Okay, time for final alignment of the control stick, ailerons and flaps.
I centered the stick. Aileron's were just slight off. I adjusted just the right aileron so that both line up perfect with the wing tips. And sure enough the flaps just about line up with the ailerons. They might be 1/8 low, but they are up as high as they will go.
I also made sure all linkages were tight and painted.
