ABSTRACT:
The present invention is for a kite which in its simplest form has a first edge spar and second edge spar which are equal in length and attaching to a flexible coupling such that when the coupling is in its neutral position the attached spars are substantially orthogonal. A header spar shorter than the first edge spar and the second edge spar engages the flexible coupling such that at the rest position the angle between the first edge spar and the header spar is equal to the angle between the second edge spar and the header spar. A sail covering the spars forms a central delta sail surface with a first triangular elevator panel and a second triangular elevator panel attached thereto. The first and second edge spars bound two sides of the central delta sail surface. The first and second triangular elevator panels have one of their sides bounded by an edge spar and a second side bounded by the header spar. The spars attached to the flexible coupling allows the central delta sail surface to respond to changes in the wind by providing a self reefing sail. This self reefing sail and triangular elevators provide stability and controllability.
