I had my first crash today. Slowly flying sideways and clipped tree about 8 feet up, some twig size branches. Fell to the ground. Had to replace all props. Flys fine but gimbal doesn't work. Looked at it real close and can't find any broken pieces. Camera still works as far as showing an image but no movement. Readout on display on phone says "gimbal obstructed"... also "Aircraft motor overloaded, check whether gimbal clamp is removed". Any input?
