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.

The one who animaetsya room with model airplanes knows what a difficult job the installation of the stretch marks. But they stiffen the easiest transparent planes, and even a small error in the tension lead to distortion of the shape of the wings. The work is delicate, painstaking and long. And if you say that you pereustanovit model (you need to remove the “wood” braces) to bring it into working condition for 2-3 minutes, and even in terms of competition, it will seem unreal to you. However, after reviewing the proposed method, you will see that it is quite possible.
Any of us can certainly, without hesitation, to list a lot of famous planes, cars and ships, inscribed your page in history of development of military and civilian equipment. However, it turns out, the model a scheme could play a significant role. Let not the history of all the equipment, and only one type of technical sport.
The kid from the first start push-rod started the engine, and early test-in. The engine revs, causing the car faster and faster to run on the track. Here are the included machine-cut timing a run of eight laps of the race, which is determined by the speed of the model. One lap to another… But it is! The impression is that someone hung on the rear wheels of the machine and slows down her run. Smooth, easy sound debugged in training “engine” was replaced by strained, jagged roar. Of course, the speed shown “shell” is too small.
In his hands standing on the bridge of a schoolboy elegant model powerboats. The boy winked one eye, as if before the shot. Finally, the wind has abated a little — it is possible to produce a model. Raising astern low backwash water, the boat went to the goal. After fifty meters posed a number of buoys, medium form the gate width of two meters. It is best to get it in them — a rating in the highest. With a frozen heart, waiting for the young athlete how to behave microcode. There is a hit! Even the rising wind and waves did not prevent him to enter into the Central gate.
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.
“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.
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.
