hello, Today i went to fly my raptor 30,done the usual, turned on the radio then the receiver and the heli wasnt picking up any signal. the battery was fully charged.After turning both switches on and off several times it seemed to regain signal,done a range test and after 10 feet or so nothing again. I didnt trust things so i went home. Im using a Futaba 9ch and a 9 channel pcm receiver with a deans antenna.All the wires seem to be plugged in ok. Im not sure where i should look for this problem,Could someone help please Thanks
