...and then the gimbal goes whacko cycling back and forth in the same direction as the tilt. The camera rights itself on power-on, then does the tilt thing and then the cycles. This all after a hard landing, but nothing (apparently) broken. Any ideas? Fyi, I did the gimbal drive inspection, suggested in a related thread, but this model has a d shaped shaft and seems to be aligned properly. I also notice that the flat camera base and the gimbals seem hot, but I don't know what "normal" is. Any help would be appreciated!
