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
There just are not invented contraptions to the front door had closed by itself. This special spring hinges, and cargo the device with counterweights and a pulley system, and various spring or rubber band. There are commercially available, but, unfortunately, they are not without drawbacks: some are too complicated and quite expensive, others are inconvenient to use or unreliable, easily damaged. Therefore, home designers continue on their own to solve these problems, as evidenced by the proposed content selection submitted by readers. In the winter the doors of the entrances of our homes are often left open. This leads to overconsumption of energy required for heating staircases. To save precious heat needed simple automation.
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”.
I work in the locomotive depot of the station Yerofey Pavlovich, produce visual AIDS for teaching assistants machinists of electric locomotives. During the work on the stand pneumatic circuits I have not found a suitable tool for sampling grooves complex profile and decided to make a cutting tool that brings together in its construction, some carpentry. Thus was born the plane-“harvester”.
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).
We continue to acquaint our readers — owners and garden plots — with non-traditional designs of garden furniture, and published in the Polish journal “Prob myself.”
