Jtisch's photo in post #13 helps illustrate one of the subtle but important differences between Proctor and other kits. Notice the slight curve or undercamber in the wingtips when compared to the Sopwith's in the photo. When doing my laminated tips I made sure I didn't lose that aesthetic detail. It makes the whole wing look wafer thin. In the photo below I soaked 3 strips of 1/16" balsa in ammonia water, smeared them with a liberal amount of Titebond II and hammered them in place on a tracing from the plan. An exacto handle and some AC electric wiring staples convinced the part to shape itself into an airfoil. I'll let it dry overnight and see if it holds its shape.
