Having some problems getting decent range on my p2v. its never goes more than 200m away with out loosing connection and RTH. so I fitted 2 tp link 8dbi Omni directional antennas, one to the range extender and one to the controller but when I tested it nothing seems to have improved. Its switched to fcc mode?(2 beeps) tried searching the forums but have not had much success. any help would be much appreciated
