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.
In a flying device of the boomerang type having a central vertical axis, a center portion symetrically disposed about the central axis, and at least three substantially identical wing portions equiangularly spaced about the central axis and extending radially outward from the center portion in a horizontal plane, the improvement wherein each wing portion carries at its outer end an annular-shaped stabilizer having:
