They seem to come in all kinds of shapes... de Havilland favored
elliptical, Cessna favors a swept back trapezoid, Mooney swept forward...
etc.

Aerodynamically speaking, what difference does it's shape make? *I guess
sweeping back creates a bit less drag than straight vertical. * But other
than that, we're not generating induced drag because it's not generating
lift. *It seems like area should be the only consideration. *

Obviously the Mooney design is faster.
