ABSTRACT:
A flying disc toy has at least two circular spinners rotatably mounted upon a centered axle. Each spinner has a number of fins which cause the spinner to rotate when thrown into the air. The spinners rotate in counter direction, thereby causing the toy to lift when thrown with a twisting motion. The subject matter of this application is disclosed in Disclosure Document #254258, dated June 4, 1990.
