Louis Rossman would be proud of that right amount of flux you used bro 😁

[@jlarson42]

What perfect timing. I've got a new fc with a bad gyro and you put out the video I've been looking for. Got a free replacement fc on the way. They suggested trying to replacing bad gyro. Nothing to loose, happy repairing 🤓

[@douglasyoung3992]

Great video Most people would just replace the flight controller this is beyond many people including me. You have the hands of a surgeon

[@theHotpointHoodlum]

You cray man! Love the content, EVEN if I never plan on doing this!

[@creationlabsinc.189]

I have a Leica A60 microscope. Love it for micro soldering and my day job fine diamond setting. Love your content! You’ve helped me a lot!

[@mungkey]

Drainman tutorials are the best!

[@carbonEYE007]

This is a great video Drainman, you got me back in the air

[@Idontdohandles]

LOVE THIS VIDEO!! Thank you -- first time i ever removed and replaced a multi-potted circuit like a gyro. Unfortunately my attempt was not successful as in when I removed the prior gyro --- either i did it or it was already faulty (my suspicion based on the INSANE number of bad betaflight AIO boards i've been frying out lately) --- I can cleary see one tiny pad in the upper right corner is missing its tin -- ie it can't be soldered or i need to find the direct-connection for that point and skip over the circuit pot link --- i can see i've cleary re-linked all the points, kept the capacitors in place, and still no gryo --- i assumed the attempt would fail once i saw a bad pad on the bottom --- but it was worth the try just for the practice. You're a mad man using that scope lol -- i don't have one, am old and can't see crap these days --- took off my eyeglasses and pulled it off naked-eye at about 3 inches distance LOL. Thanks for the education :) This board flew twice, got strangely glitchy on the 2nd flight --- and died out on third flight just fell out the sky on me :( --- was a 3 inch toothpick on the ELRS V1 board --- these things suck honestly --- anyways was bad gyro after that probably cooked from not soldering up a capacitor on the lipo --- using xt connector so too much jolt i guess but come on guys its a 1s lipo for cripes sakes.

[@edrone_]

Great information presented very well 👍

[@wagon7052]

Great video. I was looking at Bardwell's video on the nogyro message and he basically said get a new fc if what he showed doesnt work which it didnt, i am a newbie so im not really aware of what causes such issue, the issue accured on a brand new mobula6 whoop and so i couldnt beleive that the gyro was fried, luckily it was the firmware which i had been switching around while getting used to the betaflight configurator and binding things, Thanks once again for this amazing video

[@capobreakonebreak5604]

tank you so much.. i pick other gyro from other faulty FC but they have the same socket !! it worked !! i fix my FC

[@doowutchyalikefpv6479]

You saved me my friend. Brand new build was acting up on the firmware it came with when using beta 4.3 motors jittering, and getting hot within seconds. So I flashed to different firmware, and lost my gyro. I re flashed to a legacy version of the firmware, and bang all good. Now running fine, and got my gyro back. No overheating or jitters either. Iflight beast h7 AIO by the way if others have problems. Thanks so much for the info.

[@buildtestflyrepeat9428]

I had the same problem, thanks bro

[@SummerCrowfpv]

I am running a HGLRCF722 I flashed to 4.3 rc6 was getting hot motors and twitchy behavior so I tried to flash back to 4.2.11 …boom no gyro What legacy firmware did you use? I’ve tried to load 4.1 but it still had the problem of no gyro found Personally I think 4.3 is nowhere near ready for use by anyone but the developers

[@sunsetpark_fpv]

Love my Drainman repair videos :) PS THAT SCOPE IS THE SHIZZLE BRO

[@chikenfpv7798]

THANK YOU BRO!!!!!!!!!!!!!!!!!!! I SPENT 8 HOURS FIXING MY QUAD!!!!!!!!!!!!! THANKS YOOOOOOOOOOOOOUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU

[@CallistoFPV]

just used your video to replace a faulty bmi on a Diamond elrs board, thanks!!!

[@AllinFPV]

BLAZED. Thanks for the help

[@minkorrh]

it's really advantageous to have a microscope for soldering. I've paid off my cheap Banggod one about three times with the boards I've fixed. Sometimes really frustrating but worth it to learn. I built my own heat gun from a youtube vid. Swabs, alcohol, flux....and patience. Always toss some kaptan tape over the other components you're not working on so you don't blow them away. Once those tiny caps and resistors get loose, they will move without you seeing and maybe just blow off the board if you're not careful, and then you may as well toss the board as opposed to try and figure out where they all go.

