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.
Description of the micro-car, only “Viking”, built by engineer S. P. Zack (“M-K” № 1, 1975), still attracts lovers autocostruzione. The stream of letters continues. Readers interested in the operating experience of “Minimax”, the possibility of its modification under the new requirements of traffic police. They asked to talk also about the individual elements of a design peculiar to the wagon layout, on the further development of this scheme. The most often repeated questions are answered by the Builder of the machine.
As you know, aeromodelling motor “rainbow-7)” is a typical “Kalinka”. But a few additional parts easily turn it into a compression engine with a displacement of 7.0 cm3.
Said to be good the model airplane itself teaches us to govern ourselves. Especially valuable is her property for beginners korovikov. However, apart from flight, training models required: maximum ease of fabrication and strength. We offer our readers two successful design for the initial “school” for learning the basics of flight complex. These models-coaches can help young athletes become faster first-class masters.
“Ice bird” called athletes Buer-“vosjmimetrovaya” for his high speed and the ease with which it allows you to make turns and maneuver. Especially for “sense the wind”: the throttle response, as told to motorists. Finally, the ability to immediately respond to any request of the steering: “good message” — would have celebrated horsemen. This is true, because his “power to weight ratio” — the ratio of the area of the sail to the total weight of the glider is higher than other types. But still Berestov attracts you to a free class: if the rest are monotypes, and must exactly match your standard, there are great opportunities for creativity, experiment.
