lol, I went into an electronic store the other week with a damaged flight controller. I showed the salesmen where the smoke was coming from and he said its a mosfet. I just agreed. Thanks now I know what a mosfet is and how to test it!

Thanks for the tutorial, I've got another new use for my multimeter now👍

Thanks that is a useful video, I usually can tell because the packaging on the Fets will blister a bit when the blue smoke leaks out.

Excelent! Thanks for sharing good info! btw, is there a simple test for motors without having to spin it and check the current created? Maybe testing for resistance of each phase...

Hey Drone Mesh. Thanks alot for making this video. I have the Diatone Mamba F405 stack 3-6s. I have had problems with a dead MOSFET and you've helped me locate it. Keep up the great work. Hairy Haggis ;)

Did you make the mosfet repair/replace video yet? I loved this video! Need the repair one now! Thanks!

Very well explained. So easy to follow. Well done!

Love it. Learned so much. Thanks for the education

Great video m8. Very informative and well done. (Contituity.. nope. Continuity).

شكراًجزيلاً على الشرح الواضح والمفيد 👋🇰🇼

Thanks for explaining! Helped me understand.

Really nice, man. Again: great tip! :)

will one bad mosfet ruin an esc? i had this issue before with the motor twitching and desyncing when i throttled up. it ended up being a broken wire on the motor winding. i could never figure out how to test an esc. now i do. thanks drone mesh!

Thanks man, lots of help, You are much appreciated

Great information. Thanks for explaining.

Just finished putting together my first quad an it went well after I've binded my receiver an setup betaflight an plug the battery in no smoke so that's good but when I arm it the motors they don't idol up but they will when I throttle up except #3 an #1 doesn't seem to be working right either when I'm in betaflight the motors all work fine with the master control I was wondering if maybe you might have an idea

This is very important which u have discussed in this video THANKS U SO MUCH .....

I'm doing that already very long time. I don't mess with burned motor rewinding though (see fishpepper's blog abot this subject) - it is beyond me now. But dead component replacing often is faster and cheaper for me instead of waiting for new ESC-s and FC-s.

great info i was thinking of getting the repair parts but they stuff changes so fast by the time it is to fix its outdated. lol i so much want them motors for my blue lady how are they to the racerstar same size

Thank you so much for the great video would you be kindly give me the link where I can buy the mosfet buy for from?

Okay, that was helpful. I learned really something today. :-D

You are absolute legend my guy

Hi do you have any videos showing how to trouble shoot and repair vtx and receivers

I just ordered some top of the line esc's that you reviewed because of the good results. I plan to use the current limiting feature to help reduce damage when the prop jams. I was wondering if you think that would help or are the MOSFET's done for if the jam duration lasts too long. Plan B, will a small aluminum heat sink help? Wondering why they aren't put on by the manufacturer. Thoughts?

@Inertia888

Жыл бұрын

I can tell you that when running these mosfets as hard as we do, a heat sink will certainly help them. I think the heat sinks don't always come with the esc for weight reduction reasons. Possibly price too, but for quads that are aiming to stay under 250g, it makes sense to not use a heat sink, since there is a high rush of air cooling the electronics during flight. So, I don't know about the limiting feature, but if weight is not an issue at your final weigh-in, a heat sink will not hurt, but is not absolutely needed.

hi man, i have tested my setup and it turns out in burning one of my motors. So my question is what could have happened? Im running Holybro Tekko32 35A single ESCs and IFlight Xing 2207 2450KV. BTW thx a lot for helping me test the ESC!

Cool . that is easy way to test for bad esc. Thanks

Hi!, I try it all but I've no continuity S-D in any Mosfet. I try with 3 motors, so is not that. I try to use the gate, to try close it but no success. Do you know any other type of test?.. thank you!!!!

Great video. Thanks

Is it still possible to save a 4 in 1 esc that was wired in wrong? I accidentally wired the vbat wire from the esc to signal 1 and burned the processor of the FC. The 4in 1 ESC does not have any physical damage but it doesnt boot up anymore.

