Minn: Terrific diagrams as usual!!
My Robart hinges are installed close to what you have on the diagram at the bottom. My hinge points are "not quite" as deep as the ones pictured, but the bevel has to be completly notched out in the aileron for the hinge to flex. I should cover my gaps..... but this method works great, and the gap is very narrow. Thanks again to all....
