ABSTRACT:
A kite includes an arrangement of elongate, flexible rods interconnected at one or more joints to define a frame structure. A primary tensioning system provides a reactive force, in response to a wind force exerted on the frame structure, to thereby increase frame rigidity and resistance against bending and breaking of the rods. Secondary tensioners absorb the wind force and provide resistance against deforming of the frame structure when under stress. A net, secured to the frame structure by the secondary tensioners, extends across a front face of the kite. The net, having an open weave construction, provides no resistance to wind forces. One or more panels, formed of a thin film material, such as lightweight fabric or plastic, are selectively and removably positionable on the front face, against the net; the panels being impervious to air flow and thereby defining a wind confronting surface for providing wind resistance. A handle, operated with one hand, includes three different positions to affix control lines of the kite, thereby providing adjustment of the speed and maneuverability of the kite in accordance with the skill of the user.
