ABSTRACT:
A hand-launched rotary flight device comprising a central hub from which a plurality of preferably equiangularly spaced-apart blades extends. The central hub has a finger grip portion with which the hub is rotatable, which finger grip portion extends radially from a blade-mounting portion of the hub in a direction away from the blades. The finger grip portion is dimensioned and configured to enable manual gripping thereof, ideally between the thumb and forefinger of the operator, to permit launching the device by hand into a rotary motion flight path without necessity of a mechanical launching device.
