Designers snowmobiles know that linking directly to the crankshaft of the engine and the propeller is unprofitable: too high engine speed do not allow to use aredigital optimally. To reduce the propeller revolutions Amateur designers use chain gear, ploskostopie belts, banded V-belt transmission. You can meet the most reliable and compact single-stage gear reducers. As a rule, however, they are quite complicated. The most simple design managed to develop one of the enthusiastic Amateur “aerosanitary” from the city of Tchaikovsky, Perm region M. Psarev. On the processability of the mechanism at least tells TC that he “produced” a kind of microseries — was repeated at least five times. Today we introduce you to drawings and manufacturing technology of the gear.

The rapid slide on the icy surface of our homemade ice sailing ice boats, feathered wing-sail, in General determined the name of winter boat — “Blue bird”. It was built at the Central station of young technicians of the Moldavian SSR and was intended to teach novice boaters the art of managing sails in the winter.
To find a suitable engine for snowmobiles — the task is far from simple. Series motors in many aspects (in particular, power density) does not satisfy the Amateur designers. This makes certain enthusiasts to elect quite difficult, but the right way is to create motors own designs, using components and parts of serial.
With age the skeletal system, particularly the spine, is exposed to specific diseases. Begin to affect migrated younger overload, sports and work injuries. But at the same time and the habit of walking and by bike turns into a necessity. Thank you as with minimal cost to improve a simple road bike, making it more comfortable and “softer”. And I think I have successfully solved the problem of depreciation.
In 1959, the USSR Ministry of communications has ordered the design Bureau of the famous Builder of helicopters N. I. Kamov unusual for this size car — a snowmobile. Developers were tasked to create a vehicle that could provide postal services in remote in the winter areas of the North, Siberia, Kazakhstan and Far East.
Motorbike and car – the cars are different. First and foremost, by the level of comfort. Is it possible to combine the advantages of two-wheeled transport with the convenience of the car? It turns out that you can. And these two-wheeled machines – autoroller or motomobile sometimes meet on the streets. One of designs offer you to do it yourself.
Many readers were interested in the material “Migomobile — fantasy? Reality!” (1977, No. 11), tells about an unusual engine for transport — the flywheel developed by a group of young enthusiasts, members of the NTTM. To meet the wishes of readers to continue this topic, we begin today the publication of a series of articles about the transport of tomorrow. To keep this section we asked doctor of technical Sciences Professor N. V. Gulia.
Leafing through a binder of “Modeler” in 1975, I noticed an article in the No. 3 car, “rainbow,” built by young technicians from Tbilisi. Enjoy the car, I decided for their children to make such.
A quick key. 
The car was built in the days when I realized that the promised “reformers” two cars in exchange for vouchers, not only to me but also most Russians have never get. While we had to work more, and life became worse. On the salary they were paid very irregularly, could not buy a car. But it was necessary to survive. The hope remained only on the earth-mother — only she could help. But the suburban area was far outside the city, and get to it there is nothing.
