The first time I ran into what Dan is referring to was with a first gen Futaba 7 CAP. You could mix two elevator servo's on two channels, 2>7, but the expo nor the trim from ch2 would carry to ch7. Which was interesting since they allowed the aileron to carry from ch1 to 6 for all those mix's.
Its my understanding that Futaba fixed this oversight on a later gen of the 7C.
Back then I ended up getting a nice servo reverser from Electrodynamics to get around the prob.
Cheers.

Use 30% on the ailerons and elevators. If you use a ''Y'' connector for them you will get the same expo on each surface. If you are using different channels for each one it may be dependent on your radio. Dan.
Sorry, but computer radios put expo on the function, not the individual servo.
If there's any radios that are otherwise, please let me know which, because in my somewhat admittedly limited experience, I've yet to have seen one.
