He was born and I grew up in that land of mother Russia, where the land most of the year is under a thick cover of snow, a reason those places is considered the birthplace of Santa Claus. Perhaps that is why along with General interest in engineering of particular interest to me has always evoked the snowmobile machine. To have such was my childhood dream come true. When I grew up and learned to do many things with their hands, decided to make its design. By the time I’ve not only studied the device snowmobile vehicles, but was able to critically evaluate the advantages and disadvantages of this technique.

I want to share my production version of the arcs security, which set me on a motorcycle “Java” and for more than a year of reliable service. Friends motorcyclists interested in their design: shot size, shape, etc. So I decided to offer them to the readers of the magazine.
Model rotocut of the champion of Russia 2003 G. A. Reshetnikova — further improvement of “sergievskoe” scheme, developed in tstt “Youth” under the leadership of the deserved trainer of Russia L. O. Krasnov. This variant slightly increased the angle “V” pendant of the blades (12°) and has an additional corner of the “V” at the point of kink (folding), which promotes sustainable autorotation.
Under this title that has become like a calling card, we publish the latest development of the professional engineer and Amateur inventor of the Bicycle (but not only) from the village of Inozemtsevo Galvanoscope district of the Stavropol territory V. M. Gavrilov. This time he invites our readers to design one-wheel trailer — truck.
At the start, during the competition, when all the machines are in several rows lined up in front of the white line, this card is easy to get lost among the brethren. The same wheel, the usual sight for the seat and steering wheel… That’s just the engine it does not emit deafening sounds of firing, and working with a barely audible hum. The reason is simple — on the map instead of the internal combustion engine is an electric motor, powered by the familiar lead battery…
…A quiet summer evening over the water area of klaipėda seaport appeared strange flying machine: its wings were similar to a lattice, and the pilot was housed in a tiny cabin, reminiscent of a sidecar for the motorcycle, It was a new hydroplane “Duck” (Fig. 1), design B. Yu Oscines — the latter option already described in No. 4, 1975 BRO-16.
Becoming a pensioner, was engaged in the breeding of the nutria (swamp beavers, or coypu) and saw how it is a profitable business. With the low maintenance costs of these herbivores and also very unpretentious animals not only get delicious meat (an average of 2-3 kg of each species), no way inferior to the rabbit, nutritional value and dietary properties, but also (most importantly!) valuable fur, on the strength approaching a mink or a Fox, and wear exceeding ten “fur” of the Bunny.
For the study of near-earth space in the United States since 1948, began to build rockets “Aerobe”. To date released a large number of their modifications. A two-stage rocket “Aerobi 100”, the description and drawings which we published, are very useful for modeling. It is easy to manufacture and available to the modelers for the second year of study. Its flight is quite stable and shows good sports results. It is possible to participate in competitions of any rank.
Chassis model paddle steamer. Model river paddle steamer look so advantageous as compared with the model of a modern airliner, as a large-scale replica of a steam locomotive railway locomotive attractive copies of our days. A water suspension model “Kolesnik” the nineteenth century, looks amazing – plenty of add-ons “mast, pipe, efficient things – all this creates a mouthwatering flavor century couple.
Designing patterns, usually always takes place in several stages. It is almost impossible to make a decent model, once having passed a way from calculation and drawing to stitched wing Mylar film. Typically, this is only the first step in creating the model. The following will be the flyby of the model and its numerous improvements. And only when to improve the model through modifications, it will be impossible, on paper, a second version of the model, which absorbed all the best from the first and supplemented by all those. it was impossible to implement in the first version, with improvements. This is followed by overflights and…
