A novel rotating aerodynamic toy made of 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 by at least 50% extension of its aerodynamic profile at launch and; while in flight; one or more preselected sized cavities and holes, slots and holes, cavities, slots and holes and cavities, slots, or holes provide handling, elastic control of airfoil profile stretching for flight, and flight stability.
