I’m a newbie in Pixhawk. Just flew couple times and today evening right after 1.5min of fly copter just started very fast rotating and crashed down (Before this i had 2 crashes in AutoTune mode when it switched to Yaw tuning and not yet analyzed it).
Can anybody help understand what happen and whats wrong ?
My first look on logs I can assume could be:
Some issue with GPS/Compass Fixture (probably from previous crash) - as a result in Loiter it started randomly rotating and dropped drone down
I would like to add following - I had replaced broken parts of frame, but then figured out that one of motor was with lots of dirt, which i cleaned, but it still rotated with force and when i try to spin the motor by ESC - smoke came from him.
The question is - was it die in the fly OR at the ground when crashed … ? By reviewing logs i see acceleration in Z, therefore it’s possible that motor slow speed and drone crashed via spinning down.
I appreciate any help investigating logs. I need to make sure that electronics is fine and that was a mechanical issue of motor.
