I have a 6X, 6EXA, and 10C on 72Mhz.
I use the 10C mostly now, and a few planes are on the 6EXA PCM.
The 10C is a module radio, version 1, so it also has the 2.4 Ghz module, and its programmed with all 24 RTF planes found in various places in the house.
Instead of any preference for modulation, I just like easy programming radios, and all are pretty straight forward for me.
All 24 planes are RTF, no time to list them all.

Not one of them has a bushed engines on it, and none ever will. It's personal preference like climate control and power windows. I also don't like airbleed carbs.
If a radio has flaperon, throttle cut, exponential, and high rate for rudder so I can play with flat spins, I'm enjoying my hobby at a level I fly at.

Reading other posts, I'm fully in agreement with super deals like six Futaba PCM receivers for $30 each. I think I'll say PCM is going to be my favorite modulation for the buck.

Channel 36, 42, 52, a sharpie tells me which planes are on what and if I've got a NIMH or NICAD inside with it's MAH rating as I field charge on last minutes notice usually and don't want to remove a wing to see.

3 are marked 2.4. They are in a Super Skybolt / Surpass ll 91, a Midwest Hots ll/Rossi 45, and an Ultra Hots I fly and wouldn't want anything to go awry in, assuming 2.4 gives me a slight improvement on a reliable interference free signal, so I was told. I can always replace a Stick and AX 46 on 72Mhz and so forth.

By the way, did you know the masses are waiting five months for the arrival of the Aurora 9, and they are STILL waiting foolishly for Hitec to find a buck to ship them out?
