Hello all. i am new to flying ( havnt started yet ). I built a few planes when i was a teenager but never actually flew them. My wife knew i was interested in RC planes and bought me a hanger 9 P-51 arf. I know this isnt an ideal trainer. My uncle supplied me with a trainer that my 2 older boys and myself could learn on. It has no servos,RX or TX.I bought a Futaba 7cap from ebay ( not here yet ). I was wondering if anyone would point me in the right direction in the way of what RX and servos to get. I want to outfit both planes with the ability to use them from the 1 TX. The trainer is a 4 channel and the P-51 is 6 i think. Ther servos i found that i thought would work are the Futaba 3152. As for RX, i need 2 and have NO idea what to use. Is the 7CAP crystal? do i need to get 1 crystal for the TX and 2 for the RXs? or is the 7CAP the kind of radio that is programable? All i know about the TX is that it is 72 MHz? Some one plz help, i am lost []
