I like my 10C, sold my 9C to get it. I also enjoy my 5U and 6X, even a 6EXAP I use. I have three 2.4 Ghz receivers, but haven't switched over any planes yet, still on FM. The 10C has both 72Mhz and 2.4 on this early model. I like the screen, programming, and feel.
The most my planes have are 6 or 7 servos and 6 channels, so it's really more radio than I need right now.

I'm tempted to let it go and stick with the old 6 channel radios, my frequencies are clear now, and used receivers cost about $20-25.
