For many school model aircraft clubs create room flying models is the only available form of modeling. Judge for yourself: the season of the competition model, as a rule, coincides with summer vacation, and autumn, winter and spring start model is quite difficult weather conditions. At the same time any sports or Assembly hall is a great arena for competition in the class of low-speed models with resi-nomotion. The design of the latter — the process is no less fascinating.FLYING UNDER THE ROOF

In Russia the Banya is not only a place of bathing, “hospital”, a place of rest, but part of the culture. Well, about the garage and say no is the individual a man’s world!

Since the emergence of tanks as a kind of weapon in their design a special mark was put “duel armor and shells”. By the end of the Second world war, showed a certain balance. One of the original criteria in the development of new war machines was the requirement that the tank armor is not penetrated by armor-piercing projectiles of his own gun. In this approach, and were all post-war tanks of the so-called first generation.
This publication, we continue the story about the history of one of the categories in the rocket modeling – S4. It includes four classes of models raketoplana (model glider with the accelerator). Sports (champion) class is the SHA with the momentum of the engine to 2.5 n·s.
A Russian passenger car GAZ M20 “Pobeda”. This particularly civilian car was designed during the great Patriotic war. For a future peaceful life, she produced and assembled at the factory, almost completely destroyed by Nazi bombers and nevertheless producing light tanks T-60 and T-70 self-propelled guns SU-76M and armored cars BA-64. Finally, this machine was created by people who in this difficult time found the strength to work on the post-war future, then seemed incredibly far away…

In the design business, like any other form of creativity, a person often have to take an unpaved path. This path is always difficult; it is only one who is fluent in the ways, methods and means of design creativity.
His first flight of the day anti-tank helicopter the Ka-50 made in 1982. When designing the machine was seen as an alternative to the American helicopter Ah-64 “Apache”, and the testing process successfully passed the contest in which his opponent was an attack helicopter Mi-28.
