To create a device is simple, inexpensive to perform and at the same time with high performance — such is the aim of gliders. We offer our readers the description is very promising glider “Albatros” open class, created by Moscow engineer A. Z. by rabanim in early 1978. This device has been widely tested and has a high aerodynamic qualities. From other phones open class “Albatross” stands simple design (all tube frame straight), in combination with precise profiling of the dome, which provides pre-curved armor combined type (front — hard, back — elastic). The frame of the Albatross allows you to apply domes of different shapes and size without any alterations and additional adjustments.
Readers of “M-K” have already had the opportunity to meet with a student design Bureau Mari Polytechnic Institute (see No. 8, 1977). This team is many years engaged in the original design of snowmobiles, including many snowmobiles amphibians. During the time elapsed after the publication at SKB have developed two more such machines.
Like many readers of “Modeller-designer”, my Hobbies are designing and making homemade equipment is therefore with special interest I read in the journal of machines and mechanisms created by craftsmen.
Spearfishing in waters with complex bottom relief and limited transparency of water has its own characteristics: no time to restore the gun, nowhere to maneuver. Rifle, currently available in the sale, for such conditions uncomfortable. Which is preferable underwater guns. Of the known types of such weapons is most suitable — capsule. Their main advantage is that when fired the harpoon at the impulse of several hundred kilograms, in contrast to the guns of other systems where the force on the harpoon does not exceed tens of kilograms. Accordingly vary the speed of the harpoon. The advantages of cap and ball pistols can be attributed to the ease of loading.
The club “Romantic” from the city of Krasnoyarsk our readers know of the recent publication (“M-K”, 1979, No. 4).

Fulfilling readers ‘ wishes, we asked the head of the section of Amateur sports autostructure V. A. Hassan to talk about one of the most interesting cars.
That recumbent healthy, I think, nobody will argue. Well, for fans of technical creativity it doubly useful as it allows you to gain invaluable experience before the greater constructions. Recumbent, about which speech will go, was designed and manufactured in the workshop of young technicians (syt) of our city, together with members of the group. I must say that the idea of its creation have arisen much earlier, but because the materials and most of the parts (particularly wheels) have prepared himself, at his own expense. However, the wheels and the materials are mostly picked up from an abandoned Bicycle, so that the cost was not so great.
To fly like a bird, the strength of your muscles, very tempting; dreamed about it many of our ancestors. Already in the XV century, when on flights in the modern sense could not even dream of such a machine designed by Leonardo da Vinci. Unfortunately, he was not able to implement their ideas. And only today, after five centuries, people have achieved the first real success.
