Does any Futaba transmitter or receiver allow the pilot to choose between negative or positive shift, thus allowing a Futaba transmitter to control a JR receiver, or a JR transmitter to control a Futaba receiver? My understanding is that this is not possible with any Futaba system, but I have someone assuring me that the 8U does this. I am assuming that he is probably confusing another feature with this, and I just want to confrim. Thanks.
