Default LS-3 Wing Profile Templates

Rick at Sundance Aviation, Moriarty, NM is restoring an LS-3 and asked me to
post a request for profile information for the wings.

Going on advice I've read on this site, I suggested to him that he pull
templates off the wings, fill, gel coat, paying attention to the first 6
inches back from the leading edge, and fair the rest paying attention to
waviness.

So, does anyone have templates, or is the consensus to do what I described
above?


The Wortmann FX67 series airfoil coordinates are available.
That said smooth and refinish is the most practical solution.
Worth noting, just to confuse you, is that this series of airfoils is
very sensitive to leading edge shape.
Most have been sanded too round.
If you're flying it for fun, don't worry, just enjoy it.
FWIW
