After trimming the rear spar, I leveled the fuselage, and checked the sweep of the wing. Now there was no sweep at all, and a plum bob at the leading edge was perfectly straight. I set the wing incident as required with a 3" spacer measured between the spars. I then drilled the rear spar for the attachment bolt. Drilled the holes in the lower fuselage skin for later attachment with screws. Drilled the fuel tank attachment bracket to the forward fuselage.
