Installed the right wing hinge attachment pins to the wingtip and wing skins. Cut open the trailing edge in preparation for mounting the rear tip rib. Due to the attachment modification, there will be some minor changes to the tip ribs. I cut the trailing edge to assist in better tip alignment. Also, I used my Fein oscallating tool with a cutting blade to make all the fiberglass cuts. It's a great tool and not nearly as messy as a dremel or die grinder cutoff blade. It also makes a much fiiner kerf joint.
