Many years in the past, I built a Zone 5 Vortex ducted fan sport jet. Dan's solution to the wingtip issue was nice. Each wingtip was two balsa blocks, an upper and a lower. In between went a thin piece of carbon fiber. You adhered the three pieces together and then glued to the wing such that the CF was centered in the cross section of the airfoil. When you shaped the balsa blocks and finished sanding you had that CF protecting the edge from dings. Worked quite well!
