The prototype model has served as a snowmobile amphibian created in 60-ies a group of young professionals under the leadership of the Soviet aircraft designer A. N. Tupolev. This car attracts the severity of the contours (see “M-K” No. 11 of 1978), do not break any complex suspension system of the ski or tubular enclosure of the propeller. And this is a significant advantage Because each protruding element design increases the aerodynamic resistance. It is better to have a bulky, but streamlined body than compressed to the limit, but with the “stork” legs of the undercarriage. In addition, the housing of such a model creates the effect of aerodynamic unloading, manifested even at low speed. Amphibians have relatively small diameter propeller.

Many can make a shift to summer camp? Because it ends so quickly! And no matter how much enthusiasm in the students-smart, funny, summer time beckons them to postpone for a time the tools to escape into the forest to the river or to play football. But there are models that even beginners have time to build just a few classes. And not only build, but also want to experiment with them and compete. These include models of a wheeled yacht. The smallest automodellista it is possible to offer a simple boat. Composing elements in different ways, it is easy to create the most unusual “asphalt sailing”.
Devices leading only pilots, in General, very similar in scheme and design are very different in administration. The reason is simple: everyone builds a microplane “under his hand”, presenting to him the more requirements, the higher the class of the constructor. But even the slightest innovations often lead to a significant change in the flight properties of the model. Therefore, when designing pilotazhki impossible to do without hints of a rich and practical flight experience, solid theoretical knowledge.
None of the types of modeling to the apparatus is not presented at the same time so many conflicting claims as to RC jumper gliders. Imagine that you need to design a machine that combines the properties of high-speed models, gliders-paritala and apparatus created specifically for ustanovlena of records range.
RC model aerolaser (Fig. 1) easy to manufacture, and it does not require scarce materials. Do this even for a Modeler with a little experience, and so the airboat could become a learning model figure chart. This boat great sailing qualities: it handles well, quickly leaves on glissirovanie, stable moves for all evolutions, sufficiently stable. Even with a strong gusty wind model but out of control.
Avtomodelistov riders as it is not accepted to give the models names. Perhaps that is why the first thing we asked the author of this has no similar model, the origin of its name — “Vyatka”. Instead of a response, the designer withdrew from subtle glass-plastic fairing. It was very similar in layout to those produced many years of domestic scooter VP-150 Vyatka: console attached to the engine block the rear wheels, the engine — side of the longitudinal axis.
Most often the chassis of modern highway car made of metal. In the case are tinplate, thin sheet duralumin and brass, steel wire. Requirements and the chassis is presented are many, and each new version is to some extent intended to satisfy them. Designs, at the same time perfect in all respects, have not yet been.
The competition for these ship models at first glance is simple, if not primitive. What could be simpler: he included the engine, took aim and wait for the “jug” slip in a shot finish. Straightness is all that is required of the movement model class EX.
This unusual model was built by members of syt Berezniki, Perm region. Copy flies perfectly, performs such demonstrations as “flying under the 45° angle” and “pipeline.” Remote speed adjustment of electric motors allows the model to freely come to the “stopover” and after run on the ground again soar into the air so that sometimes it seems — before you the real Il-4. With the design of the copy you are acquainted the head of the aeromodelling circle N. YAKIMOV.
Not for the first ten years there is a class of experimental aircraft. It would seem that this time is sufficient to clearly determine the best scheme inflected wing”, the most favorable profiles and types of balancing. But every new competitions at the Tushino airfield, gathering creative enthusiasts from all over the country, convinced that the search is not yet complete. And it is not surprising to achieve stable flight model “flying wing” in contrast to the classical devices are very difficult. Why so few “highs” in the tables of experimental results, although at first glance the benefits seem obvious tailless.
