Hi everyone . I am using PX4 Qground-control . i did some flight and all went fine. the second flight , i tried to do some steep maneuvers ." pitch forward and backward" the results drove one of the motors to drop thrust and crashed the drone. i checked the flight data . one of the motors PWM dropped to idle ( any idea). a bit confused ?

Did the opposite motor go to maximim? If so, that’s usually an indication
that it has failed. The motor going to zero is doing to attempt to
compensate (almost always failing to do so).
Hi peterbarker,
I believe my tuning were underdamped system, so it went into oscillations and couldn’t recover . so what i learned is always over damp they system to avoid oscillations
