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.

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 1 mm with a length of about 2 m. the Model flies well indoors and outdoors.
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.
Aeromodelling laboratory at the club of young technicians Kakhovka plant of concrete products of 50 years of the USSR created three years ago. Began to engage in a small room of an ordinary house, and now CUT has a spacious, bright room in the new Palace of culture “Improver”, has all the necessary equipment, machines, tools. Here is the first in Kherson region the track, which now hosts all regional competitions on aviamodelling sports. Last year in Kakhovka took place championship of Ukraine on kordovy the aircraft.
Svobodnaya radio control model airplanes, gliders and helicopters is currently being implemented with the help of tiny transmitters that have levers or buttons to apply for the model of the desired commands. All of these devices have nothing to do with the controls of a real aircraft and need to develop specific skills and reactions. This means that the experience of control appears to be useless in the future, say, in the case of the transition has mastered them to the training flights in a glider, and especially on the plane.
Readers of radio-controlled model copy of the missile and aircraft interceptor BI-1, the parameters of which correspond to rocket gliders S8F Recall that this flying class combines the model with a mass of 500 g with engines of 40 — 80 N.with. Among the requirements for models of this class — the prohibition of splitting the model into two or more parts (including the engine after the trigger should remain in the container). Besides the active part of the flight (take-off) should be straightforward — ascending spiral and loop invalid. Maximum measuring time of flight of the models in this class is 300 seconds.
