The trailing edge glue-up turned out perfectly. The trailing edge is perfectly in line with the aileron. I still need to glue up the trailing edge, but I wanted to reinforce the wingtips before doing so.
The wingtips need reinforcement since they can easily be depressed. This is because the wingtips just have a thin layer of fiberglass and no core material like the cowl to stiffen it. Many builders install foam ribs or dowels, but I wanted to try reinforcing the whole surface. I picked up some Coremat from Tap Plastics and bonded it to the bottom of the right wingtip and then added a couple of layers of 8.9oz glass.
Afterward, I installed the wingtip so that the fiberglass will cure with the right curvature. This took way longer than expected, and I still have the upper surface of the right wingtip and both sides of the left wingtip to do. You can see the pattern I made for the fiberglass hanging over the other wingtip.
