There are several classes of ship modeling, in which the apparatuses have very small external differences. So, very similar model classes F1V-15, FSR-3,5, FSR-6,5, F1V-5 and F1-E. “Why build model-twins to participate in different competitions?” — decided the Kazan athlete master of sports G. Kalistratov. And developed a universal body that is equally suitable for models of all five classes. The result is a great model, built on the basis of this hull showed at the competitions excellent results. So, in 1980, G. Kalistratov became the champion of the USSR in the classes F1V-15 FSR-3.5, in the same year, took seventh place at the world Cup, while also installing all-Union speed record, and a year later, speaking in class F1E, won the world championship.

In recent years, the aviation enthusiasts in many countries are showing great interest in flying on makeshift gliders-the gyros and the gyros. Inexpensive, easy to manufacture and easy to pilot, these aircraft can be used not only for sports but also as an excellent way to familiarize wide circles of young people with the element of air. Finally, they can be used for communication. In 1920 – 1940th years, gyros were built in many countries. Now they can be seen only in museums: they could not compete with helicopters. However, for sporting purposes the gyros and especially towed gyroplanes-gliders are used in our days (see figure).
The machine is designed for everyday use and the near and even distant tourist travel not only on asphalt, but off road. The basis, or rather the prototype was an old GAS (UAZ)-69. The body is home-made, welded of steel sheet. The rear part of the crisci – panoramic glass removable. Almost half of the front of cresy made a sliding hatch.
The plane “pilgrim” in the Tver club “Aviator” was conceived in 1978. He was born in the debates and discussions. In the end, it was decided to build it in the scheme of “Demoiselle” in flight technology: soft dual wing. The design relied on overloading the
The ATV is made of that which was in the garage. Generally in the construction tried to use as many parts from domestic cars. Yes, and that turning was smaller. Engines with gearbox (welded differential) – from the car “Oka” VAZ-11113. Quad – double. Seat though homemade, but made on the principle of the factory – the passenger sits slightly above the driver, it has the backrest and footrests.
In the journal “modelist-Konstruktor” No. 11 for 1981, we reported on a new category of raketoplana S8. In the same issue was published the drawings of models of the class S8A. Today we offer to your th account the description of another rocketplane — class S8D. It is interesting the original design of bearing areas of changing geometry. Furthermore, it simultaneously satisfies the requirements of category S4. Similar models in the class S4D Moscow athletes competed at the Championships of the USSR. The proposed design of the rocket plane designed by head of the circle of the Moscow city Palace of pioneers and schoolchildren by V. Minakova.
With a slight rustle of the blades of the propeller model took to the air. Passed one circle, two, three. All this is familiar today in many circles of our country guys raise flying model aircraft with electric motors. However, some features of this device are forced intently follow him. Whether unusual for a rechargeable element wing — flaps, or confidence, a kind of reliability of the flight. After all, we are accustomed to the fact that the power of the motor just enough to keep the model in the air.
Looking through the model magazines for the last couple of years, you’ve probably noticed a sharp change in the appearance cord racing model aircraft. They have disappeared, it would seem, absolutely necessary stabilizer. And it’s not just a tribute to another sport fashion. See what kind of patterns are models of the prize-winners of competitions of different ranks, increasingly they are flying wings. Some of the appearance of these devices, resembling a kind of pancake, not like others talking about a more modern and rapid appearance of the model. But form form and racing microplane primarily sports equipment. And from this point of view, a flying wing has many advantages over apparatus of a conventional circuit. What? First, the “tailless” much easier. Typical “representative of the” new school weighs 150 g, while an old over 220 g (without engine). So, significantly reduces the time during which the model accelerates to maximum speed. Yes, after stopping the motor it is hindered by the faster. And this win precious fractions of seconds! Less weight leads to less tension cord control. The pilot is getting easier: even at high speeds the centrifugal force is not so much to strain the hand.
You never thought about the fact that your car racing has a good gyro, and not one? But they are made and put into place your own hands! Their role is carried out by the engine flywheel and gear wheels. In the not-so-small mass and size, the frequency of their rotation is so large that such is not always seen in the “adult” technique.
Why would a self-similar wheels protector? Go RC micromachines on the asphalt, the dirt it knead not necessary. But let’s see what kind of speeds these cars run, what turns them brought to pass!
