Mike: what airfoil do you suggest for the modified wings? Just got compufoil3d, played with SD8020 but don't know if it well work right for this plane. I'm also having problems getting this file moved into autocad r14. Don't think that compufoil will copy a dxf file to a cd to that to a print shop to get plans for rib templates and wing planform.I can onlt get the ribs to autocad, no no wing layout.
