Conceiving a new microplane, any Modeler primarily decides which engine to put on it. One of the motors power is not enough, others too large, others strongly vibrate during operation. Many disadvantages of single-cylinder engine delivered a two-cylinder of the same displacement. They can be built on a variety of schemes: boxer, Y-shaped, inline. In some cases, if the Modeler is not very important weight, two normal “odnotrahniki” mounted on a common metal frame, connecting the shafts through the gear transmission. This allows to raise efficiency of the propeller by increasing its diameter at low speed.OF THE TWO “COMETS”

In the first rank of the best projects presented by young technicians country in the Central exhibition NTTM-82, is “Rublis” — self-propelled plow-cultivator, or, as it is called, a plane. Built this machine students the eight-year school in the village of Ruda district of Liepaja Latvian SSR, the members of the circle of mechanization of agriculture.

In recent years, numerous sailing sports have added one: winter Windsurfing. At first, he spun off from the classic surfing as a way of year-round training: created a kind of simulator, which, according to enthusiasts, was to stay in shape during the “closed” waters, and also serve to teach beginners the basics of the art control boards. However, the training was so fascinating that soon had the idea to conduct a trial competition “sailing skiers”.
Did not have time to be approved and become a massive new and exciting sport of hang gliding enthusiasts as it took to lay another area in the technical work associated with designing balancing aircraft, — the construction of trikes.
Ecology and environmental protection are becoming increasingly relevant topics in the world. Constantly more stringent requirements for emissions of harmful substances by vehicles. Therefore, the major manufacturers are developing and start producing electric and hybrid cars. To reach these developments and to our country.
On the Fifth competition of the European championship miniature rocketmodel class S1B master of sports of the USSR Yury Soldatov brought its designer, the title of champion of Europe 1981. She rose to a height of 1046 metres! Design model developed by a team under the leadership of V. Minakova. Thorough testing of the technology, the reasonableness of the scheme made the aircraft a kind of benchmark: with missiles of this type were made by all members of the Soviet team that won first place in the championship.
Creative finds of young technicians, the successful resolution of their original design objectives our magazine told repeatedly. Examples of research innovation activities of school today can cause a lot. However, in order for the movement of young innovators has become more widespread and effective, they need to properly and skillfully manage. This is often write to our office, heads of groups, clubs, stations of young technicians, enthusiasts, social activists, the immediate organizers of technical creativity of children and adolescents.
Ground treatment — the work is physically difficult. To facilitate the farmers-gardeners and used mini tractors and tillers. I thought that it is best for such work fits motoliberty, and produced his own. The power unit of motoliberty from scooter “Vyatka-Electron”. It is quite powerful and so good that supplied with standard air cooling system.
It would seem, what new it is possible to invent models of air combat! Undoubtedly, these microstrobili today meet all the requirements of transient encounters over the track. No wonder even top athletes can be heard that the best equipment they are not necessary, it’s just a systematic preparation for the training athlete.
