RC model-polyopia motor. Motors together with batteries increasingly gaining ground in the modeling. Today, the growing power motors and improved battery options allow you to create a comprehensive, well-flying model aircraft, including radio controlled.
The attention of many modelers are attracted to the photos (“M-K”, No. 10, 1979) on the international competition teams of the socialist countries on aviamodelling sports. The editors have received many letters with the request to give more details about the model of the winner of these competitions the master of sports of international class Anatoly Kolesnikov from Frunze. To fulfill these wishes. L. Kolesnikov talks about his Cordoba flight.
Every year fewer and fewer aircraft with piston engines. Lightweight, economical running on cheaper than gasoline, fuels, jet engines replacing piston even from agricultural aviation. But in any aeromodelling competition still reigns “piston era”. On kartodromo you will see the masterfully made copies of “Ilya Muromets”, “Nieuport”, I-15, Yak-3… do Not attempt to only search for a model jet aircraft — the era of rapid modern machines in modeling has not yet arrived. The reason is the lack of jet motors or at least their imitators: piston motors with impellers. Unfortunately, numerous attempts by modelers to create quasirational the engine was not successful — usually these devices have extremely low efficiency and did not develop the thrust required for steady flight of the model.
With all its advantages of an inflatable boat of any design has the same General disadvantages: Shorty wislica, turtle speed and bad handling. From all of them at once we managed to get rid of, adapting your boat “Dive-4” under sail: with him she became and the faster and more manageable. And actually upgrading was quite simple and compact, that is blended with the amenities characteristic of inflatable boats.
Build model rockets. The first manned flight into space, our compatriot Yuri Gagarin in 1961 was the beginning of a new the directions of technical creativity — rocket-and-space modeling. And from the first steps of this interesting kind of design magazine “modelist-Konstruktor” became its active promoter and popularizer. And loyal to him until now.
In the soul of every boy living Navigator, so any rain brook — is a river, and a large puddle is a sea calling out to let the boats from the simplest of chips or a sheet of paper, to specially planed, and the more such combined, as proposed by the German magazine “Technium” self-propelled model of a boat. Yes, no ordinary boat, but an old, two-pipe, with paddle wheels at the sides. What child would not want to build like this, especially because the design is quite affordable for independent playback.
Wheeled Buer, beach sailing, sand yacht, metromobile… All these terms refer to the same Tina of vehicles using the movement force of the wind. Designs of such “petroholod” — a great many, from year to year are added up — three wheels and four, with Latin sail and with the Bermuda arms, hard planes, reminiscent of an aircraft wing, and even with a horizontally positioned fan-like impeller anemometer.
A simple device developed by members of the self-similar circle of Ufa city Palace of children’s creativity, shoal be useful to many tracks. It makes it very easy to create a miniature race track for sea trials models. We have seen this, having tried it, in fact: “digging,” grooves on a track is accelerated many times over.
No matter how much we have seen this picture every time it will amaze and fascinate with their uniqueness: easy flick of a switch — and just as silently as it stood, the car started and ran, picking up speed. The heart of this design — the electric motor. To it again drawn the attention of automakers and even in connection with energy problems. Do not stand aside from these searches, and Amateur designers, some of their works have been highlighted on the pages of our magazine. Today we introduce the electric car of formula D — baby, built by our reader A. Logvina from the city for his daughter called “Alyonushka”.
Speed kordovye models are very popular among modelers of the USSR. According to the classification of models of the ships they are United in group a-and are divided into four classes: A-1 — speed cord model free design with internal combustion engines working volume of 2.5 cm3, with the propeller; class A-2 — speed cord model free design of the internal combustion engine up to a volume of 5.0 cm3, with the propeller; And-3 — speed control line model free design of the internal combustion engine up to a volume of 10.0 cm3, with the propeller; In-1 — speed cord model free design with internal combustion engines up to 1.5 cm3, with a propeller.
