I had to wait for the paint and primer to dry. After it was dried, I temporarily began installing the prepped Aft upper fuselage Skin and I soon realized it did not fit due to the forward GPS Antenna I installed some time ago. I marked the skin and trimmed a small half-circle out to accommodate the skin. Now that I’ve done this, I hope the Riser-Rail for the Sliding Canopy stops just prior to the GPS Antenna. I guess I figure that out when I start working on the Sliding Canopy Frame. Anyway, I temporarily clecoed the skin onto the upper fuselage. I will wait to build the sliding canopy rail system before I do the final riveting so I don’t have to remove rivets later.
