I am currently constructing a manoeuvrable glider capable of a fast pitch up (similar to how birds perch). For the design of my wings I was thinking just to use thin balsa wood sheets with an elliptical planform. I am aware that conventional aerofoils are designed to operate efficiently for AOAs below 15 degrees but I am interested in the manoeuvre, which will be at very high AOA (up to 90 degrees). My question is that will the aerofoil shape be really important for this case?
Thank you :D
