I didn't get any good pictures of the hinge point recess on the aileron and the wing. But while fitting the hinge pins, I cut a recess as wide as the pin and deep enough so that the center pin in the hinge is centered on the peak of the bevel for each surface. This should allow the gap at the hinge line to be at a minimal when permanently installed. Did that confuse you too???[sm=bananahead.gif]
