A try to design a gentle foil. It's (almost) finished, I just need some wind to test it in the buggy. The first test (static) show some promising behavior. The air intakes are maybe a little too much on the upper skin (to be confirmed).
Specifications : 3.38m span, surface of 3.0m², AR 3.8. 18 cells. Profile : MH93 mod (17%). Two closed cells at the tips.
