Mounted vertical stabilizor to fuselage. Drilled and did all final bolting of rear spar, forward attach plus two additional bolts to forward attach for no possible slip. Spent most of time on rudder, riveted bottom piano hinge, and a lot of time filing and fine tuning the rudder & elevator stops for perfect solid stopping. Other than fairings, empennage is permanently bolted and positioned on rear fuselage. Looks like a real back half of a plane. Also did flush-screw/anchor-nut access panels on rear fuselage. Came out nice so will redo wing access plates the same way.
