I'm trying to locate a Spektrum AR636A. (AS3X and SAFE) that hasn't been programmed for a specific plane. I did make a pretty nice flier with a M-7 Maule receiver in an FMS Kingfisher. It was a total shot in the dark but worked wonderfully. I have a brand new AR636, new in package, but is simply AS3X, no SAFE. I'll consider trades or money or something really cool.
