All Inter Active Kite's quad-line variable geometry kites utilise the concept of aero-elasticity in their construction to produce a variable wing span depending on the mode of flight.
In straight flight as the kite accelerates the wings sweep back providing increased speed and stability with dead-straight tracking. The sudden acceleration provides a sort of turbo boost to the kite.
When the brakes are applied, or forward movement slows or stops, the leading edge
opens out allowing infinitely precise control and super fast propeller spins.
Unlike other quad-line kites some tension needs to be kept on the brake lines in
normal flight so that the sail does not flap and the kite can attain its swept mode of
flight. The handles should be held in balance in the hand so that the tension on both the
top and bottom lines can be felt and controlled resulting in near silent flight.
