Set the wing incidence, checked the dihedrial, drilled the rear spar and installed the rear spar bolts. The incidence is 0 with the required 3.03" block sitting on the rear spar and the front of the level on the forward edge of the main spar. The wing tip height is within 1/16" of each other. I checked this by pulling a nylon cord under the wing with two string levels on it, then measuring to the top and bottom of the wing.
