About the wing profile, I don't have any idea what NACA profile TT used for this model. When I rebuilt the landing gear mounts on my 1st generation TT Rare Bear, I traced the rib pattern using copier paper. I made patterns.by using small slightly over sized blocks / rectangles of paper, laying it up against the rib, then pushing the paper against the joint where the rib met the skin with the edge of a popsicle stick. I then carefully cut out the pattern, and checked the shape against the rib I had just traced. If it wasn't exact, I made small adjustments of the original pattern by transferring the original to another piece of paper with the appropriate changes.
