Do you know why the wings were shaped that way?

So Zero pilots could easily identify what was about to blow them out of the sky... ;-)

The “bent wing” was to provide the extra ground clearance needed by the 13’ propellor, because the landing gear could not be made longer (either because of strength or to fit into the chord of the wing, I don’t know which).
