Flying my p4 over the weekend, never a problem until this time. During flight, my gimbal locked itself all the way to the right and upward as if it was initializing, but stayed that way until it came back to me. I landed and reboot the copter and it went away. Flew again with no problems. I was wondering if anybody else had this problem, and if so what can I do to prevent this from happening again. Any help would be appreciated.
