Plane rolls at different rates left and right?
I have a 90 size Extra 300. The plane is set up with aileron differential on both sides. When I roll to the right, the roll is axial and fast. when I roll to the left, the roll is noticeably slower and the plane corkscrews thru the roll. I have measured the aileron deflection and differential on both sides and they are the same, linkages are the same, etc. The differential is controlled by end point adjustment on the radio.
Anybody have an idea?
