A flat wing is still an airfoil.

It's just not as efficient at producing lift. Thus, the plane needs to fly at a slight angle of attack. This is why many foamies are no where near as precise while flying, compared to a similar plane with a conventional airfoil.

Build time, ease of construction, and weight all play a factor as to why they became so popular. If the plane your planning on building uses a flat wing, it should still fly fine. It will just not fly as precise and or as fast as the same plane with a conventional airfoil.

Hope that helps.
