With the right aileron aileron jigged and aligned, I test-fitted the right flap to see how hard it would be to align the flap and aileron trailing edges. That part wasn’t hard but I did discover that when the flap and aileron TEs are aligned, the flap hinge wouldn’t have sufficient edge distance for the rivets that attach the hinge to the wing. I can’t do a better job of explaining this than Brad Oliver did, so see his website entry for more details.

Bottom line…just as Brad and others did, I ordered a piece of wider hinge material to give the required edge distance.
