Shaping the wing like an airfoil reduces its drag and allows it to reach a greater angle of attack without stalling, but the airfoil shape is not indispensable—it’s a refinement. Angle of ...

This can be achieved by using an airfoil (wing) profile, which is a shape with very low drag. I made and fitted two external guides (I call them Edgarwits) to my Gen 1 Honda Insight, using ...
