After calibration 1 motor has stopped working.i know trimming sometimes fires the motor up but in this case nothing seems to work .iv followed videos to the letter on setting up so I baffled by this accourance as it flew perfectly the last t ime out and I haven't crashed or had any hard landings.anybody got any ideas. P's I live in the durham area is there anybody,or shop with the knowledge to sort this problem out for me thanks.
