I think you're outa luck....from what I recall, JR shifts their signal one way(+ve?) and Futaba shifts it the other way...the end result is that they don't talk to each others receivers. You can get a Hitec receiver which has a jumper you can move to let it select which shift it receives... that might be an option for you... or you could get a an Airtronics RD series TX or Hitec eclipse/optra and be able to talk to anybody's (non PCM) receiver...that's a little more expensive though!
