ABSTRACT:
The Horizontal Axis Rotatory Frustum Toy is a catapulted cylinderlike flying-wing glider that rotates horizontally to produce lift and quite slow flight, suitable indoors or out. A rubber band or string can be used to launch it. Unique shape provides good lateral stability. The design principle may have military dispersion bomb applications.
