FC REPAIR - RaceFlight Skitzo Edition

Got in the mail a RaceFlight Skitzo edition from Sergio Domingos. The fc got a burned out F4 MCU. I show how to replace the IC. The flashing procedure you can find on RaceFlight website in detail so I did not include that portion as it would have taken too much time.

@9:25 - this is where you know Livyu is a real master. Hand-soldering those tiny pins is amazing.

[@DiGi_FPV]

[@kumokraft]

Don't worry about your english, it's good, thanks super interesting to watch

[@MnM_FPV]

The Skitzo logo under the MCU Is really an enigma! Great tutorial! And yr ENG is perfectly fine..

[@natetrombley9488]

[@ruftime]

Your English is excellent! Just got a 858d hot air station yesterday.....so much fun! I’ve got a box of tbs hv with that blown LDO , so lots to practice on:-) Thank you!

[@slinkyfpv]

[@hulpe]

your english is just fine :) dont worry ^^ really usefull video! Keep up the good work :)

[@midoriFPV]

Awesome!

[@martinnicolas2439]

It's just like magic for me .....

[@houseofpainINKS]

I dont kniw if you are aware but when they started making microchips some of the workers decided to start doing little artwork on the micro , there is people went around picking up old electronics from garbage just to look for those chips , so the logo under the pcu must just for electricians who would be the only ones to take them apart , i that my only guess ,

[@rjredd]

subbed, loved your work.

[@FlightOneVideos]

Great Video :)

[@schimefpv]

Nice work man!

[@FlightOneVideos]

What temperature and nozzle do you use on your heat gun?

[@boomingbubba6452]

No problem with the language and impressive video! What kind of temperatures did you use on the iron and hot air?

[@LivyuFPV]

apx 400 degrees C on both :)

[@GrecoFPV]

amazing !!

[@LeeFPV.]

awesome ;)

[@toffpv]

Great vidéo. Question: if you replace with a new stm32 (not from old FC) , is it possible to connect the USB or should you program with a STLINK before?

[@LivyuFPV]

With usb, stm bootloader

[@alexanderfedorov7890]

Crafty! ;)

[@f0xvibes]

which solder paste can you recommend?

[@illusionistsam]

Hey i have a flight controller which doesn't pass through video can you make video fixing it camera is fine and everything works directly can you please help us i have 2 fc just like that and i know its an easy job but cant find the components responsible for it

[@gunslingerfourtysix]

What temp is your solder at ? Can you show us what products you use in your lab ?

[@crossfpv781]

👏👏👏👏

[@keio3033]

Any idea where you could get pieces without having an extra board?

[@DiGi_FPV]

Can we take some other version of the stm32f405 RGT6 ?

[@MDP1980]

Awesome, you English is good, hey I have a racefligh revoltosd, I crash in the salt water and turn on with USB only, can be fixed?

[@stoempie73]

Can you take a blank STM32 chip and flash it ?

[@LivyuFPV]

Yes, I did just that...

[@michaeldyer6079]

I replaced the MCU, I get the green light when I plug it in, but it won't connect if I jump the bootloader to load firmware

[@LivyuFPV]

Maybe some bad soldered pins... Or bad mcu?

[@michaeldyer6079]

@@LivyuFPV mcu was brand new, everything looks like its soldered, I'll have to go in again and look. Didn't know if there was another way to download firmware on it

[@LivyuFPV]

@@michaeldyer6079 no, bootloader and feed in Fw. Check to see if every pin is soldered and no bridges. Hopufully you did not killed the mcu with too much heat. Good luck

[@michaeldyer6079]

@@LivyuFPV thank you, would I be getting a green light if it was dead?

[@LivyuFPV]

@@michaeldyer6079 don t think so... But still you have to connect to it somehow.

[@illusionistsam]
