Today, I worked to install the aileron carry through. I completed the gussets for the fore/aft ribs, primed and riveted the gussets and clips, then turned my attention to the horns. I had to do a little trimming on the 1 1/16 inch holes to get clearance in a few places for the tubes and nylon bearings. I'll now remove these parts and wait until I've painted the interior before the final installation.
