So what you're saying is... the JR goes back or I buy 3 new receivers for my 4 planes (the JR came with an R770)? I guess I do have a decision to make cuz I plan to fly heli's someday. Maybe I can get enough out of my Futaba 6DA programmable and the 4 servos to buy a couple JR or compatable receivers...Hmmm...Thanxs for the info. Mike
