RE: After-market receivers
Yes. Hitec makes receivers that are compatible with Futaba. Make sure you get a negative shift receiver so it will work with your Futaba radio. Other than that, match the channels and all will be fine. All of the servos that you have will most likely plug right into the receiver. THe only non standard servos as far as wiring are the old airtronics (i'm told). As long as you have futaba, or hitec, or JR servos, you'll be fine. I use Hitec receivers almost exclusively with my JR radio....
