Plane modelling in the past was a kind of activity which was primarily related to the young population. This is not the case today because many people of different ages, occupations, and level of professionalism are dealing with plane modelling. Many companies managed to find the significance of this interesting activity. There are many types of model planes, but the most important ones are by type of drive, shape, and purpose. They can be either with or without the engine. The engine can be powered by a tire, a miniature internal combustion engine (SUS), an electric motor, a jet engine or a motor driven by carbon dioxide.
Types of flight
Engine and non-engine models can be left to airflow during the flight, so we are talking about a group of free flight models. They can be operated by two wires while spinning in a circle for a circular command flight. The third type is a radio-controlled model which is obviously controlled by radio device. The free-flying model is the largest group. It can fly freely on large surfaces without any side effects, and the races take on a 7-start flight.
Radio-controlled aircraft (RC aircraft) is a small, remote-controlled aircraft. There are many different models, from small flyers to big planes and acrobatic models of medium size. The planes are using different types of fuel or power, from electric motors to internal combustion engines to the most expensive jet turbines. The fastest aircraft can achieve a speed of up to 447 MPH while new models can develop up to 298 MPH within a short range.
Materials for model planes
When choosing a material for building a model, it is essential for it to be light and firm. Therefore, wood-based materials, such as slats, plywood, and veneer are mainly used for the construction. The slats are cut from linden, spruce, balsa, and other parallel wood. A paper and various plastic foils are mostly used for upholstering a model. For the needs of modelling, there is a special paper with fibre structure. One of the essential parts of the material is also the rubber for connecting special parts, which in some models also serve as a drive. To strengthen the upholstery cover and the moisture resistance as well as to reduce the warping effect the models are painted with special varnishes. Finally, the individual parts are made up of nitrocellulose, two-component glue with a high degree of strength.
Components of a model plane
The flying models consist of several elements each of which makes separate parts including wings, body, and tail surface. In addition to these parts, there are also the engine, ellipse, and wheel, although some categories are without a wheel. Wings, body, and tail surfaces are referred as the main parts and are usually interconnected by rubber. Such connection makes it possible to safely mount and dismount it as well as to easily replace the plane. It also allows a better safety of certain parts from a possible break.
