David Gomberg, The Fighter Kite Book, 1992, 74 pages

A very good book: it describes the principle of fighter kite flying and gives very lucid instructions and explanations. It is mainly about flying techniques and contains only 2 plans: a basic hata-style fighter and a rok. The best book I know for getting started on this subject.
David maintains a home page for his kiting business Gomberg Kite Productions International.
