Abstract: Two stunt kite handles are connected together by detachable couplings to form a winding frame which has oppositely extending winding posts for receiving strings wound thereabout in a figure-eight pattern. The handles are also provided with oppositely extending pivot posts which, when loosely held, permit the winding frame to pivot about a rotational axis to facilitate the release of string from the device. Each of two control strings is wound around a grip portion of its respective handle; and, both strings are wound in figure eight fashion around the winding posts.

Abstract: A ram-air airfoil stunt kite has its upper forward edge provided with two stiffener members that provide a rounded leading edge and are connected together by a flexible joint. Two operator-held control strings are connected to bridles which are, in turn, connected to keels on the kite. The outboard bridle strings are shorter than the inboard bridle strings so as to remain taut during normal flying operations. When the apparent wind velocity increases, the kite becomes transversely curved, whereupon the inboard bridle strings become taut to establish an optimum maximum curvature.
