“Dear edition! I have been modeling, build kordovye-models, flight a big request To you — please let us know what new model airplane engines went on sale in 1973”. V. Vasiliev. Chita oblast.
Kordovye contour-models have always been attracted to model airplanes. To create them, unlike the full copies, takes less time, and aircraft modeling experience needed for this not so great. As a prototype for contour models are most often fighters — these machines are spectacular in flight, they are easily recognized not only modelers, but also the audience. Moreover, in the air, the fuselage does not look flat.
If the aerial part of the German operation for the invasion of Crete in may 1940, no doubt, was an outstanding achievement and entered the history of the art of war, its Maritime component looked just pathetic. The so-called “First light convoy”, intended to capture the airfield at Maleme, consisted of two dozen commandeered the Greeks of motor boats and small coasting boats to the full loaded troops, weapons and ammunition. The only warship, which was assigned to protect the caravan from the enemy fleet, was a small Italian torpedo boat “Lupo” commanded by captain 2 rank, Francesco Mimbelli.
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.
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.
If you have to saw a certain number of wooden rods with a strictly perpendicular end faces, it is advisable to pre-make auxiliary guiding means conductor. It is necessary to take flexible sheet metal (e.g. sheet steel) and any way you cut it narrow slit. Enough now to wrap a sawn sheet rod and the Read more…
