A scale model is actually a copy or a representation of an item or object that is smaller or larger as compared to its actual or original size. Mostly, it is a smaller representation and serves as a guide to the original object. Scale model airplanes are an archetypal example. There are many reasons why a scale model is made. It serves as a prototype and is used to test the performance of the object in its initial developmental stages. Architects use them as a display model for customers to evaluate and purchase the real object. Salesmen use them for the purpose of new product promotion.
Wood, plastic and paper are generally used to create a scale model. Scale model airplanes are of two types: static and flying. The former is generally made of plastic. However, metal, paper and wood also make good models. Military aircraft and commercial airliners are the most common scale models in this type. The number of manufacturers of the static type has dwindled today as compared to the 1970s and the popular scales are 1:144, 1:72 (the highest), 1:48, 1:32 and finally 1:24.
