An electric VTOL aeronautical apparatus is disclosed that has folding wings each having an inboard wing portion coupled to an outboard portion via a hinge. Folding wings are known to be used during flight, although using a motor to fold and unfold the wings. In the present disclosure, the motor with its concomitant weight and complication is obviated or reduced by making the rotational axis of the hinge such that end of the hinge on the leading edge of the wing is displaced more outboard and lower than the end of the hinge on the trailing edge to allow the wing to fold and unfold passively. When in forward flight, a folded wing has more of the underside of the wing facing the flow, which pushes the wing upward, i.e., unfolding the wing. When the aeronautical apparatus transitions to vertical flight, gravity pulls the wings downward into the folded position.
