I bought the Hitec 2.4 module for my Futaba 9-C radio to make it 2.4 then just started buying new Hitec RXs for my planes, very simple. Just remove the old RX and plug in the servo leads, bind and fly. There is a bit more to it like checking everything out but that's normal even when I installed any new RX in 72. Not a big thinker.
