Singapore Airlines Boeing 747-400 scale display model Group of students with their wooden model airplanes in Sonta, Serbia, 1936. A model aircraft is a physical model of an existing or imagined aircraft, and is built typically for display, research, or amusement. Model aircraft are divided into two basic groups: flying and non-flying.
Tamiya made aircraft in the 1/100 scale in the '60s and early '70s but this was abandoned later on.In aircraft models Tamiya offers a few clear skinned kits showing interior parts of aircraft. A few motorized kits are available also which feature spinning props. Some kits even include sound effect modules. Tamiya's aircraft kits often include ...
In the second half of the nineteenth century, several theories were developed. The momentum theory or disk actuator theory – a theory describing a mathematical model of an ideal propeller – was developed by W.J.M. Rankine (1865), Alfred George Greenhill (1888) and Robert Edmund Froude (1889). The propeller is modelled as an infinitely thin ...
Frog was a well-known British brand of flying model aircraft and scale model construction kits from the 1930s to the 1970s. The company's first model, an Interceptor Mk. 4, was launched in 1932, followed in 1936 by a range of 1:72 scale model aircraft kits made from cellulose acetate, which were the world's first.
A folding propeller is a type of propeller whose blades automatically fold out when the engine is turning, and then fold back (or "feather") when the engine stops. Folding propellers are found on sailing yachts , on model airplanes, and increasingly on self-launching gliders and small motor gliders , such as the Aériane Swift PAS .
Early versions merely constrained the model to fly in a circle but offered no control. This is known as round-the-pole flying.The origins of control-line flight are obscure, but the first person to use a recognizable system that manipulated the control surfaces on the model is generally considered to be Oba St. Clair, in June 1936, near Gresham, Oregon.

A 6-bladed Hamilton Standard 568F propeller on an ATR 72 short-haul airliner. Lowry [27] quotes a propeller efficiency of about 73.5% at cruise for a Cessna 172.This is derived from his "Bootstrap approach" for analyzing the performance of light general aviation aircraft using fixed pitch or constant speed propellers.
