A familiar winter TV story is the rescue of ice-fishing enthusiasts from a drifting ice floe. Almost every year we are shown how emergency services specialists on helicopters, boats, or all-terrain vehicles save unlucky anglers. Such incidents are not uncommon on the country’s freezing bodies of water. Moreover, anglers often drive out onto the ice Read more…
A folding bicycle is nothing surprising today. However, even when folded, its dimensions are not that small, and storing it at home — let alone carrying it on a bus or tram — is not always convenient. I set out to develop a convenient folding bicycle with the smallest possible folded dimensions. I wanted it Read more…
The author of the article and the creator of the all-terrain vehicle discussed here is Boris Nikolayevich Ryzhov — a long-time acquaintance of our magazine’s readers. Photographs of the machines he built (a tracked and a six-wheeled all-terrain vehicle) were published in the magazine as early as 1990 (No. 7). But the desire to create Read more…
For those who live near water, a boat is as necessary as a motorcycle or car is for others. Of course, experienced amateur shipbuilders are unlikely to settle for the little craft we want to offer your attention, but for beginners in boatbuilding this boat design is just the thing. It is simple, technologically straightforward, Read more…
One timber beam and a canvas bag (a bag with a round bottom) measuring 550×1400×1450 and 250×1400 mm — that is what this svertboat turns into if you take it apart and pack it for transport. Compactness was achieved by making the hull three-section. Each section can nest inside another, like the familiar “matryoshka” dolls. Read more…
The magazine “Modelist-Konstruktor” has already described motor winches more than once — fascinating soil-cultivation mechanisms that have been gaining increasing popularity among amateur designers in recent years. And indeed, the merits of this excellent device are indisputable. The point is that a winch (by the way, one of the oldest mechanisms in the history of Read more…
Readers of the magazine “Modelist-Konstruktor” are offered a simple wheel-and-ski snowmobile designed for travel along snow-covered country roads and even open snowfields. The snowmobile is three-point, with two rear driving pneumatics and one steerable ski at the front. Compared with other machines of this type, the snowmobile’s design is extremely simple, which makes it possible Read more…
For all their advantages, an inflatable boat of any design has the same common drawbacks: short oars, a tortoise-like pace, and poor maneuverability. We managed to get rid of all of them at once by adapting our boat “Nyrk-4” for sailing: with a sail it became both faster and more responsive. And the additional equipment Read more…
Readers of our magazine are already familiar with the best examples of technical creativity by S.P. KOROVIN, a designer from Kumertau (Bashkortostan). In “Photo Panorama” (see “Modelist-Konstruktor” No. 1’2000), his most famous designs were presented: the “Visit” aircraft, a children’s car, the seven-seat “Orbita-1500” car, and a jet ski (personal watercraft). Later, readers appreciated another Read more…
How far can a person travel by pushing off the ground just once? If it is one step — on average less than a metre. If you build up speed and push harder, you can jump about four or five metres. So imagine our surprise when a modest, no longer young man walked into the Read more…
