I need ideas of wing system for ultralight glider (such as Chanute, EasyRiser or Primary Instruction Glider) (may be biplane) low speed (25 - 40 hm/h) , weight of glider < 40 kg).
My idea is next:
biplane (wingspan - 6m, wing chord - 1.2m),
S1210 airfoill (http://airfoiltools.com/airfoil/details?airfoil=s1210-il).
There is no talk about materials. This is question about design only.
Please, write what do you think about this idea or suggest better idea (airfoil, flaps, ...).
Thanks for answers.
