Model Flying Machines

A practical manual that introduces the principles of aeroplane flight and applies them to the design, construction, and operation of rubber- and motor-driven model aircraft. It explains lift, resistance, weight, and stability, then describes wing forms, elevators, rudders, fuselage construction, motive power and screw propellers, bearings and gearing. Illustrated step-by-step guides and templates show carving and balancing propellers, assembling frames, and fitting drive trains, while plans and instructions are given for several specific model types and for launching, winding, and flying them. Emphasis is on experimentation, careful building, and adjustments to achieve reliable flights.
