Abstract
A throwable or otherwise launchable aerial toy, which provides two relatively closely spaced colinearly aligned ring wings, with the forward ring wing being larger than the rear ring wing connected through a central slender member. The spokes connecting the rear ring wing to the central slender member can be configured in a fin shape to provide additional aerodynamic stability. The central slender member can be configured with a U-joint connection assembly to eliminate flight wobble due to manufacturing variations. The central slender member can also contain a rotating joint to permit the forward and rear wings or aerodynamic members to rotate independent of one another, separately or in combination with the U-joint connection in the same central slender member connection between the forward aerodynamic member assembly and the tail aerodynamic member assembly.
