Upon recommendation from friends as well as several posts in forums, I upgraded my P2 to the Futaba 14 SG in the hope of having a better range and more stable transmission. Tried everything, all works good, BUT no range. Usually at around 900m FS kicks in, sometimes if lucky I get 1100m, but no more. Was sick and tired of it, especially after spending this amount on supposedly good RC system. I hooked up the standard DJI transmitter and now have a beautiful 3500m range. So if someone wants extended range, thinks twice about the Futaba.
