Hey guys! I'm new to this thread but I'm trying to sell my P2 with its H3-3d Gimbal already installed however for some reason now when I turn on the device it is stuck at like a 15-degree angle and won't go up any further (here is a picture: H3-3D Gimbal Broken..). I've tried plugging it into my computer and the controller. The horizontal/vertical tilt are both on 0. I've watched numerous videos and desperately need help because I am unsure what to do and want to get the new Mavic!
