ABSTRACT:
A multi-disc flying device is disclosed in which outer and middle discs rotate in opposite directions by a force generated by the unwinding of a torsion spring. Downwardly extending deflecting plates on each disc generate an upward force during rotation to prolong the flight of the device. An inner disc rotatably attached to the middle disc has a normally curved rudder assembly to impart a curved flight path to the device so that it will return to its launching point. A propeller is driven by relative movement between the rudder and the inner disc to provide a propulsive force to the flying device.
