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.PISTON — JET

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.
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.
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.
The industry has already mastered the production of some basic parts from thermoplastics. This is an interesting and promising method for production of large series, however, for individual products it is of little use — complex technological equipment. But similar results can be achieved by using has long been utilized by modelers epoxy resin in combination with glass and carbon fibre.
The smaller the cubic capacity of the engine performance, the more stringent the requirements for its design, manufacture, Assembly. Speed, cord of 1.5 cm3, which we offer, fine-tuned for many years, takes into account the shortcomings of previous designs and new directions in creating “polutorachasovom”.
This model has for many years successfully “replicated” by the modelers. The secret of its popularity are the simplicity of design and good flight qualities. And despite the immutability of the size of the “serial” model, in various instances were established micro-motors a working volume of from 2.5 to 4 cm3 in the compression and glow options. But the most often used are widely known for KMD-2,5 and equipped with a propeller diameter 220×120 mm Length of cord, generally used for runs close to the standard value of -16 meters. For the manufacture of parts of the model mainly applies to non-deficient materials.
To accelerate the construction of highway performance in the circle of Taldy-Kurgan regional station of young technicians was created a set of tools:
At competitions in ship modeling sport of most interest among audience and many athletes call the competition of high-speed radio-controlled models figure chart. The most popular of them can be considered a model of the class F3V — free design. Their creators usually distinguished by deep knowledge of the operation of radio equipment, motors of internal combustion, the skill of “navigation” and of course specific practical skills.
