Installed wings and adjusted the guide plates and rollers. Checked wing incidence after leveling fuselage. Then we measured triangulation from firewall to back corners of each wing. It was withing 1/32"". Very happy with how easy this step was, lock pins slide in effortlessly after proper adjustment. Drilled rear spar holes once everything was set. Drilled aileron joiner and removed wings. Installed nylon spacers for rear spars. Began assembly of aileron push tubes.
