Only two years have passed since that time, as the Federation of auto modeling sport of the USSR adopted a decision on the introduction of a new class of E-2. And this, in General, insignificant for the history of the development of the modeling period, a new class has gained popularity, is not inferior to any other self-similar. What is the secret of success?
When the boy, fascinated by the construction of models racing yachts for the first time the opportunity to try their hand at the most important stage in the competition? Of course, in the spring, at the start of the school Championships. But if a novice athlete has never appeared on the waters in terms of the competition, if he has no more experience of running sailing models, and knowledge on hydro – and aerodynamics and meteorology small — model traditional scheme it is doomed to failure.
“Wow, beautiful…” — that was the unanimous opinion of the participants about our high-speed cord models. After a short discussion, the boys made a “sentence” is a set of custom-making seem stamped out of plastic: “if we are…” oke We tried to explain that such models can build one that sets parcels elega/^tion speed is irrelevant and that make it much easier than any other… in Short, it ended up that I had to give details about the design, technology, construction and finishing of the new device. And then started flying again confirmed the unwritten law of aviation — a beautiful machine fly well!
Perhaps this mechanism could be the easiest family of his brethren: even to schoolchildren by force if necessary, to raise and move it. Light weight and simplicity of manufacture — these are the qualities of veloplugs attracted the attention of the visitors of the exhibition of creativity of young technicians, participants of all-Russia rally school forestry and friends of nature protection, held in the summer of 1986 in Leningrad.
Anyone who’s after a heavy snowfall had to clear sidewalks, alleys, parks, school hockey pitches, knows how difficult this job is. And involuntarily thought: “that would be Here some gear!”. And really, why not mechanize the work? No sooner said than done. So there is a compact mechanical “the janitor”, a description which we offer today readers.
In one of the episodes of the Central television can viewers met Amateur designer Oleg A. Ostapenko. We have become accustomed to the fact that “computers” introduces us to people whose technical work is always intriguing, surprising by the unexpected solution of various engineering problems. But they usually show one to two developments. Ostapenko did not just surprised, and amazed by the breadth of their Hobbies. He is the author of two original mini-tows, cross-country vehicle-amphibian, “forest” motorcycle and even discolored. In our “Panorama” (see “M-K” № 1, 1986) is a multiple of, we spoke about the success in the technical work of this amazing man. Today we offer readers acquainted with the description and drawings of one of the most popular designs O. Ostapenko — mini tug.
A few years ago I built my children a little micro-car. Called him “mouse”. Readers of “Modeller-designer” know him for publication in the June issue of the journal for 1980.
We offer our readers a model class S4B (raketoplan) designed by the famous Soviet athlete A. by Karapinar common aerodynamic configuration “duck”. She translates from planning mode to parauterine (forced landing) due to the deviation partneremployees stabilizer in the vertical position.
Grind on a hand grater even a dozen carrots – consuming affair, and if you want to prepare food for Pets to shred large quantities of vegetables, fruits? I came out with a simple electric grater. Used motor power of about 200 watts, with a rated shaft speed of 1400 rpm. (it will fit the engine from a household bench grinder; can be used three-phase asynchronous capacitor switching circuit in a single phase network.)
