I think many know the situation: you come home from work – totally exhausted and again, eyes clinging to the instrument on the shelf and the “sticks” hanging on the wall since last year. Automatically then I remember that the season has long been opened and begin a frenzy to finish the plane… eyes, lying on the couch. However, this does not last too long. Comes a real enthusiasm and somewhere there is immeasurable energy. But… for some reason it always occurs exactly at the end of the season. And when more than half of the super-model is ready, a bad weather, the rains, snow and other delights associated with autumn. The plane is just so desirable again “hangs” on the wall. He rarely survives until the next season (or tide mood!), often “killed” by a caring hand of his wife, wipe the dust off it.

Have trace modeling particularly attractive trait: despite the relative simplicity of the models, they give space for the creative work of the children’s thoughts, development of design imagination. An illustration of this situation can serve as our mug on the car model “Stratos” (Fig. 1). Recently Moscow plant “Young technician” started to produce the engine of DP-15. He has two obvious advantages: its capacity is sufficient to move the model, and it is quite affordable. Another plus: when calculating gear, you can focus on the spur gear for electric shavers that are sold as a spare . parts. Cons — size and weight — when novice modelers can not be ignored.
First image of indoor model airplanes made of bird feathers, I saw in the years of the great Patriotic war, even as a boy. Father was at the front, and my mother and my younger sister and brother were among the evacuated from Moscow to Omsk.
10 years have passed since the moment when on the ice kartodromo countries started regularly played the championship of the Union and the RSFSR. In the winter competition includes two classes of racing and two classes of models-copies of planes with compression engines of 1.5 and 2.5 cm3. Today’s theme is the racing model of the sleigh, their schemes, design features, propellers, etc.
This schematic model airplane designed by M. S. Stepchenko, one of the veterans of the Soviet aircraft modeling. Its main advantage — ease of fabrication. Required for construction material: pine rack, a little steel wire Ø 0.6 mm, tissue and drawing paper, rubber thread Ø
Lately in the aviation modeling widespread flying models, radio controlled, including helicopters. For the first time such a model was demonstrated in 1959 at the all-Union competition of S. Vorobyov. To control the flight he applied the principle of changing the alignment of the apparatus. After a year in the championship, in the background, a helicopter appeared Borisov with an aerodynamic rotor drive. In 1964, at a match meeting of the athletes of Moscow and Leningrad, he introduced the concept of B. Yuriev new model with tail rotor. However, the car was “raw” and, unfortunately, remained unfinished.
The fuselage of modern rezinomotornaya model aircraft usually consists of two parts: the power (it houses the rubber motor, is attached to the lug screw, wing) and the tail boom carrying the tail surfaces. The power part usually is a thin-walled pipe of aluminium alloy, plywood or fiberglass. Tail boom made in the form of a light truss or stacked monocoque construction with hard balsa covering.
Modern modeling is different from the former, purely sports – this will not argue. The vast majority of adherents of the above-mentioned Hobbies is building models, not related to the competition. First, as it is abroad, a similar situation now exists in Russia.
The model with the air screw 2.5 cm grade3 designed and manufactured in a self-similar circle of Penza city station of young technicians. It is inherent excellent ride quality, stability and reliability of running. At the VI all-Union winter competitions, this model has a top speed 171,428 km/h and won first place.
In 1966, the Commission on space models of the International aeronautical Federation (FAI) has developed a code of sport in which raketoplana divided into four classes and assigned a so-called “bird” names “Sparrow”, “swift”, “eagle” and “Condor”. On the amended in 1975 and 1989 the FAI code partition models raketoplana into categories and classes depending on the total impulse of the engine and the starting mass was clarified requirements for each category, classes are five, and since 2001 to six. Today we will talk about the category of raketoplana S4 — models of gliders with the accelerator Category is subdivided into six classes the Most popular class S4A — promised.
