Well, my hog is flying a plain old Airtronics old style FM (PPM) RX with a *very old* magneto 38cc engine - no glitches. But then again there is probably near three feet between the engine and the RX and I used nyrod for the throttle connection, on purpose.My first radio was a Futaba AM (the black box, forgot the model) in an Eaglet (cira 1985). Was flying it along just fine one afternoon when a thunderstorm cracked some lightning off in the distance I saw the flash out of the corner of my eye and the Eaglet did a beautiful snap roll, complete with the throttle timing and everything. Decided to land and pack it up (El Paso, flat desert and hold a lightning rod - didn't want to be the next discharge point)Anyhow, climb back off the way-back machine and now that we are here with 2.4 radios, I have a 72Mhz set that is pretty darn trouble free. I don't mind using it, even on a Raptor but I will only do that if I have no 2.4 RX's left. As RappyT said, just *much* more confident. No crystal to fall out (that's happened to me, airplane), no antenna to catch in the main rotors (yep) and no one else on the same channels, ever. The 72Mhz does work and works well but the 2.4 is *much* better. Also, that model match feature seems like a small thing, but it's a big bonus. It has saved me a number of times from a hot start. I did that at least twice with my Airtronics.
