I have seen it recomended many times..... Futaba 9 C. I know you said you didn't see a need for more than 6 or 7 channels but what most people don't seem to understand about most 6 or 7 channel radios is the limits of its mixing abilities. 4 servo wings (gliders or Ultra Sticks) Dual elevator servos that can be linked to the trim using 2 different channels. I have been using a 9C for a year now and have not used more than 7 channels on an Ultra Stick but I used almost all the mixes. The ability to asighn fuctions and directions to switches is also nice. If you want just the trans only servocity has it for 289.00 with a standard feq modual. You can also get Futaba's spectra modual to be able to change freq.
