The Theory and Practice of Model Aeroplaning

A practical manual that explains principles and methods for designing, building, and testing model aeroplanes, emphasizing the interplay of experiment and theory. It treats weight, aerodynamic resistance, balance and automatic stability, aerofoil and skin-friction effects, motive systems (rubber motors, springs, compressed air, steam, petrol, and electric), and propeller geometry and performance. The text provides empirical observations, experimental procedures, and construction guidance—covering materials, motor preservation and lubrication, gearing, and testing—aiming to enable systematic improvement of model performance through measured trials and conservative theoretical deductions.
