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.

A MODEL WARPLANE

The model shown in the accompanying photograph was constructed by Master R. O’Neill, of Montreal, Canada. The machine was designed after one of the leading warplanes now in active service abroad and in carrying out the entire features he did not fail to include the identification marks which are of utmost importance in the war zone.

The dimensions of the model are as follows: Length of fuselage, 23″; span of top wing, 33″; span of lower wing, 29″, both having a chord of 7″. Motive power is derived from two ¹⁄₈ inch square elastic strands which operate a multiple gear to which is attached a 10″ propeller.

In coloring the model a dull aluminum was selected. Complete the model weighs 12 ounces. Perhaps the most interesting feature of the model is the ability to change it to a monoplane by the removal of the upper wing after which the lower wing is raised to the sockets in the fuselage which were especially arranged for that particular purpose.
