Hey Gang

I am in need of generating some polars for the prospective airfoils I want use on a new 40% scale bird I am working on. I have boiled it down to about four airfoils that I think will work, using "Eyeball 1.0".
I would be very grateful if someone could crunch the numbers for me, using something like X-Foil that can handle low Reynolds numbers. I just want the Polars plotted for me. I have the coordinates for the airfoils and can e-mail them to whomever can do the calcs and e-mail me the figures back. I am on a shoe string budget for this whole project but someday would like to purchase the software. Right now that is a back burner concept.

Thanx, Wolf

X-Foil is free software, why don't you download it and have a go?

There is no GUI other than the graphs, so you will have to do a bit of fiddling around with text editors and the command line. It's worth it.
