The new, fourth edition, is now available and was published in June 1999. It is on a larger page size with much improved layout and design.

This is a work on aerodynamic theory, as applied to model flight. It explains everything in a concise and practical form for those enthusiasts who want a better understanding of model behaviour. The latest revisions reflect developments such as powerful miniature turbojet engines and dynamic soaring. Photographic illustrations are included, all the diagrams have been re-drawn by the author, and there is new material to cover recent research and flight experiences. Almost every page has been altered in some respect to improve clarity and style although the main content is necessarily the same.

The book remains the only one of its kind in the English language.

The author is an experienced and active model designer, builder and flier, as well as a glider pilot with about 1500 hours solo flying experience.
