On the second picture.. should the grey (aileron neutral) be perpendicular to the aileron? and then blue / green be moved accordingly?
Juan (LNEWQBAN) hit it on the head. I guess I was a little unclear on that.
Picture #1 shows one way of getting differential. Picture #2 shows another way. If you do both, you will get even more than either #1 or #2 by itself.
He was also correct in saying that Picture #2 is for a low wing. His diagram would be correct for a high wing.
