My gimbal started tilting to the left and I have never crashed it in fact not even a hard landing. Sometimes during the flight if I make a hard yaw move in either direction it will come very close to level but then slowly return to the position shown. Found several quick fixes with googlefu. I can take the back cover off and align the flat part of the shaft with the top of camera and it will be level after reassembly. I then apply the green loctite that is recommended and it will stay level for a couple flights but then do the same thing again. Any suggestions?
