There are several different types of flying line available including low-stretch cotton, waxed linen, braided nylon and twisted or braided Dacron. The larger the kite, the stronger the line you will need. The tether is the line by which you maintain control of the kite. The sail is the expanse of paper or other material that catches the wind. Spar A spar is a structural member that supports the sail.
Most kites have two spars a vertical spar and a horizontal spar.
The bridle consists of two short lines that are connected from points on the upper and lower vertical spar to the tether. Although some kites do away with the bridle system, it has an important advantage of being able to adjust the tow point for wind conditions. Tail A tail is attached to the bottom of the kite to provide extra weight and drag to stabilize the kite and keep it pointed upward. Drag Drag is the force that the wind exerts against the sail of the kite. It is the resistance to the kite s forward movement.
