An inverting wing propulsion system is disclosed. A vehicle body having a left side and a right side is provided with a wing drive assembly. At least two wings are operatively associated with the wing drive. At least one wing extends from each of the right side and the left side of the body. The wings are adapted to be driven by the wing drive assembly to engage in a reciprocating motion between a raised orientation and a lowered orientation. The reciprocating motion is characterized by a downward arcuate motion, where said wings fully extend from the body so as to generate an upward thrust, and by an upward motion, where the wings are retracted so as to produce reduced, minimized or negligible downward thrust.
