RE: RX and TX compatability
proportionality and channel assignment lie completely withing the radio--not the receiver. The receiver simply relays the message from the radio to the appropriate channel. This is why rx's have channel numbers, and not control surfaces written on them. because with some radios, channel one is throttle, while with others it is aileron, and so on. The RX doesn't care what is hooked to that channel--that is the function of the radio. Just make sure the TX and RX are compatible (shift selection) and all will be ok.
