I set up my new Phantom 2 with zenmuse gimbal tonight. Everything seemed to be working so I shut it off. Later, when I turned it on again...the zenmuse would start off in the proper level angle...but a few seconds later, would tilt over and point straight at the ground. I downloaded updated software and now the gimbal stays in the proper horizontal pitch, but moving the lever on the back of the controller has no affect on the gimbal at all. Frankly, I don't care whether it tilts or not, since I want to keep the camera pointing parallel to the horizon, but there seems to be a big problem with the calibration which I can't seem to solve.
