Hi Dan,
How far along are you on your Windancer? That's interesting about the pressure distribution airfoils. Could I ask what the mission of that ship will be? Would love to see some teaser pictures if you could. Like you said it's just interesting.

Compared to the Carbon Dragon airfoils, they will be thinner (14%), have much lower drag at low lift coefficients and have lower maximum CL. The mission is somewhat different, however.
