I love these videos because they give me hope I can one day take a broken flight controller and fly it again instead of just buying a new one. So enlightening to see how the steps for this replacement isn't so complicated. Just takes a little practice. Thanks for posting it!
It's amazing, when I first came into the quad world, soldering everything together seemed like a daunting task, almost impossible. I used to be nervous about something as simple as switching a motor, now I dont have a single worry about swapping motors and escs and such, but your videos are de-mistifying the process of electronic repairs!
Hello, I have a Maketsys F405 CTR flight controller and I need a 3.3v voltage regulator but I can't find it, the code here is L314, which regulator could I put in its place?
I have a Crazybee f4 lite 1s FC, and one ESC is still beeping when turning on, but when asming the motor doesn't rotate properly. It's twitching, as if it cannot find the right rythm. I tested with other motors, but the problem is the ESC. Do you have any idea what I could do?
I know it s an old video but anyway if you reply, I ll be happy so.... 11min46 you replaced the mosfet and I notice that 2 legs on top are shorted and later in the video they are not anymore. Did you noticed that also and cleaned it or it stayed like that? I m learning a lot from you and because of you I start to repair my stuffs. it works mate it works. Thank you so much Livyu.
Hello Liviu, im having similar issue with a BETAFPV 1-2S AIO board. I sended u message. All i wanted to know is: one of 4 esc's burned by accidentaly shorting 2 motor wires. It still worked, but motor had no "force" and was not spinning like others, and the quad wont lift off. I tryed to change the mosfet with burn mark, but still the same... I wanted to know if i have to change the whole mosfets or is there a way to know what to replace... If u have time ill send u some pics by messenger. Thanks for your work !! 👌💪
I have the same FC (though it’s the Racerstar branded one) and my 5V to the FC and esc is bad. I can connect it to BF and everything looks fine. Which is the 5V regulator.
capacitors in series does not add capacitance, divides it. Are you sure those capacitors are in series? It also raises the internal resistance. Caps in parallel adds capacitance and lowers IR. nice video man. I blew my esc up, unloaded motor and sudden stop from high Rpm, killed mosfet after mosfet, probably needs a cap mod or something if banggood sends me a new one.
I had a tekko-s 4in1 that was working perfectly then all of a sudden just dropped out the sky. Now when i power it all the video,fc,rc etc get powered but the escs dont respond or get any signal from the motors so no beeps upon powering them and no communication in betaflight or bliheli. Normally I have had 1 esc go bad on a 4in1 but never just a complete there all fucked no response. If i knew what component was dead i could try and replace it :) ''try''.
Livyu FPV thanks for your time...i also have revolt v2...i flashed it from flight one to betaflight 3.4 it successfully flashed but after a few reboots it was not boting up..the data/status led is not flashing...but the board has power
normal gyros are not bga's so no reballing needed. But yes i have changed in the past gyros never did a video about it cause i had no fc's with that issues. If someone sends one i will most definitely do it :)
The kiss fc v2 firmware is closed source and I said i cannot show you guys hot to do it. Sorry but kiss is a closed source firmware... But I guess you knew this. No hacks
So after hearing what you said in this video. You must really be hating this toothpick craze. Because there's all sorts of All-In-Ones right now. This must be like some kind of weird self manifesting dystopian future for you huh? 😁😂😂😉

Omg!! Thank you!!! You help me learn to fix a bad mosfet on 1s AIO. Got tons of unuseable fc due to esc problem and your video really helped!!!!!

Another fun and exciting journey into the world of diagnostic testing and repair. Job well done mate. 🤘😎
always nice to see your repair vids
This is the 2nd awesome video I've watched on your site - great work - I'm subscribed now!
Hi dude 😊 thanks for that video! Just a question, how can i find the right or similar mosfet for the esc board? There is a serial number? Thanks a lot
Hello, I have a Maketsys F405 CTR flight controller and I need a 3.3v voltage regulator but I can't find it, the code here is L314, which regulator could I put in its place?
Would you please share the link of the soldering flux that you use or recommend?

Hello friend, what temp you use for this mosfet replacement?
I know it s an old video but anyway if you reply, I ll be happy so.... 11min46 you replaced the mosfet and I notice that 2 legs on top are shorted and later in the video they are not anymore. Did you noticed that also and cleaned it or it stayed like that?

Very nice! I learned something today! Can you tell me what your rework station is? Also what are you using for solder paste? Thanks. Very helpful.
Hi..my 4 in 1 esc 35A didn't not beep at all when battery plugged and what does problem?
What size are those ceramic caps? I dont have the tools to measure and I just need to replace one. Thanks!
Are you using a microscope to do this you made it look so easy amazing job
I have two four-in-one esc's from the mini Magnum V2 that just don't get power can you help me figure out what's wrong with these
I have the same FC (though it’s the Racerstar branded one) and my 5V to the FC and esc is bad. I can connect it to BF and everything looks fine. Which is the 5V regulator.
do you know , how to flashing empty ESC blheli_s ? i was wrong to flashing the firmware
can i place any other similar cap in place of the missing one?
How to check part number ?
What temp are you setting the re-work station to?
Awesome great job!!
Great job liviu

Yes thats correct... but also doubles the voltage rating :;
On one of my ESC a Capacitor burned. The ESC still works, would you say it is safe to use it or should I try to repair/buy a new ESC?
well i would say add an electrolytic cap and go on but make sure nothing else is burned and clean the area a bit.
I had a tekko-s 4in1 that was working perfectly then all of a sudden just dropped out the sky. Now when i power it all the video,fc,rc etc get powered but the escs dont respond or get any signal from the motors so no beeps upon powering them and no communication in betaflight or bliheli.

can i replace the mosfet of diferent esc but the same amps...aikon35a 4in1 and emaxbullet35a
not really, you have to use the same part number. There are a lot of specs related to mosfets other than amps :)
in this repair video you said that you used the generic china mosfet
@@tianofpv1845 no, I said I took the mosfet out of a generic china esc. It just happened to be the same part number.
Livyu FPV thanks for your time...i also have revolt v2...i flashed it from flight one to betaflight 3.4 it successfully flashed but after a few reboots it was not boting up..the data/status led is not flashing...but the board has power
Livyu FPV and i tried to reheat and remove the f4 mcu and replace fresh solder but still no chance of booting....it cant detect via pc
Again nice job !
Did you ever rebal a Gyro?
normal gyros are not bga's so no reballing needed. But yes i have changed in the past gyros never did a video about it cause i had no fc's with that issues. If someone sends one i will most definitely do it :)
@@LivyuFPV mabey i get one for you. Same FC like this one frome the video
c'mon little MOSFET! :)
You still never made the video about how to setup kiss v2 firmware I’ve been waiting since February it’s almost been a year
The kiss fc v2 firmware is closed source and I said i cannot show you guys hot to do it. Sorry but kiss is a closed source firmware... But I guess you knew this. No hacks
Livyu FPV o ok
Thanks for replying back I’m new to kiss

Ahahaha you made me laugh: p yeah aio stuff tend to be noisy. The small ones not so much but still...
my gyro was broken on this one. Replacement flies shit!
I did not get it. Did you change the gyro and it's not working?
@@LivyuFPV the first one has a broken gyro. The second one flies bad.
