I've got 2 JR XS3s if you are interested in one of those. I've got the standard one, or the Pro, both come with servos, reciever and box. Both used for a short period. They are nice radios, I just needed to get something compatible with Spektrum. Are you in Southern California? Let me know if you are intersted.
Oh, and jw92656, the glitching with Airtronics' synthesized radios is to do with the Airtronics reciever, not the transmitter. People with the M8 and synthesized setup from Airtronics have the same problem. It's been pretty well documented on this forum, and everyone I know at the track that ran them went to either a Novak reciever, or back to crystals.
