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 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!
Its high performance is a boat more suited to voyages on inland waters and small weight of the hull allows to deliver it on the upper trunk or the trailer car almost any “blind corner”. Chibis can be recommended to fishermen and campers for offline (up to two weeks) trips of two people or of hikes of the day the three of us. Will like this boat and the villagers standing along the banks of rivers and reservoirs, as an everyday vehicle, the more that the opportunities for installation of outboard motor, sails or oars makes it universal.
As evidenced by the mail, under the heading “Small mechanization” is very popular among people whose work directly or indirectly related to agricultural production. Of particular interest to readers are self-propelled mini-tractors — tillers. After “M-K” has published a description and drawings of “Vyatich” (see No. 7, 1981), built by engineer S. A. Ilyicheva, Amateurs agricultural design write and call the editor with a request to continue the conversation on this topic.
This mini tractor was built in a family of Amateur design Bureau of Paul: under the guidance of the head of the family of Valery Vasilyevich machine was assembled by his sons Sergei and Andrei. All three are longtime readers of the magazine “modelist-Konstruktor”. Small-sized tractors, called by its creators the acronym SAP (S. A. Paul), is designed as a universal – tilling and transport agricultural unit. He can plow, cultivate, harrow, and to tow a cart with goods or a small tank with a capacity of about 100 litres for watering the infield.
Develop some automaticity in managing the cord of the model during takeoff and horizontal flight, you can begin to build more complex apparatus. It will help you to learn how to perform all the basics of flight complex: forward and backward loops, turn and slide flight “on the back”. Unfortunately, your first robust model of these figures can not do too heavy reinforced design. Therefore, flight training is based on a different principle: the minimum weight, which gives good flight characteristics at maximum ease, which will allow you to repair the microplane for a few hours and re-enter the track or in the field.
