Hard to believe that everything is created by one person. Besides, not a graduate, but a simple fan design. As for the design and manufacture of completely heterogeneous machines required engineering knowledge in several fields of technology. Plus well equipped workshops and rich material stock.
Not without the help of the publication “Model construction” fashioned itself on the basis of the Minsk motorcycle universal cultivator. A good mechanical assistant turned, hard-working. The basis of it, of course, was circumcised (according to the advice of the journal) staff the motorcycle’s frame with mounted power unit and a two-stage chain transmission to the rear axle (from a sidecar of SZA). The handlebar is home-made, like the lining. A well blended with the design of the fuel tank — from “Verkhovyna-3”.

That may be so, but, unfortunately, the beginner quickly get tired of just plan, he wants higher and higher. And a struggle begins between the flight characteristics of the machine and the safety of the flight.
In the late 80-ies of the family of light vehicles with a mechanical drive (from motorcycles and snowmobiles to ALS) enriched by a new species ultralight aircraft, received the official (according to the classification of the FAI) the name of the paraglider. However, in colloquial speech it is often called a paramotor (PM), implying underneath the whole apparatus. The word itself was born out of the brand one of the European firms.

Strange trail remains for these sleds, rapidly descending from the mountain: the impression is that someone drove on one ski. And only bends on the side added short stroke of the second track. Unusual sports equipment, the construction of which is available to all lovers of breathtaking skiing the steepest slopes, has developed our reader from Magnitogorsk Sergei Chadin. Made of wood, the sleigh combines originality of design and ease of performance. For their manufacturing are required Board or thick plywood and a saw.
But not to throw out it! And involuntarily thought creeps in to make it a foldable frame. The same as, say, the “Kama”. I reviewed the literature on the subject (including the publication in “M-K” № 3, 1990) and left unsatisfied — too difficult was the recommended design. Had to develop my — more simple. Tried it and now offer to the readers.
Usually mention the proverbial fifth wheel. However, some automakers use a formula, reflected in the name of our material. They really believe the fourth wheel in the car superfluous. Judge for yourself: unlike a four-legged three-legged stool on an uneven base does not wobble (remember school: three points can be spend a plane, and thus only one). Therefore, trehalose frame will be more rigid and the car will be more lightweight and durable (and hence cheaper).
Mini makiki always use the boys great success. And for good reason! Small size, cost-effective, modern appearance, excellent performance — what more can you ask for? Maybe that’s why many of them roll up his sleeve so take tools. After all, if you try, you can do mokik, able to compete with serial two-wheeled machines. However, it is not very easy, but it’s worth it.
