Raketoplana this scheme, the athletes received the name “Moscow” in the building today, everywhere that speaks about its high aerodynamic qualities and reliability. However, each rocketmodeler trying to bring in design and something different, getting this sometimes with interesting results. It was developed a model athlete from the Altai city of Biisk Alexander Puzikov. Based on the “Moscow” scheme, he increased the wingspan rocket glider and the length of its fuselage. And, as shown starts at the Russian Championship of 1996 for model rockets, the innovation has justified itself.
The proposed boiler is designed for heating cold water (temperature up to 60° C) in apartments with Central or local water supply. Facilities associated with the operation of the boiler, no doubt, be appreciated by every hostess.
Amateur Designers often used in the transmissions of their cars, the chain transmission. And sometimes faced here what problem: for the calculated gear ratio chain couples find it difficult to choose ready-made sprocket with the desired number of teeth. But them it is possible to make yourself using the jig, assembled on the basis of the gear closest to the desired amount. Suppose you need a sprocket with 26 teeth and pitch of 19,05 mm. will Select the gear with the same or similar number of teeth. For example, 27. (In this case, the gear ratio will change slightly by 4%.) The gear is hardened, has a thickness of 19 mm and a bore diameter of 20 mm.
Many models can be made to forgotten the method, by squeezing the sheet metal. Extortion is used for any thin-walled parts (e.g. fairings, cowlings, shrouds, wings, wheels, and similar). Often they are made of brass or aluminum alloys. The material is pre-annealed with a pair of scissors and cut the workpiece with considerable allowances. The tools serve as a mandrel, anvil and various hammers. The process of knockout s is the stretching of the material when its thickness decreases, and in the sediment, which implies an increase of the thickness. 
The winter of 1940 was severe and snowy. So when in late February the first two experienced thirty went to the unprecedented thousands of kilometres of mileage on the route Kharkiv — Moscow, he became perhaps the most rigorous and impartial examiner and for new machines and their designers and producers. By the way, one of the tanks was himself Mikhail I. Koshkin, head of while the Department designed the T-34.
I suggest the owners of motorcycles IZH a simple design of the towing device is constructed as a single unit with a mounting bracket, a spare wheel. Despite the fact that between the sidecar and the bike is not too much space, “reserve” does not interfere with passengers on the rear seat.
