Rich,
Yes, as has been said.

I have a 6XAS and usually bring 2 or 3 planes to the field. My Sportster is Model #1, Sportster Bipe is Model #2, Dynaflite Mustang is 3...., Cub is 6.... Takes (I think) 3 or 4 key strokes to switch between models.

One thing to keep in mind, and it's small. The Futaba 6XAS (& 6EXA probably) uses model NUMBERS, not names. I think a couple of the JR's allow you to put in 3 or 4 letters instead of numbers. ie, my Model 1 might be Spt, 2 might be SpB...

All I do is put a number inside the fuse of each plane so I remember which Memory number it is.
