Went out to shoot on the water yesterday and decided to shoot a panaramic view of a local spot by using the camera gimbal, rather than by yawing the craft. I set the speed slow with the yaw knob on the controller (like I used to do with a my Typhoon) and the motion was jerky with the turning, rather than smooth, looked like it jerked a few degrees, stopped, then jerked a few degrees again. At the time, I thought I was getting lag since there were power lines in the way. Are there any known problems with the gimbal or control knob or could it have simply been interference?
