Snowmobile-stick “Bruins” with the engine IZH-P3. So, from the author of the popular among designers and fans of the series homemade snowmobile of the type of “Idea” — manufacturer’s description the latest and most powerful “stick insects” (snowmobile with caterpillar tracks made of wooden bars), nicknamed “the Bruins”.

Snowmobiles and tracked metamagic — “heritage” the magazine of the circle of technical creativity “modelist-Konstruktor”, in the village of Siwa Perm region. The first snowmobile created with your own hands R. G. Akhmetzyanov (pictured in the center rear). The machine is so attracted the attention of the local boys and has awakened in them the Read more…
The idea to build the Rover on low-pressure tires came to us with father after he was unable to rise to the snowmobile “Buran” to “Lunar glade” in Arkhyz. The design of the machine — type buggy, double, all-wheel drive. Frame — spatial with arc security, welded from tubes. Both the leading axle — back cars. Front axle is rigidly attached to the frame, and the suspension of the wheels — independent, transverse A-arm with clinohedrite dampers. Torque from the axle shafts is delivered to the wheels via CV joints. Rear suspension — dependent. Rear axle and its axle shaft just lengthened (track greater than 2 m). To the frame it is attached to the trailing arm with spring-hydraulic shock absorbers. Base — 2600 mm.
Kind the debut of this model yachts was held in the summer of 1981 at the Moscow city competition modelers. Attention athletes was attracted by the unusual hull shape: broad grancey nose, frames Charpy and a large ratio of width to draught. All this has not previously been used in sailing vessels of this class. The experiment was successful: the model showed excellent driving performance both on passing and on sharp courses.
Many RC modelers dream about. Those who decided to engage in this complicated class of models, usually start with gliders. After all, not everyone is lucky enough to find an experienced teacher who would help to develop not a flying machine, gave the opportunity for several days of joint exercises in the field to acquire the basic skills of piloting superkabuto. And the plane with working rudder and altitude to fly slower and more stable pilot error cause only the loss of a few tens of meters height. Finally, the gliders perfectly fulfilled such an important skill, as the automatic steering rotation regardless of where flies model: for the pilot or away from it.
It seems incredible that sparkling chrome valarelli, one of the many exhibits Central exhibition HTTM-82, manufactured by teenagers —
Conceiving a new microplane, any Modeler primarily decides which engine to put on it. One of the motors power is not enough, others too large, others strongly vibrate during operation. Many disadvantages of single-cylinder engine delivered a two-cylinder of the same displacement. They can be built on a variety of schemes: boxer, Y-shaped, inline. In some cases, if the Modeler is not very important weight, two normal “odnotrahniki” mounted on a common metal frame, connecting the shafts through the gear transmission. This allows to raise efficiency of the propeller by increasing its diameter at low speed.
In the first rank of the best projects presented by young technicians country in the Central exhibition NTTM-82, is “Rublis” — self-propelled plow-cultivator, or, as it is called, a plane. Built this machine students the eight-year school in the village of Ruda district of Liepaja Latvian SSR, the members of the circle of mechanization of agriculture.
In recent years, numerous sailing sports have added one: winter Windsurfing. At first, he spun off from the classic surfing as a way of year-round training: created a kind of simulator, which, according to enthusiasts, was to stay in shape during the “closed” waters, and also serve to teach beginners the basics of the art control boards. However, the training was so fascinating that soon had the idea to conduct a trial competition “sailing skiers”.
