Originally posted by Justin Stiltner most r/c vendors also refer to "channels" when you buy your radio this is what lets you select the frequency at which it will operate this link specifies the various channels [tower hobbies list] For our uses we need surface channels (61-90)

Here are some more explicit lists, including the appropriate freqency flag colors for the antennas:

The voltage from the full-size FIRST Robot Controller PWM OUTPUTS is too high and will damage the EDU RC, voiding your warranty

We MAY be able to fix that with custom interface cables. I think the problem is that the IFI RC either uses 12V pwm pulses instead of 5v, and/or supplies +12v on the power lead. If so, you may only need cables set up with the appropriate current limiting resistors and zeners in the right places to ground to protect the inputs from overvoltages, and/or the positive power lead missing. (A "reversed connector" would have to be investigated and handled, too...)

Don't try it though, until we've checked with IRI about it. The new RC may be wired differently from the old one, too.

I was planning on investigating that soon, unless someone has already done it. Anyone here scope out the old RC's PWM signals yet to see their waveforms and amplitudes?
