Claim:
1. A flying disc, comprising: a unitary, one-piece hub composed of polymeric material and including a central axis, a circular and unperforated flight plate extending in a direction transversely with respect to the central axis, and a hub rim depending from and extending generally transversely to the flight plate and immediately adjacent the periphery of the flight plate; a circumferentially continuous ring composed of polymeric material, coupled to the hub rim, extending across substantially the transverse extent of the hub rim and in cross section extending radially outward of the hub rim, only decreasing in axial extent as it extends radially outward and merging into a generally rounded radially outer periphery; the hub and the ring have different specific gravities; and the hub having a specific gravity in the range of about 0.92 to 1.25 and the ring having a specific gravity in the range of about 0.96 to 5.0, wherein the ring includes an axially outer surface that is excurvate over its entire length and wherein the ring has a higher specific gravity than the hub.
