I like the computer radios for the exponential capability where you can make the controls real smooth at the center and yet have a pretty good total deflection

I also like separate aileron channels for each servo

I like the ability to feed a little rudder in with the ailerons and a little elevator in with the flaps

I like the ability to slave a second servo in with the elevator servo so I can run two servos on the elevator and program the slave servo's direction and total travel
