Bob, I usually use around 20% expo on the elevators and ailerons, and maybe a little more on the rudder for IMAC rates. I do spend a lot more time tweaking those rates versus 3D rates, where it's go for everything and use expo to make it flyable for normal maneuvers.

Well at least since a stud like me left
