I replied to your post above in regards to a fixed wing Futaba Radio for helis. I have a 6 Channel Futaba Computer radio but didn't think it would work with helis since there are no pitch curves or cyclic/collective pitch mixing in the programming
I was thinking of a 7c or 9c - don't know which others have pitch/throttle curves in the fixed and heli versions. Still though, if the Futaba had dual rates or expotential, you would be ahead of the curve I think - that is what really helps flying a Pro.
