In his letter to the editor a resident of the village of Blagoveschenka of Altai Krai V. N. Ermakov calls himself a regular and faithful reader of our magazine. However, Viktor’s being modest — he is not only a reader but also an active author, “Model construction”. For nearly 20 years Viktor regularly shares with readers his innovations and technical creativity. But his ardent and constant passion aerotekhnika, in particular snowmobiles and engines to them.

BUILDING A CAR
FROM THE ENGINE TO THE WHEELS The transmission from the engine to the wheels can be carried out on a homemade car in different ways. In practice, often such schemes:
SLED… IN A ROLL
In the folded, or rather— in the collapsed view, such a sledge is very transportable, you can even carry them under one arm, and in the car trunk will fit several sledges-rolls. Design features and shape such that the glide slope is smooth, without jumps and shaking, and the stability (due to low centre of gravity) is so great that to fall off that sled is almost impossible.CAR WITH MOTOR…
The author presented to the readers of cargo mini-mokik Nikolay Krasnov is a great lover and connoisseur motovelotehnika, especially vintage, although similar to modern cars treated with respect — he has not one good vintage motorcycle and when I have time, likes to ride on them.WHY FOOT CAR
In our days people are rapidly penetrates into the remotest corners of the earth, where not only no roads, but the leg of the Explorer never set foot. Surprisingly, in its long history, we are not a success to learn more of the sushi. And it carries in itself the untold riches that nature hides in forests, jungles, inaccessible cliffs.SAILING ROVER
Sailing has always been considered a true male. And not by accident: this sailor has the necessary power and speed of reaction, physical endurance, ability to keep calm in even the most difficult circumstances.“ROWING” DRIVE VELOMOBILE
Olympic games were held in Greece. I like venoconstrictor, pleased with the success of our riders on the track. And was impressed winning four rowers on academic Powerful boats, rowing together our guys and the work they have consistently connected the muscles of the legs, arms and back. Here is biotransport! Is it possible to apply this principle in the muscular drive of the velomobile to use this land purely machine as a rowing machine?THE CAR LEARNS TO SWIM
Among the huge variety of all-terrain vehicles of particular interest is the class of floating cars-amphibians. They are irreplaceable for geologists, exploration expeditions, the construction of gas and oil pipelines, for river service. And many automakers Amateur Amateur tourism — seek to create floating cars.BOARD AND SAIL

THE WIND IN THE CONTEXT OF The sail of the windsurfer is not the only element that produces thrust, but “the wheel” for manoeuvring. The air flow at the surface and water has a lower speed than the wind at a height of, say, three meters. Therefore, the load on the sail (corresponding speed) are proportional to the height from the water level and each overlying section of the sail will receive a certain twist in relation to the underlying (Fig. 1A).
BOARD AND SAIL
MANUFACTURER GUCHKOV Gucci rider is two arcs, glued wooden slats and the United front a metal band, framed with a soft rubber bumper. Shkotovo (rear) ends Guchkov have holes through which the sheet (rear) corner of the sail go to the ends of the nylon stoppers — sheets. The stopper is placed on each gig in a convenient pull-up or weakening of the Scots place — it allows on-the-go to increase or decrease “belly” of the sail.
