I have power cycled and re-installed all apps/ firmware and still no tilt. On the last day the tilt was working, I would need to fly the copter within a few feet in order to use the tilt function. It would not work at a range of 10ft +. The next day I take it out the tilt does not work at all! I am thinking maybe the antenna is bad inside of the camera? Any suggestions would be much appreciated.
