This kite flies on a different principle from most kites. In action it is more like the sail of a boat which billows out in the wind. In effect the action of the sail forms what may be called an anhedral angle, which is reverse in shape to dihedral.
It is a tailless type, and lacking the measure of steadiness which a tail provides, it can be rather erratic in flight. Nevertheless, its lively manner makes it an interesting kite to fly.
The framework is of the simplest kind, comprising a backbone and crossstrut (A and B, Fig. 3) which are arranged in the form of a cross. The kite can be made so that the framework will fold up for convenience in transport. Two pieces of 3/8 in. square stripwood are required. These are 2 ft. 6 in. in length. Notch these pieces at the ends and lash them together with fine string, the cross-strut being 6 in. from the top of the backbone. As this kite
may be folded up when required, no glue is used in making the framework joint. Tie the binding string in such a manner that it may readily be removed.
The bracing string is fitted next. Use thin, strong string and take it over the ends of the framework by means of the notches provided. Tie the ends at the bottom of the backbone.
The cover is made of lightweight cotton material, such as cambric. It is cut rather wider than the frame, so that it bellies out like a sail in the wind. Lay the framework on the material with an extra 21/2 in. all round, 1 in. of which forms the overlap, and cut out. When decorating the cover, mark out the design in pencil and colour it with fabric painting oil colours. A simple bold design is most effective, and bright colours should be used. Note that the design is painted on the front side, where the bridle is tied (Fig. 3).
To attach the cover, sew the 1 in. margin neatly down over the bracing string, but do not fasten it to the framework. In this way the cross-strut may be removed, laid along the backbone, and the cover wrapped round them when the kite is being taken from place to place.
