ABSTRACT:
A flying toy of the boomerang type having at least three airfoils, or wings, equiangularly spaced about a central vertical axis and extending horizontally outward from a center portion. Each wing carries at its outer end an annular-shaped wing stabilizer having a circular, horizontally-disposed, outer edge whose diameter is approximately twice the horizontal width of the wing at the juncture of the wing and the wing stabilizer, and having a circular inner edge which is disposed in the same horizontal plane as the outer edge, and which defines a center opening through the stabilizer. The stabilizer has a convex top annular surface and a concave bottom annular surface extending between the inner and outer peripheries. During flight, the stabilizers serve simultaneously as airfoils, wing stabilizers, and a gyroscope for the flying toy. The toy also includes a tubular central stabilizer, concentrically spaced about the central vertical axis and extending upward from the center portion, which carries at least three equiangularly spaced, vertically disposed blades extending radially therefrom.
