Installed the NACA vents into the front cabin. I used silicon rubber caulk to seal the plastic pieces to the interior of the skin. I hope this doesn't bite me later when I go to paint the exterior. I used copius amounts of acetone to remove the blead out around the rivets and the joint. I also assembled the brakes including the cylinders. Riveted the fiberglass rudder cable fairings onto the fuselage.
