Vern, if they are both RX-18 or Taigen Electronics then yes. The MFU for them are equipped to do both. Of course you will have to figure out how to mount the IR receiver (You KV might have a spot for it already) and also a place to put your IR emitter.
Is this permanent or just to try things out ? If it is permanent, then the BB warning LED is a perfect place for the IR emitter as that's what they would do in the factory.
