Winter in our Northern lands long. Roads are not so thick, and those on time do not have time to remove snow from. It turns out that no trails of cars people here do not easy, moreover, often have to travel entirely off-road (e.g. forest wood) — recorded directly on virgin soil. However, the acquisition of a snowmobile, not everyone can afford, even the not-so-expensive—simple. So we have those who are able to make a machine with their hands, designing it according to your project under those parts that the craftsman. The snowmobile, which, the story goes, I was not the first (see “modelist-Konstruktor” No. 11 for 2004).

Lately in the aviation modeling widespread flying models, radio controlled, including helicopters. For the first time such a model was demonstrated in 1959 at the all-Union competition of S. Vorobyov. To control the flight he applied the principle of changing the alignment of the apparatus. After a year in the championship, in the background, a helicopter appeared Borisov with an aerodynamic rotor drive. In 1964, at a match meeting of the athletes of Moscow and Leningrad, he introduced the concept of B. Yuriev new model with tail rotor. However, the car was “raw” and, unfortunately, remained unfinished.
The best Amateur-built glider, took part in the competition “Dombai tops” in 1978, was named “Sokol-2”. Its Creator — Leningrad master of sports V. D. Mikhailov, a renowned specialist in the design and making of yacht sails. So it is understandable his desire to use when constructing the glider, the latest achievements in the field of sailing. As a result, the quality of the dome “Sokol-2” had no equal among the devices flying over the Caucasian peaks.
The fuselage of modern rezinomotornaya model aircraft usually consists of two parts: the power (it houses the rubber motor, is attached to the lug screw, wing) and the tail boom carrying the tail surfaces. The power part usually is a thin-walled pipe of aluminium alloy, plywood or fiberglass. Tail boom made in the form of a light truss or stacked monocoque construction with hard balsa covering.
Modern modeling is different from the former, purely sports – this will not argue. The vast majority of adherents of the above-mentioned Hobbies is building models, not related to the competition. First, as it is abroad, a similar situation now exists in Russia.
Many accidents occur due to technical reasons, including due to faults of the brake system of the vehicle. One of the indicators of the effectiveness of this system is the braking distance, which for different categories of vehicles is regulated by state standard. Determined he may be on a special stand.
Central to the exhibition NTTM-78, dedicated to the XVIII Congress of the Komsomol, and the 60th anniversary of the Komsomol, very popular among the visitors enjoyed the section “Eureka”, in which he demonstrated unusual vehicles created by Amateur designers. Wheeled-tracked all-terrain vehicle “Arctic”, built as an electrician from Rybinsk Valery Medvedev, was one of those cars that arrived in Moscow on VDNH USSR “his way.” Yes, it was not a model but a live working machine, figuratively, “discontinued operation” in the household of his Creator. Summer and winter, heat and cold, hunting and fishing, just outside the city with your family or on urgent business drives this original machine designer. Already more than fifty thousand kilometers was “Polar”. The mileage is respectable, even for production vehicles.
Snow scooter “the little humpbacked Horse” — advanced single track sled with steering from the mountains for skiing on-piste slalom or downhill. In different countries such sleds have different names: “snow bike”, “snow horse”, “ski-Bob”, “ski-Doo” (“the snow flea”). And they are made variously depending on the purpose and conditions of operation.
Was close on the streets of big cities in many countries. Cars almost RUB against each other. The speed of the traffic flow often barely exceeds walking speed. But just watch — in a multi-bed machine sitting often only one driver, in the best case in society only passenger. The other places are empty. Then, maybe, you need to reduce the machine dimensions to one double-minicar, freeing up additional space on the streets thousands more like them?
About the craftsmen of the rural settlement of the Highlands of the Yaroslavl region, I had occasion to write more than once, and what a surprise it was that the reserves were not yet exhausted. With the local game warden Jevgenijs Picolinium relationship work immediately. It was felt that man can not sit idle. Every year, a new car, be it a tractor, ATV or buggy.
