Abstract
A hand-launched flying toy formed of three or more equally spaced and substantially coplanar blades or vanes radiating out from a central hub area. The blades are shaped to have minimum air drag and substantially zero aerodynamic lift. When launched the device climbs in a substantially vertical loop, spinning as it goes. At or near the top of the loop, the device (which has become inverted) loses its linear velocity, thereby causing the device to descend spinning to a substantially vertical, relatively soft landing near the user.
