A recreational spinning ring includes a primary and secondary airfoil. The primary airfoil is located on the bottom of the ring near the outside rim and provides a downward force while it is in flight. An upward force is provided by the secondary airfoil located on the top surface of the ring closer to the inside edge. The downward force of the primary airfoil counterbalances the excess lift provided by the secondary airfoil so that sufficient net lift remains to keep the ring airborn. The improved flying ring has the ability to fly in an exceptionally straight path over intermediate and long range distances.

A spinning aerial apparatus which is suitable for throwing, including a ring having a top side, a bottom side and a circular opening in the center of the ring, said ring comprising: a first airfoil including a substantially rounded cross-section on said bottom side and a substantially flat cross-section on said top side wherein a first lift component is created by said first airfoil when said apparatus is thrown, said first lift component lying in a direction which is approximately perpendicular to said substantially flat section toward said bottom side; a second airfoil substantially concentric with said first airfoil, said second airfoil including a substantially rounded cross-section on said top side and a substantially flat cross-section on said bottom side wherein a second lift component is created by said second airfoil when said apparatus is thrown, wherein said second lift component is greater than and lies in a direction opposite to said first lift component, wherein the lift generated by said first airfoil counterbalances and neutralizes excess lift created by said second airfoil so the apparatus generates a net lift when thrown and is capable of stable flight on a substantially straight path.