[@peeweeherman5590]

I always love the Slap Down baby!!!! Baaaam....heyyyyy pilots... you da man

[@tribefpv]

Bro the stuff you do is amazing. You look like a doctor looking in your microscope 😃👍 but for me id be up for a new FC i don't have a steady hand like you. Luv your vids bro

[@Don-EfpV]

thx

[@jamesdfpv1057]

Hi! I'm trying to do this with my mamba f405 fc but can't seem to get the gyro hot enough to desolder. What flux and heat gun are you using? Thanks!

[@renderuthis]

fixed it before 1min 40 secs did not have to listen to it all haha thqanks

[@its.me_aalina4297]

Is it possible for E010 or jury h36 ?

[@MichaelRogersJesusrules]

You ledged , its back woohoo. just rolled back the firm and bam i got me a gyro ... now lets see if that motor stops spinning for no reason when i plug in the batt: Cheers mate!!

[@justinkelch4837]

@DrainMan FPV hey I have the no gyro issue on emax mini magnum 2 quad was flying came in to land and it freaked out came down rolling over sideways I put in fresh battery and now won't arm and says no gyro on screen I will try using floor noise setting but anything else to recommend?

[@TomRumbaugh]

What if you have a gyro that shows X and Y, but no Z-axis in Betaflight 4.3? the quad just spins to the ceiling when I give it power? is it dead? or could it be some other switch or control somewhere I'm missing?

[@Happyflyhigh]

Outstanding! Love your content. I must have said wow like three times during the video. Did not know you can heat gun shit off a FC. Donar board.. totally makes sense. Couple questions. What was on the toothbrush when you washed the FC? Also, It looked like you heat around the chip to place it, how's do you know when to stop heating? Can you overheat? Subscribed and hit the bell. Looking forward to some more of your content.

[@scu-dub]

Hey drain just got the new mobula 7elrs 1s and it just freaks out when arming or in the air and my gyro 3d model in betaflight also freaks out did I get a pos flight controller? It's the new 5 in 1 x12 elrs v2.0

[@Hijo-del-Chico]

hello friend, great video. I love.. It is something that we cannot all do, because we do not have a magnifying binocular, but I imagine that any amplifier that exists today that serves as a microscope, and can be seen on the phone... but a few questions, since I don't understand English very well, especially when they speak so fast for my level...lol. the questions are... will any gyro from any other plate work? . after a small bump the board ran out of gyro therefore I lost the flight modes... another thing is, what temperature does the air heater have to reach, and what substance do you put on the chip. I don't know if you can answer me but it would be very important for me. thank you.. a greeting friend.

[@skyrotfpv]

If I ever need a heart surgeon, I will give you a call! 😃🔥

[@rightawaycarhaulers5460]

I don't know how to flash and it's too easy to flash I was in my smart audio I tried to exit and it automatically Rebooted how do I get my last program back in there can it be done off the app

[@MichaelRogersJesusrules]

Hey DrainMan, can new cheep 50$ bnf micros come with bad gyro's ? ,, i suppose they can :( and funny enough i lost a cap earlier yesterday and cant find it lol .no donor boards well maybe i do have 1 now.. Love your content and i think your awesome mate ox .much love from Sth Aussie .. mad things happen when you get into new stuff watch 50,000 hrs of KZbin and start buying stuff next minute you've spent thousands lol and still don't have goggles lmho your great love the vids thank you for sharing cant wait for my microscope i hope i dont burn the monitor, luckily i have a donor :P

[@maddercat]

I have a board that the servo's cant be activated in betaflight, and then I tried to swap to emuflight, and the servos can be activated there, but it has no gyro with any firmware I can find, it's fine in betaflight...what's up with that anyone know?

[@lake4062]

Hell ya. I didn't know Joe Rogan flew...

[@Idontdohandles]

Really in my head there's no solution for a bust pad on the board that the gyro attaches too -- its basically too small to bridge the bust pad to where it needs to go.... :( Another lost FC after less than 3 flights! Just looked -- its CLKIN PIN 1 where the pad is broken -- how can I repair that - the gyro is probably fine, just a bad pad and pin connection.

[@o3rMeNs]

Is it me or are you stoned af in this video? :P

[@rightawaycarhaulers5460]

Can I turn off the gyro

[@canisrigelm0627]

I also what the answer

[@rancorbob]

DMH!

[@rancorbob]

Also when in doubt reflash amen

[@axemanarbor]

Hey man who calibrated those eyebrows?

[@canclickphotography2625]

gyro was disable

[@user-lj6is5kn8o]

Are you up in smoke?

[@csakegysenki1930]

until 2.15 only bla bla bla like a standup comedy sorry sittdown comedy.....but I want see solution!

[@cmtetaboaco]

You talk too much
