O.k. now. This is my sequence of how I attached the wing tip pannels. Basically a dowel plug is glued into the top of the wing, flush w/ the surface and up against the wing tube socket. It is resessed so that the socket head cap screw is flush with the surface of the wing. The al. tube has a hardwood plug glued in it and is tapped for the cap screw. Important! do not drill through to the other side of the al. tube. Also if you are using the original seam for the wing tip parting line, then for even greater strength these should be on the bottom of the wing. But with my short tips, I can lift the 20 lb finished model by the wing tips with no problems of seperating at the bott. of the airfoils seam. Here's my wing tip cannoes. Ha! Ha!
