Interesting note: On the dual rate for my DX6 I had to drop AI0 and EL0 to 50% to gain super solid stability in a close quarters hover. AI1 and EL1 I left at 100% for upstairs flight (15ft+). I backed the expotential off to zero%. Seems to like these settings very much and is very "hands off" at this point. I don't know how it will act outside though with a slight breeze maybe pushing on it. Flipping the dual rate switches would only take a micro second to put it at 100% should the need arise.
