ROWING – SAILING!
EASY TO WASH, AND SORT
FLIGHT “ON THE BACK”
HARNESSED THE WINCH..
Winch, in combination with a plow, not news. Especially for owners of small plots of land on which these pretty simple and reliable konstruktsii a great way has already established itself. Unlike the mini-tractor winch not compacts the soil. And not stalled, as the tillers. But almost all traction motor power goes into useful work — plowing the earth towed plow. The winch is held securely in place by anchor legs which, with a kind of bayonet shovels, lengo deepened into the ground. Plowing are together, making a furrow for furrow. With a partner, the duties of which include the return of the plow n the beginning of the furrow may be 10-year-old child. High kachestvo spalni is guaranteed even at extremely inconvenient uchastkah (slopes with a profile like a “washboard”) and heavy soils.
“VIRTULA” FOR ALL
AS I DO MOTORCYCLES
BOUZOUKI “JUNIOR”
Developed and comprehensively tested in our circle, a new model of a subclass of 1.5 cm3 was very successful. For it is characteristic of a good combination of flight stability and high controllability, and wide adjustment of these parameters. The model has become simply indispensable for us, as it successfully functions as a flying trainer beginner certovica, well suited for training of more experienced and fully meets the requirements of boys-sportsmen even in senior competitions. Do note that bouzouki has very good strength characteristics, and in case of serious accidents, the subsequent repair is not a problem. In addition, when the semi-manufacture of such devices in terms of mug is that new development quite technical.
MOTOR WITH… A TABLET
LAND THE BOATS START
In the February issue of “Modeller-designer” we met article on the development of a new class of car — unmanaged vetrogonov. Don’t know how reacted to the most interesting suggestion of the authors of that article and the magazine automodeling Federation of sports of Russia, but in our circle it was accepted “on hurrah” — so interesting, affordable and promising was this topic. Work on a new type of machines we started with, that surely will be useful to all, tion interested in constructing vetrogonov — with the development of minimized similarity of the internal rules of the competition and technical constraints applicable to unusual models. On the last point we were limited to only the maximum area of the driving model sailing arms (no more than 25 dm2) and the total dimensions of the machine (prepared by the start condition, it must fit into a cube with sides not more than 1000 mm). Under these constraints, Verkade should be potentially very fast and quite “personable” for forms that will go only to the benefit of the attractiveness and popularity of the competition in the new class. It should be noted that the rough calculations of the maximum potential speed of movement convinced us in the fact that would be very useful, additional development is reduced “oneorzero” type vetrogonov. Here are our suggestions tanovi: sail area limit of 10-15 dm2, and dimensions described Nuba 500-600 mm.
