A rotary kite consisting of a single elongated airfoil element or wing with two perpendicularly attached circular stabilizer elements positioned on the airfoil so as to enclose a central longitudinal quarter of the airfoil element. Each stabilizer disk has an elongated S-shaped slot centered upon its surface through which the wing is inserted thereby causing a wing cross-section to have an S-shaped configuration. A dowel-type shaft is centered laterally on one side of the airfoil element and serves as an axis of rotation for the airfoil and its two stabilizer disks. Multiple bracing lines interconnect both disks and each line further extends to both ends of the shaft thus holding the two disks semi-rigid and perpendicular to the airfoil. A nail at each end of the dowel secures a plastic bearing to which a bridle line is attached and the unattached line ends are joined to form a V-shaped bridle. The revolving motion of the airfoil is sustained by the air movement into the airfoil\s upper half forcing that half forward and downward bringing the convex lower section upward and into the concave upper position in place for the next half-revolution.

A rotary kite consisting of a single elongated airfoil element rounded at each end, a dowel-type shaft extending from slightly beyond one end of said airfoil element to slightly beyond the other end of said airfoil element, said shaft being mounted upon only one surface of said airfoil element and being centered upon said surface, a pair of circular stabilizer disks mounted on said airfoil element, each disk containing an opening at the center of the disk for passage of said shaft therethrough and an elongated S-shaped slot to accommodate passage of said airfoil element therethrough thereby causing the airfoil element to form a concave shape on one side of the shaft and a convex shape on the other side of the shaft, and a plurality of lines attached at specific locations on each disk for interconnecting one of said pair of disks with the other of said pair of disks and for anchoring the disks to both ends of said shaft.
