The Dual Line Kite Dual line kites are often referred to as ‘stunt kites’ as their main purpose is to perform the most amazing stunts. Over the years the leading design for this type of kites has turned out to be the ‘Delta’ kite. These kites are triangular in shape and have a high aspect ratio, meaning that they are wider than they are long. To keep their shape in the air stunt kites have spars and struts attached underneath the frame. For the best flying results these kites must be as light as possible and use only modern materials such as Ripstop nylon and fiberglass or carbon fiber spars or struts. To control a dual line kite the most popular method is to have the flying lines attached to padded wrist straps or bar type handles. The strength and length of the lines depend upon the size of the kite and the wind strength. A breaking strain of about 70kg or 150lb is about average. Again these lines will be made out of Dyneema, Spectra or Dacron. The illustration below shows the key parts of a dual line kite. Nguồn : Google
