Installed the trim tab after allowing the pro-seal to fully cure. imstalled the Ride side elevator to the HS and marked the WD-605 control horn to match the center pivot bearing. Memoved and repaeted with the L. side elevator. Drilled both control horns and remounted the elevators. The center brearing pivot lines up perfectly and both elevators swing freely in both directions. Checked the deflection angle with a digital protractor and they are withing spec's in both directions with no binding or rubbing.
