Abstract

A novel flying toy comprising a ringed or banded rotor launched by a pulled string. The rotor has an outer ring or band and an inner circular disk connected by a plurality of curved blades. The rotor rests upon a spindle set in one end of a handle grasped by the user. The rotor is loosely held by pins in the spindle. A string is wound around the spindle and pulled by the user. The spindle and rotor are spun rapidly causing the rotor to lift off the pins and into the air. The outer band contains air near the blades, and coupled with the configuration of the blades, contributes greatly to aerodynamic lift and flight stability.
