In otpetie from the existing is a stationary device, using which even the youngest artist can easily and help hold the nail (particularly when the jig saw with the Read more…
The appearance on the competition models of sailing catamarans and trimarans was the natural result of the development of a very interesting class of ship models — radio-controlled yachts. First I gotorussia was built in our country in 1974 almost simultaneously by three athletes from Kiev, Valeriy Bondarenko, a Muscovite Valery Efimov and the author of this article. All mini yachts was created on the basis of requirements for models of class F5-S (with an area of 0.5 m2 sail). The best results showed catamarans. In the future, on the basis of their group Kazan modelers have worked a few designs, which already could compete with the traditional single-hulled yachts with moderate wind and have a distinct advantage with strong.
Probably, no other household item, about which the readers of “M-K” wrote to us so much. Indeed, it’s a shame to throw away such a beautiful, bright object just because he has steals bristles. Published in our journal offers to Make an old toothbrush hooks for clothes y towels, tools for polishing metal, pointers for Read more…
Someone in snowfall joy, but not the wipers. Armed with shovels, they morning twilight intrudes on the hard watch. Before the snow raked wooden or plywood shovels now — dural, wide. But to clear the sidewalk could not be soon.

When I opened this, the most usual door of the model apartment I was not in a normal hallway, and… However, in order. Inside the door was as if hammered together from thick oak, the dark time of the timbers, caught blued loops with zip ties. From the right of the entrance two narrow Windows streamed the light of day, Aza patterned glass lurks some kind of “medieval” landscape… In the wall between the Windows a mirror in a frame of beaten copper.
In 1980, the sub-Commission on the rocket modeling of the FAI decided to introduce a new class of raketoplana S8E with a maximum mass up to 300 g engine with a total impulse of 40 n*S. Model of this class, created by Bulgarian athletes participated in the competitions and showed good results. Having the necessary materials, it is easy to make in the flying circle. The engine of rocket with a total impulse of 40 n*works for 10 s. To control the model can be used in compact radio equipment “Craft” or homemade equipment, the mass of which does not exceed 80 g. Usually its the power supply applies a battery capacity of 0.1 Ah and a voltage of 4.8 V.
