in blackbox you may find I am turning my arm off often .Sorry for that I had no other clue to stop drone when it was about to hit wall I had to stop props for minimal damage.
please see what might be wrong here .

What are you flying? I don't have a Blackbox analyzer that works, that file of yours reads almost blank to me. Some DVR or video would be useful
