Foil kite

They consist of a number of cells running fore to aft, some or all of which are open at the front to allow air to inflate the kite so it takes on an aerofoil section.

The aerofoil section means that they can still provide significant lift when parked overhead, unlike leading edge inflatable kites.

The Flexifoil kite, still sold today as a 'Stacker' has a solid carbon spar in its leading edge to maintain its shape as it flies.

In September 1988 a 460-square-foot (43 m2) version was flown at the Ocean City Sunfest breaking the record for the World's Largest Stunt kite.

The Sparless Stunter saw a very brief history as kite technology evolved by May 1990 the first version of the original Quadrifoil was flown in competition at Wildwood, NJ.

This results in tighter turns with less arm movement – this is important if sitting in a kite buggy.

The design was refined for more pull with the introduction of the 'Hi' series with an increased aspect ratio (wing).

The 'Hi' series was available in regular ripstop nylon, or also available made from 'Icarex', a lightweight polyester material that allowed the kites to fly in much lower winds.
