Abstract
A novel rotating aerodynamic toy comprising a ultra-elastic gel airfoil which is suitable for launch in light or heavy wind conditions and capable of performing various aerodynamic effects including climb, stall, return, straight-line flight and other aerobatics. The ultra-elastic properties of the airfoil allow the airfoil to transform its aerodynamic profile at launch and while in flight.
