Abstract
Abstract An aerial toy having an airfoil made of sheet material mounted on a spine. At one end of the spine is a counterweight and at the other end of the spine is a manually gripping member. The center of mass for the aerial toy when performing as an aerial spinning toy is in the vicinity of the nose end of the aerial toy which includes the counterweight. A launching notch is formed in the counterweight for receiving a catapulting band. The airfoil projects outwardly from the spine and the dimensions of the airfoil decrease from the trailing section of the aerial toy toward the nose section of the aerial toy with the minimum dimension of the airfoil projecting from the spine being in the vicinity of junction between the counterweight, the body, and the airfoil. The aerial toy is converted into a toy glider by detachably securing a delta wing of sheet material to the spine. The delta wing and the airfoil are at right angles to one another.
