Rapidly running time. In everyday Affairs and concerns we often don’t notice this. Fade and erased in the memory a vivid and memorable dates of the event. But some of them become part of history.
The proposed model torpedo boat was built by students in the 5-6-grade in ship modeling circle of the Moscow city club of young sailors, rivermen and explorers. In both variants rezinomotornaya and two microelectrophoresis — miniature torpedo boat had good speed and stability on the course. The model is simple in manufacture, does not require scarce materials. Young modelers, speaking at the Moscow urban competitions, repeatedly won prizes.
The desire to build a model of a biplane under the existing engine MDS-6,5 KU initially led to the search for analogues. View magazines and catalogs helped to decide what I would like to see a future model. Original design prototype was a biplane DUO 40 of the company Graupner. The outline of this plane was simple and cute. Now it remained only to consider the design of the airplane.
Racing airboat engine “Raluka-7”. The journal “modelist-Konstruktor” has repeatedly told on the pages of the increasingly popular class of radio controlled racing boat with aerodiesel. Is there any need to remind them of the case differ from those created for similar models with the propeller, except that greater width, however, the design of the power unit with the propeller not in the example easier. So, for aerolister not required technologically sophisticated gear reducer, it does not need water-cooling system motor and transmission drive propeller. All this greatly facilitates the work over the model and, consequently, makes it available for production, even for novice athletes.
If you want to argue with the wind, taste the romance of the sea, to learn to manage sails, get to work. We recommend you to modern RC model yachts. It is possible to participate in competitions of any rank. It was designed and built by the instructor of the Sukhumi marine club, master of sports of the USSR, repeated champion of the country Anatoly Deineko.
Racing airboat motor. In the journal “modelist-Konstruktor” is not just talked about RC racing boat with aerodiesel. In contrast to the models with the propeller for gliders with a propeller does not require complicated gear reducer and transmission: because the propeller is mounted directly on the motor shaft. And the engine for the model”train” to get much simpler: in any auto shop, you can buy a suitable 12-volt electric motor, for example, the one that rotates the windshield washer pump or used to Windows. It facilitates the work of the Modeler and allows without difficulty to produce an airboat even the novice athlete.
The learning model is simple. So fly it close and low. Good sports model can produce only an experienced hand. It seems self-evident, isn’t it? But the glider, which refutes many preconceived ideas about the possibilities of training “sketchy”. He developed PA Volgograd station of young technicians in the circle of the master of sports of the USSR Vladimir Bogdanov.
It is made by a group of engineering students laboratory in the Sverdlovsk House of pioneers named after Yuri Gagarin. Appearance of the crane shown in figure 1. On the frame beam crane includes a traveling mechanism hoist (Fig. 2). Rope (cotton fabric) covers two rollers. The drive roller while rotating according to the movement of the hoist carriage, which moves freely through the corners like on rails.
Engine MD-5 Kometa is produced in large series for many years and is established on the models of different types. To simplify manufacturing and reduce the cost of manufacturing allows derogation from increased individual adjustment of the prototype. This leads to the fact that the production engines develop power below possibilities inherent in their design. Only individual samples with the perfect mix of details showing good results.
Sometimes the competition for RC model, not obeying commands, is out of sight. Flies knows where the result of months of labor and expensive equipment. A simple automatic device developed gorsyut Alma-ATA will provide a forced fit of the model. It will stop the engine after some time after the failure of the receiver.