So if I get the probes mixed up and I put the positive on the negative won't it still show continuity or not?

tks for the info... Really usefull

I have the dalrc engine. I crashed tore it down put it back together now on the bench I'm drawing 55 amp and mah are shooting up fast. Help please.

i hawe a 4in1 esc and dont get power on it if i plug the bat.the motors dont beep.any sugestions?

Hello I wondering if you can help me is there a way to test a esc can handle the battery amperage it says it can i have a 150a 6s capable esc it runs fine on 2s 3s 4s then 6s it burns up is there a way to know if it can really handle 6s.

Is there reason why you can’t just check each pin combination? Polarity shouldn’t matter as your only checking if the circuit is closed or open.

Say it with me. ContiNuity

Thanks for the video. Can you explain, why our ESCs are burning? Some of them have MOSFETs rated for much higher voltage and current than the ESC, but still they are burning. Yeah, we are pushing them hard, but still - they are rated for it. Also interesting that all fets on your ESC are burnt. I'm more used to see 1 really burnt and melted fet, and the others seem ok (or at least not melted).

If there are 2 mosfets per wire, would they be paraller? So if one of them goes bad and you measure continuity you cant know which of the 2 paraller mosfets are bad as both would beeb through even if only one goes bad?

Can you connect 1 lipo to an ESC to see if it still works

Would this apply to rc car escs?

Nice n very helpfull

great video

I think I have a bad mosfet on my brand new TattooF4S. That really sucks. Have you noticed how close they are to the motor pads? They are almost touching them! I kept thinking, "theres no way those are mosfets!"- because it looks like they are actually touching the motor pads!

Nice video

wouldn't an easier method for remembering be N = negative, P = positive. If it's an N channel then the source is negative. If it's a P channel then the source is positive?

Love vids like this, thank you for breaking it down for us noobs! 👍

Which mode is "Contintuity"? :D

Just slave in another esc ! If it works, bad esc if no work, it's something else. That's what aircraft avionics techs do....lol their box changes. If you want to fix the bad ones in a bin and order your parts and bench repair them. I mean, if you do the continuity test and esc is bad, you're going to put a new one in any way. Don't waste your time. Repairing circuit boards are for professionals. You really need to know what you're doing. I worked on aircraft components, and you need to be trained. Good video. A mosfit is just a fancy switch, basically, with multiple on and offs. One is normally off the other normally on, or open & closed. That's the N & P

Are you going to do an aomway fatshark module mod? It'd be interesting to see that.

Sir i have cheap 30A esc , its creating problem If i connect motor in it and after applied signal the motor start fluctuating with high vibration . And if i use it with other esc then it works fine . Can u please tell me how can i troubleshoot this problem

Yeah I cracked the code ;)

The first thing I always do is check the contentuity.

Mad vid @Drone Mesh. I've of this tinyurl.com/ycd44qk8 and motor 3 won't run. The Mosfet test tells me all the Mosfets are fine. I've tried another motor but same result. Continuity exists between the ground pin on the FC JST pin plug with all esc Mosfets...what should I do next? Have ordered another esc to keep going but would like to trouble shoot this seemingly flawed one and either fix or toss it. Great vids...keep them coming.

Mosfet test good but motors don't run

the Bad Mosfet is very Clean, The Good Mosfet has soldering Lead splattered all over... Okey... ..

Thanks for the video. I have a Hobbywing 4 in 1 esc with a bad Mosfet (I think) or maybe it just slid out of place due to heat or a crash. Here's a picture of it: photos.app.goo.gl/13F7uTWnF0rJ9h6P2 Mosfet I need: goo.gl/4VNe5j In order to replace it I guess I'll need to buy a rework station next (suggestions?) I'd like to test it using your method but there does not appear to be a way to test it without removing it. Do you see a method? Thanks again for the video. "I learned something new today!"

I think most people are better off buying an entirely new esc. After you pay for the mosfets, heat gun, solder paste, and the inevitable mess that will be made of the board by someone with zero experience soldering SMD components, .......just buy the ESC.
