About This Book

This practical guide introduces model aeroplane hobbyists to the history, materials, and step-by-step construction techniques needed to build and fly models. It explains propeller design and carving, wing and frame construction, assembly, launching methods, chassis and pontoon fabrication, and includes measured diagrams and photographs. Sections survey powerplants and propulsion — rubber, compressed-air, gasoline, steam, and carbonic gas engines — and offer simple engine plans and performance data. The work also presents notable record models and flight examples, practical advice on forming clubs and competitions, and a concise dictionary of aeronautical terms for beginners.

GASOLINE ENGINES

THE JOPSON 1 H. P. GASOLINE ENGINE FOR MODEL AËROPLANES

During the past few years several attempts have been made, both in this country and abroad, to produce a reliable gasoline engine for model aëroplane work, but mostly without any degree of success. The reason for this inability, no doubt, is due to the scarcity of small working parts sufficiently light and at the same time reliable. The engine described herewith, designed by Mr. W. G. Jopson, a member of the Manchester Aëro Club, England, is one of the few that have been made to work satisfactorily.
