First off I have crashed my drone in the past... but since then, have successfully flown and used camera on at least a dozen flights. Upon startup today, the gimbal rolls, spins, twists erratically and for at least a minute attempts to position itself unsuccessfully until I shut it down. I get a gimbal overload error message and once I shut the drone down, the camera faces directly down, but also at an odd angle (see photo). There are no guards blocking movement, I've tried the calibration (it fails and gives the overload error message), white shock absorbers and pins on the gimbal main mount seem fine, ribbon is plugged in at all locations and seems okay, latest firmware from Nov 2016 is installed, and I've checked for issues with the set screws and misalignment with shafts. Everything seems fine. When turned on, the camera actually tries to rotate downward and to point toward the rear of the drone. It of course hits the back of the gimbal mount since it shouldn't be trying to rotate in that direction, but the gimbal continues to spin and crash into the back of the arm trying to calibrate on start up until I shut it off. Any ideas?
