Mounted the left and right wingtips. They took a fair amount of filing to get them to fit to the wing skins. I made a template of the wing airfoil out of 3/4" foam board, and stuck it in the wingtips to hold the proper shape as I drilled the tips. The left wingtip did not line up with the trailing edge of the aileron. I had to split the aft edge of the wingtip with a hacksaw blade. As soon as the cut was made, the top of the wingtip lined up perfectly. I need to epoxy the two halves back together in the correct position. The right tip worked almost perfectly right off the bat...
