When I arm, all motors start spinning. 
Then motor4 sputters, and stops entirely.
Will not spin again until unplug, replug battery.

No BLHeli error shutoff beep.


What could be causing this!?

Anybody ever have anything like this?

I doubt this is a firmware issue but more hardware specific.

This is the GHF411 that somehow suddenly MCU died.
I flew quad many many months. Pull it off the wall.. no BLHeli chime response. After tons of troubleshooting, swapped working F411 from Flywoo board.

Now this.

Maybe hot air shifted something.

Hot air can be tough to focus the heat at the component you are removing or reworking especially on board sizes used in FPV.

Its not uncommon to unintentionally move other components.
