Hehe I'm not sure of anything greenboot! But I do appreciate your help. Using a long straightedge against the back of the wings, they seem to have an even gap on both sides.
I have no idea about the correct way to measure, but when I flip the plane upside down and measure from the back tip of the fuselage to the tips of the wings the wing on the right is 3/16" ahead of the one on the left. I guess that would cause the right wing to lift a little more rolling left?
