Crashed P3P when prop flew off (so much for self tightening props). Anyway it jacked up my camera. The camera is not quite level and when I manually straighten it I can hear a light grinding noise. Also, when I fully depress the camera it does not go all the way down. When left in the down position, the camera jerks slightly upward. This continues as long as it is depressed. Anyone know if this can be fixed or do I need a new gimbal? can one just buy a gimbal or does the camera have to come with it?
