For a start I suggest the readers-to motorists to conduct a little experiment. Once outside the town, stop by high-speed stretch of highway and watch whizzing past you cars. However, here you need not to watch but rather to listen. A quarter of an hour you will learn to distinguish aurally, the main types of cars: a sound portrait of the major role played by a characteristic noise of the flow over the body. But here comes a car with a roof rack and audio, the picture changes dramatically. The impression is that the car literally pushes through the dense unyielding environment. By the way, the impression is confirmed by experiments in wind tunnels. Purge models and full-size cars with roof racks have shown that increases dramatically the so-called Cx is the drag coefficient. But it depends on the speed and fuel consumption.AND TRUNK, THE AERODYNAMICS!

“Made without balsa? Then bad!” — is unexceptional opinion about aerobatic traditionally there is a perception among most athletes. Especially categorical estimate the model from the point of view of its material beginners — experienced only pilots first, to clarify, do not use fiberglass.Maybe you shouldn’t be so categorical in his judgments
Long gone are the days when the construction of the RC was the prerogative of only experienced, cool modelers. Today, even the newbies that come to join the circle, to the question of what they would like to do, we always answer: “high-Speed RC”.
It is well known that the wind fairing is not a tribute to the motorcycle fashion, and not only protect the rider from the cold and dirt. A well designed shield can increase the speed with two-wheeled machines due to the reduction of aerodynamic drag. But the appearance of the motorcycle fairing attaches to consistency and completeness: the motor vehicle acquires its own entity, releasing the car in several thousand likes.
The first year guys of our circle are doing Svobodnoye. Young athletes usppi to accumulate a lot of experience in the construction of light-winged paritala different classes and their application in the competition. The only time “school” class engines working volume of 1.5 cm3 was DPJ us a kind of a stumbling block. What depot!
Regularly model airplanes-conovici come to the world Championships, to hundreds of athletes to identify the most strong, the most experienced craftsmen. Last year the venue was the Hungarian city of PECs. It was there that he developed air battles in the four most popular classes cord models — aerobatic, speed, racing and fighting. All four classes and in team and individual competition — confidently leading modelers of the USSR team. In the end, the gold medal of the FAI and the title of world Champions respectively, got A. Kolesnikov (Frunze), Kalmykov (Moscow), the crew Barkov — Suraev (Kharkov) and N. Necheukhin (Sverdlovsk).
In the “M-K” (No. 11, 1990) was described by the model of the strongest tracks. However, the production of such equipment is not available to everyone and is quite expensive. And what do the athletes do not have much experience, and beginners in the club? For them it is proposed to develop a model of THE class-2 modern design, but runs out of available materials and without using complicated technologies.
Growing every year in our country, the number of motorists. For many of them the car is not only a means of transport, recreation, but also technical creativity. It would seem, than still it is possible to add, improve released in a modern plant the design of a brand new car! But for the curious enthusiast with skillful hands here even boundless field of activity. To them and turned a new section of our magazine “Car “M-K”.
Without the engine the model doesn’t fly. But to rely on the ice today is not necessary: the mass of the motors is just terrible. You can, of course, many years ago, to do “resinator” but now this model guys inspire difficult. Meanwhile, there is the engine, capable of becoming the progenitor of a range of models for beginners air (though why not a car or ship) modelers. This is a pneumatic engine, working on liquefied carbon dioxide WITH2. It has a quite satisfactory capacity to fill it is easy, fuel is not harmful to children. Today in the Moscow city station of young technicians developed several types of models for competition of Junior high school students and first control line racing, Svobodnaya the replica model and timer model airplane. Today we introduce readers to “M-K” with “timerkey”, which showed very good results in numerous experimental runs.
In the “M-K” No. 4, 1984, an article was published about the use of modular monoblock with rubber motor sports boat. Over time the scheme not only fully justified, but has evolved into an electric version of the modular drive. It should be noted that with the same size seats remains a possibility at any time to return to rezinomotornaya. Development has passed severe tests, not only in training: with electric monoblock model was “RAID boat”, became the winner of the championship of Moscow among students.
