When my grandson Grisha began to grow and stopped paying attention to previously favorite toys-rattles, the home began to notice that he started to show interest in different instruments and even mechanisms. Then I decided to make him a little electromobility-Quad, where in good weather you can ride on the street, and bad — Yves room. And not only that the child received pleasure from riding — mastering the driving skills he was introduced to technology, getting acquainted with its device.
“ELECTROPICA” FOR MY GRANDSON
In September 1931 under the Central Council osoaviahima of the USSR in the Bureau of air technology was organized by the Group of jet propulsion study (gird). Its first Chairman was the enthusiast of interplanetary flights, by F. A. Tsander. The group has launched a scientific advocacy of missile technology and was the initiator of the campaign, “the assault On the stratosphere”.
In the “M-K” have already talked about manual cultivator with fibronogen developed by members of the glee club VOIR (see “M-K”, 1976, No. 12). Further development of this design, in which muscular effort is minimized, was the tiller.
To run a series motor without special work can the Modeler of any skill level; not the high-speed engines. Because of the wide valve timing they sometimes play up all the short time allotted for training to start. That is why athletes try to use the starter, a mechanical device for the rotation shaft of the engine at startup.
Those who contain in the household livestock and poultry without grain reserves is not enough. Grain can be stored for a long time (in one of the magazines I read that in the tomb of a Pharaoh found the amphora with the wheat seeds were such that even wiseway). But that grain use for animal feed with greater benefit, must be pre-ground or at least crushed. But the grind, even large ones, unfortunately, under normal conditions for a long time can not be stored with it and the quality loses, and’t go rancid, and it infest some bugs, worms. So grinding is necessary in small amounts, and therefore quite often.
For industrial use trucks doing various capacities. As a General rule, plant as light-duty use, for transshipment of cargo between objects — medium-duty, and long distance (“long-range”) transport— powerful semitrailer tractors.
(SPEED CONTROL LINE MODEL CLASS 5.0 CM3). The name of the master of sports of international class Mykola Troneva from Leningrad familiar to automodellista. Since 1970, Nicolai permanent member of the national team. With his pattyboy model he has participated in many international meetings, not once occupied prize-winning places in the Championships. The General view was that the model Troneva differ
Letters a lot. One of them is to “brand” the forms of various enterprises and institutions, others on pieces of paper torn from a student notebook. But the questions are all about the same: the readers are interested in where, when and how you can get comprehensive information about gliders and hang gliding. We started in 1968 talking about a new kind of motorless flying has generated huge interest and gained the scope is truly inclusive. This, in our opinion, quite natural and not surprising: the level of technical training of young people is now high enough that even at home to build their own full-fledged glider. A shortage of necessary materials also does not stop enthusiasts of hang gliding. Difficulties in other: there is good, detailed and accurate drawings, which could produce details of the glider and the lack of experience and technological skills very often negates the attempt to make a dome (the sail). Reach extremes. In a letter to the seventh-grader Vladimir Nikitin of Sumy region photography barefoot boys. He flies with a small hill on a hang glider, made of spruce and covered with pieces of old red slogan.
Rigging centerboard yacht “salute” consists of two sails (mainsail and headsail), mast, standing and running rigging.
