I was out flying today and it was about 10 feet off the ground, hit a tree head on at moderate crusing speed...

So now I dont get any action from the camera or gimbal. It just sits there limp and I get no video feed. I dont have any visible physical damage at all on the unit. Anyone know what couldve happened? maybe a reset of some sort?

Id unscrew the backing of the gimbal where the cables go into it and check for any damage in there or along the cables.

Do you notice whether or not the gimbal motors have any friction when you move them by hand while the aircraft is turned off? Like post #2 mentioned, you would want to check that the ribbon cable isn't damaged.
