Another option to Javafoil is Profili which uses X-foil. If I can be of help in offering to do some runs w/ this program give me a shout. Just state the airfoil # and Re: numbers you want, what data exactly you are looking for and I'll see what I can do..

Ernest,

    Mockups are only in my mind at this time........I would like to see your Javafoil  info

as I think it would be helpful to exit cooling air at or near separation point if I am

correct in what I think I know (very little) about the subject !! I am on dialup , can I

get you to burn me a cd !! E-mail me privately with your address and I will send cost

and postage......
