THE TRACK ON THE TABLE…

ASSEMBLY ON THE TABLE...Performance with external power supply grade E-2 is very popular with beginners — they are not too complicated for their production does not require scarce batteries, electric motors and materials. Odkako for debugging such models it is desirable to have at hand a track : after all, every improvement micromachine aimed at the growth of its speed, should promptly be evaluated by the designer in order to proceed to the next stage of modernization.

THE WHEELS UNDER CONTROL

WHEELS UNDER CONTROLCamber angles and toe of the car very accurately can be adjusted, without resorting to service stations. We just need to have some plumbing skills and to have the simplest tool to their own to make for this adjustment tool kit, which is easy and convenient performance. Consider, for example, the variant with the car VAZ-21063. The distance between the centres of the footprint of the tire on the ground — 1365 mm. If through these points to carry forward in the course of movement of the vehicle two parallel lines, then they could become benchmarks for subsequent adjustments. However, it is impossible to carry: the protruding part of the side surfaces of the car will be a hindrance. Hence the need for these parallel lines to hold at some distance from the vehicle. To make that possible with the devices, which can be called a protractor.

“NIKE KEYGEN” IN MINIATURE

With the introduction of new technical requirements to models-copies category S5 most preferred as a prototype steel two-stage rocket with large differences in diameters of the housings of the steps. This requirement well enough to answer the research rocket developed in the US on the basis of the accelerator anti-aircraft missiles “Nike” (“Nike-Tomogavk”, “Nike-Keygen”, “Nike-Apache” and others).

SLEIGH KMD-2,5

SLEIGH KMD-2,5A number of recent publications in “M-K” on the cord design racing cars and snowmobiles helped us in creating equipment and more heavy class — under the engine working volume of 2.5 cm3. Despite the fact that the published information has mostly referred to “trucks”, most of nodal solutions have been shown to be beneficial in the classroom as-2 and AM-2. Sharp weight reduction and a simultaneous simplification of the circuit and process of manufacture, the almost total absence of metal and processed by machines details helps aeromarine with “paper” beam and a kind of motor mount on three points and remain leaders in technology, accessibility of buildings and possibilities of achievement of high sports results.

BOAT-PRAMOD

BOAT-PRAMODThe 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.

UNUSUAL GIFT

UNUSUAL GIFTIt’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.

AND TRUNK, THE AERODYNAMICS!

AND THE TRUNK - AERODYNAMICS!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.
