Abstract
A flying toy for use in short distance indoor or outdoor flight games involving a single player or many players includes a low mass, resilient peripheral tension ring, a lightweight flight surface and an inner ring and may be maintained in flight by repeated tangential strikes to impart additional rotational and translational speed. In an alternative embodiment, a bladed flying toy includes a central hub and deflectable radial blades which cause the toy to rotate in a predetermined direction when the toy is pushed upwards and which, upon release, cause the toy to rise and then fall slowly downwards in an autogyro fashion while continuing rotation in the same direction.
