Sorry to hear about your crash.
From the log it looks like that at time 3:43.200 presumably some ESC/motor/propeller(s) failed and it could not correct attitude and altitude anymore with only 3 outputs.
Does that match what you observed or found later? Can you do a test if fall motors still work?
Thanks for the input.
Yes, found a wire was disconnected between motor and ESC. I soldered to connect each other after came back home, but I can’t make sure which motor was, should be either motor 2 or motor 3.
motor 3 motor 1
pixhawk ^ (^ means direction)
motor 2 motor 4
