The constructor of this model class SA Maxim Shekhvatov, a schoolboy from the city of Elektrostal (the Moscow region) and the champion of Russia 2001 in two classes of sports rockets SA and S4A. His model made on the so-called paper technology. Fairing glue on the metal mandrel of the five paper petals. The mandrel before it is heated and smeared with mastic “Edelvays”. After cooling of the postmark on the mandrel is applied to the petals, smeared with white glue, and smooth to prevent wrinkles.MODEL-THE WINNER

This machine is created by a Hadith Shagalievich Shatalin sons from the village Sermenevo. Engine — diesel D-37 electrical equipment — from tractors T-40, axles with wheels from GAZ-66, from him and the frame, but it’s a bit narrowed and strengthened. Bridges shortened and fixed to the frame rigidly. Transmission: clutch basket, gear shift —from ZIL. Steering — the tractor “Belarus”, cabin — tractor T-4, fuel tank — from DT-75.
Where the number of technical groups is relatively small — in schools. Pioneer houses at the Hoo, in children’s sectors of trade — Union clubs and where there are difficulties with the premises, can be equipped multipurpose educational laboratory, easily convertible to exchangeable classes of circles of air, road and ship modelling.
In Amateur radio practice, there are situations when 9-volt DC source you need to obtain 12, and then a higher output voltage. Bail in such cases can I designed a compact transformerless adapter. Made on the basis of two or three common chips and four transistors, it will allow first to improve the initial voltage of approximately 17 V, and then to output the desired 12 V. And stable.
Recently there is a rapid displacement of the cassettes compact discs (CD). Among the reasons for this and the continuous increase of requirements to quality of sound reproduction and virtually unlimited service life “compacts”, and reducing the value gap between them and the tape carriers of audio information. So, in June 2001, the market price of one CD with modern recordings is consistent with a cost a half to two cassettes. However, equipment to play music CDs is still very expensive and not everyone can afford its purchase.
Under the heading “advice to the Modeler” magazine “modelist-Konstruktor” No. 11 ’01 published material on how to adapt the radios from cheap toy cars of Chinese production to the remote control equipment, which is lacking in the circles of children’s technical creativity. Penetrating the essence of the proposed technical solutions, I came to the conclusion that the chip KY011 encoder base of the transmitter with a more efficient application allows you to enter two more commands through the use of the 1st and 6th “back-up” pulses.
The proposed model missiles S3B allowed its Creator Tarasov from Chelyabinsk to become a winner of four Cup competitions S. P. Korolev. Moreover, it is universal: it can serve class Ѕ6В.
This car rolled off the Assembly line of the Gorky automobile plant, sixty-six years ago — in March 1936, succeeding produced there the first mass Soviet passenger car GAZ-A. the Basis of the new car was the Ford V8, which replaced the suspension (instead of the transverse springs Gorky made a lateral). The motor “m” used from the previous model, and after upgrading he developed a power of 50 HP, driving the car to 105 km/h.
So we said in the editorial, having received an article by our correspondent from Donetsk and came almost simultaneously with the letter of the head of the shipbuilding laboratory of the Donetsk syut Valentine Boikova. Hello, hydrocutting! We were looking forward to reader responses on the first article about hydrocort, publication of which began in this magazine in 1969.
