KASTESKIVE

A flying disc with a central opening utilizing a plurality of concentrically arranged annular sections with at least the innermost ring having a unique sloping surface resulting in improved stability in flight. In the two annular section version of the disc, it is comprised of an outer annular, lifting surface concentrically surrounding and connected to an inner annular ring by a series of struts providing a circular pattern of slots between the two sections. The inner annular ring is shaped to incorporate a continuous dihedral angle between the inner and outer edges of the inner ring that provides great lateral stability in all flight attitudes.
