An interesting read on wing location last night. The F4U Corsair, though seeming to be mostly a low wing airplane, got aerodynamic credit for being a mid wing plane. Though the wings did not intersect the fuselage at the mid point, they did intersect square to the fuselage, so no aerodynamic wing to fuselage fairings were needed. It was the most aerodynamic arrangement possible for an airplane whose wings were mostly "low" relative to the fuselage. The inverted gull wing allowed for a large prop, shorter, lighter landing gear, and the aforementioned aerodynamic efficiency. The benefit of the shorter landing gear was not only lighter, and less spindly, but when retracted, would fit into the wing chord. This wing arrangement had more going for it than I had previously considered.
