Needed some photos for the FAA.... Popriveted the spar to the ribs. Hand Squeezed the hinge on top of the spar on top of the bottom skin. Only had to drill out two bad rivets. For both the flaps and ailerons be certain your worktable is flat and level. It will eliminate one possible cause of trailing edges that are not exactly straight.
