In the previous issue of “Modeller-designer” followers of aeromodelling was able to gather information about competition rules and guidelines in the new are gaining wider appreciation, direction of technical work — the electrics. I hope that no less favor in entering new theme will bring and a brief description of a few specific successful models that can serve as a kind of “reference point” in the design of this promising technique will become a basis of creation of similar machines. Moreover, the presented model of precisely those classes that are cultivated at present in our country.
Today the state of technical creativity of pupils, I think we all know — it is deplorable. And even a talented teacher to inspire children is becoming increasingly difficult. One of the reasons the sharp deterioration of the material base of non-school institutions that lead to exclusion from group work sites that require long time to manufacture. It is possible to offer teachers some technical circles (primarily — aircraft modeling) to include in the plan of work of the first year of lessons build exotic aerodynamic projectile like a boomerang. Experience shows that it is quite affordable for newbies. Requires wood and simple tools: a plane, a knife, a rasp and sandpaper. Production time is two or three classes.
Interior of modern apartment became fashionable to decorate various architectural forms. These include decorative arch, installed in the openings of corridors. The construction of the arch (Fig. 2) consists of two shaped plates, made of chipboard with thickness of 12…16 mm, sewn stripes hardboard (fiberboard) 5-mm thickness. The arch is fixed in the opening of the wall by means of screws and wooden bosses mounted on the support-base that is attached at the top of the opening. Making the arch begins with the selection of the shape and size of the circuit (in the figure, are the most common form). The contour of the arch is drawn on a piece of cardboard in full size. The layout is only one half to use it as a template for a complete circuit (see figure).
The new rules of competition in the class of models of “air combat” prohibit the use of glow engines without mufflers. Offers its readers the most successful I have developed silencers for the engine CSTOM is 2.5. It consists of a clamp, camera jamming, staples, lid and M3 screws with spring washers.
The Rover was designed and custom-made joint stock company “Sa-ratowanie”: here is a badly needed vehicle for the delivery of operational outreach to places of accidents on power lines. These lines are, as usual, draw where on the roads to speak of. In good weather only army GAZ-66 is still able to build there track. In the offseason, almost as in the song: only helicopter can fly. Mari Rover turned out to be what we need. For four years he has served the energy sector and still on the go. This was confirmed by A. P. Smolkin, head of the fuel and transport service of JSC “Saratovenergo”. Not once, not twice “Wolverine” rescued repairmen. And not just for work but also for hunting and fishing. On the question of what the design drawbacks revealed during exploitation, Alexander only then said: “have more powerful Engine… at least from “zaporozhtsa”.
