Do I have to mug for the second year, two seventh graders. Like everyone else, they began with rezinomotornaya contour of the car. In fact, the tenacity with which even unskilled hands, they grind parts, with some passion launched his first microwaveability, it became clear — will of the good guys. Soon they built from kits and simple racing models with internal combustion engines. Gradually became their skillful hands, the children learned to treat different materials, began to feel that is not enough running mikromotorchika and how to troubleshoot to race “whiz” down the left the entire distance along the path of the track.THE MAIN THING IS TO KEEP SPEED
Do I have to mug for the second year, two seventh graders. Like everyone else, they began with rezinomotornaya contour of the car. In fact, the tenacity with which even unskilled hands, they grind parts, with some passion launched his first microwaveability, it became clear — will of the good guys. Soon they built from kits and simple racing models with internal combustion engines.

“Shortly before the New year left to drink” — whether in jest, whether seriously says on the website www.snowmobile.ru acting under the nickname (alias) Canosa Alexander Zaozerskaya from the city of Totma in the Vologda region. During a multi-day holidays came across the magazine “modelist-Konstruktor” No. 11 for 1991. It was the publication of a homemade crawler snowmobile “Idea-2”. Also decided to try to build a “snezhik”, good experience of working with iron were for his workshop all woodworking machines made with their own hands.
There is an expression: “the Best is the enemy of good.” It remains true, however not always. Any Modeler familiar with one of the standard domestic compression motors — KMD-2,5. Although it is designed for racing model aircraft, it is successfully used and air “fighters”, only pilots and beginners. 
Well known to our guys managed sledge “Chuk and GEK” called snegokat because it is meant for use only on the slopes of the snow hills. Rapidly — only the wind whistles! — rushing snow-cats down on their three skis. Front controlled, allows you to change direction to avoid obstacles. But as soon as the slope of the end — sled, Proskuriv some more inertia, will stop: on level ground they will not leave. Then on the old proverb: love to ride — love and sleigh to haul! The rope and the slide. But what is it? The distance seemed “Chuk and GEK”, which, having fallen down with the same speed continues to race on a flat snow field. Here the rider was a teenager deploys a cool scooter, and surprisingly others behind him opened hinged to the frame a motor and caterpillar. This is already a snowmobile. And it was built Moskvich Yu. Tereschenko.
Is it possible nowadays to build your own plane? Tver aircraft enthusiasts Eugene Ignatiev, Yuri Gulak and Alexander Abramov answered this question in the affirmative, creating a winged single machine, later named “Argo-02”. The plane was successful: successfully flew on all-Union competitions, was the first winner of regional review-competition of Amateur aircraft in Yaroslavl. The secret to increased popularity of “Argo” Amateur aviators not the designer or the technological refinements of designers, but rather – their traditionalism. The designers managed to achieve a successful combination of waste over many decades of design methods of wooden cars of the 1920-ies and 1930-ies and modern aerodynamic calculations of aircraft of this class. This is perhaps one of the main advantages of the aircraft: its production does not require advanced plastics and composites, rental of high-strength metals and synthetic fabric with the pine timber, some plywood, fabric and enamel.
Unlike analog, in the boat “Victoria” from St. Petersburg to create an air cushion and propulsive forces (thrust) uses an air screw. This allows the machine to move using both static and dynamic air cushion. The transition from mode to mode is performed by changing speeds.
The search for the optimal design of passenger car is a matter of time. The solution to this problem and doing powerful design Bureau leading automotive companies and associations, and Amateur designers. Our magazine has repeatedly appealed to the topic. Today we offer enthusiasts autocostruzione two promising development of the Moscow engineers P. Zak and E. Rudyk.
Recalling the history of the snowmobile, realized how long ago began my fascination with construction equipment. Even in his youth (and now I’m already retired) received the specialty of a locksmith and mastered on his own welding business, other specialty Metalworkers. But knowledge of design, to tell the truth, “boast” could not, and to learn there was no place. Built on a whim any “grindaholik” on wheels and tracks went on them and on the road and in the snow, but neither the reliability nor beauty.
“Silver” the world championship of 1981, the same year the first place among the strongest athletes of the USSR — it is the best feature of the scheme boat built by the master of sports of the international class, the repeated champion and the champion of the USSR and the world by A. Tupikina. A similar model was helped by his colleague Vladimir Dovzhenko to be among the winners of the USSR championship in 1982 and set a new record in class-1.
What boats will not meet the competition. Some amaze with perfection of outline and finish, it seems that it is better not come up, ke will. Others want to pick up and “bring to mind”. But this, though done really skillfully, carefully and conscientiously, initially produces a strange impression. A small case with a nearly rectangular frames, a transverse rail with ridiculously small floats. Whether clumsy trimaran, whether the model is a replica…
