Well, I'm a Futaba man, well boie. Well, that is just what I learned with. Futaba. But, I was at my Hobby Stop/Store (HS) a few days ago and I was comparing the new Futaba 6EXA and JR XP662 computer radios. They are 6 channels. Well, I looked, and the JR just had more. But, really I think that is just what you learn on. Like, I had a O.S. engine on my trainer that I still have now, and that kind of engine is what I will probably stick with. But, I would perfer JR, but Futaba has ver nice radios too. But, I belive that either one of the many radio systems that you choose will fit your need. But, I hope that you have good luck. HAVE FUN. THAT'S WHAT IT'S AALLLLLL ABOUT...........Oh yeah, even though the JR has more "mixes" and programs, and all that kind of stuff (I AM NOT BASHING ON JR) I have heard that is isn't easy to program as the Futaba 6EXA. I'm sure that other will have something to say about the different kinds of good, programmable, radios out there. So, again have fun with whatever you choose. Best Regards, and GOOD LUCK.
