Sorry abou the crash.
I’m not sure but what I can see is:
- 4:40.5 to 4:41.0 RC throttle is lowered from 0.12 to 0.05.
- 4:41.5 thrust spikes to 0, then goes back up.
- 4:41.5 to 4:41.9: battery current goes from 9 A to 1 A, so either 1 or all 4 motors stop using power.
- 4:41.55 angular rate starts diverging, attitude is lost.
From the plots I can see that PX4 is doing everything it can to try to control the vehicle but either 1 or more motors are not reacting. My suspicion is that one motor turned off due to a hardware issue like wiring/cabling or the ESC did not spin it back up after that dip.
Was the minimum throttle set correctly? So did the motors spin after arming when idle on the ground?
And did you notice if one or all motors stopped?
