ABSTRACT:
A flying toy or kite is provided which generates lift by spinning as it rotates at the end of a loop of string. The toy is molded of foamed plastic, preferably of two major components including a wing to spin about a lateral axis and a disc-shaped central fin attached to the center of the wing. The wing has a molded channel forming receptacle for a dowel or tube which extends along the central portion of the wing and retains rotating fittings at its ends. The disc has a molded slot for receiving the wing and is increased in thickness adjacent the slot to provide suitable support for the wing and to improve its strength and resistance to damage.
