What should be the car for summer camp? Some not without reason consider that the creation of autoconstructor mug here is futile, since class time is extremely limited. But this, we think, is wrong: you only need to choose an object to design.
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.

The kids loved the kid Carlson, and not the last role in this played the “technical equipment” lover of raspberry jam — it is famous for the motor with the button on his belly…
Design and manufacture of midget cars is one of the popular directions of technical creativity. This can be judged by the growing number of automodular presented at various technical exhibitions. Unfortunately, many of the infantile groups you have to “Torito” own way, repeating the mistakes of predecessors, not taking advantage of their good experience. In today’s post attempts to summarize the experience of autocostruzione in the laboratory of experimental modeling of the club of young technicians of the Siberian branch of the USSR Academy of Sciences.
In No. 10 for the year 2007 was published material designer homebrew A. Knyazeva from the city of Rasskazovo of the Tambov area made them a few snowmobiles.
