Thanks XPO

I think that answers my question.

your setup is just how I figured it to be. sounds like a good idea. I have 3 RX's for the 421 72 band.

Your system would solve a problem in a way , but it may not be the way I want to go.

right now I have my radio system ( 2.4) set up so that I can let a student or anyone fly any of my 2.4 planes on the buddy system. I let a new person fly my Hanger 9 j3 cub last nite. It was nice to give him a feel for another plane, he says he wants to stay with the real traniner for now

if down the road I pick up a used JR radio with over 4 channels and one in not gear, my idea will work even better. I just can't use mixing for a plane with two servos for the wing servos with the buddy cord.

thanks for the reply, good luck with this. I may someday give it a try.
