The problem of choice of the first model arises not only to beginners but to the heads of circles: what computers have to offer first came to class? After all, you need to choose one that is not so difficult to build and which will not test the patience of the young shipbuilder of his “mnogozadachnosti”. But the model should have good performance, not to stay in last place in the competition, and appearance as close as possible to this ship. All the required qualities have proposed a model-“Pramod” class EX-500 (polyopia length up to 500 mm). Its able to build even a novice athlete, working independently, without the help of the instructor.

It’s a letter to the editor. In it two leaves of sketches on the reverse side of which a short description and a few photos of the model. No return address, no signature of the author. What is it? The mystery still remains unresolved. But one thing is clear — sent material about Cordovan Aero glider will be important for athletes, both young and experienced. Proof the experts say to any of the claims from an engineering point of view is not the “fault” — all the calculations are justified! The editors decided to publish the anonymous letter. Because navarana if not the overall scheme, at least part of the individual decisions will the creators of sports technine tomorrow. We can only thank the stranger who made such an unusual gift to readers-modelers. So, we give this letter.
Good modelers! Almost all of the many sports classes they have and the same subclass designed for students. Equipment from the “juniors” easier, more accessible, and to treat her in the competition much easier than with the “older” supermodels of today.
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.
“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”.
