Hi everybody, I just bought a phantom 2 incl h3-3d gimbal. Gopro 3+ installed. afterwards installed drivers and most recent firmwares. And now the issue; when the drone is starting everything seems fine. the gimbal calibrates and stops facing down. It's time to start the rotors.. gimbal still answers my controls (when moving it up and down etc. ) But when in flight the gimbal is not responding smooth and just jumping after seconds regarding my instructions. Also, the gimbal is continuesly (every 2 seconds) sort of twitching up and down (in a vertical way always, but sometimes also horizontally). I tried everything, reinstalling firmwares, other h3-3b rubbers (maybe this is caused by vibrations or something), adjust gains, start up in an northern direction.. I dont have an anti interference board on it; can it help? I dont think if Im looking to the technical purpose of it.. Anyone an idea?? Thanks a lot for your time in advance!
