This is kind of ironic.  My ex brother-in-law completed his PhD thesis by writing a program to design the optimal glider wing for a given set of variables.  Wish he was still my brother-in-law but he was very difficult to communicate with.

Thanks for the tip on Compufoil.  I've tried a couple of others but had some technical problems.  I wish I could do it as PIMMNZ suggested.  Just haven't got the skill.
