Hi mate.
Could you send my files of GUAL 6.5 Please.
I'll email you the files when I get home later. It's odd that wingine isn't responding for you.
Yes, foilmaker is similar to surfplan. But I think surfplan is better. Surfplan has a builtin 3D Virtual Reality viewer so you kites can be designed in a 3D space. It's cool.
www.kitebuilder.com is a great source for materials. Very good prices.
They also have a great forum which you can find here: Kitebuilder.com Forums I have a few threads on traction foils there.
Cheers,
P.
