I agree with Sam, the aileron trim and autopilot work very well together.
I have the dual trim and autopilot, and I use them all from time to time.
Maybe I am getting old, but in my 8, I do enjoy being able to relax a bit to look around, or get that map when I am alone, and the autopilot helps, or maybe it is just a luxury I enjoy after flying Army rotary wing for 13 years and never being able to release the contols!
But one thing remains constant, hand flying the RV is just a hoot all the time.
