Even a flat piece of foam will generate lift [1]. The only requirement per se is that the trailing edge of the wing is somewhat sharp. A more optimized shape would allow the plane to fly at a lower angle of attack and would reduce drag, but drag isn’t exactly your problem if your thrust to weight ratio is 2:1.
