A lot of history in the fate of the car racing! Even now, when they are built almost the same pattern, in conversations the athletes to hear the terms “boat”, “drop”, “arrow”, meaning certain areas in the layout. Remember that was a “drop”. The name itself speaks about the shape of the hull. Aerodynamics have always maintained that the teardrop body has the lowest drag, to overcome which spent a large part of engine power. The advantage of “drop” and that it is well located for the centre of gravity of the car: it is very close to the drive wheels. This means that irregularities of the track model of this type will respond much less.“DROP” ON TRACK

The reliability of the system control cord model aircraft is one of the most important factors of success in the competition. Equally important is m, as suspended from elevators and flaps. No backlash, ease of movement, vitality — these are the main requirements these nodes.
In the autumn of last year in Tashkent was held the second personal championship of the USSR on flying sport, which was attended by 53 athletes from almost all the Union republics of our country. According to the established tradition, the championship was played in three model grades — SE, S4D and Ѕ6А. The editorial Board appealed to the chief judge of competitions the master of sports V. S. ROZHKOV to comment on the results of the competition, to talk about the changes that are made to already existing design of rocket modeling championship winners — leading athletes of our country.
Last summer I happened to be in one of the suburban pioneer camps. Freshly painted hull, the green of the grass and… a person! A bewildered look around. From somewhere far away I heard gambling and shouts, noise. The camp Olympics? Moving in that direction, I soon came to the paved area where usually held solemn ceremonies.
In 1978, at the international motor show in Paris was presented the new sports car BMW M1. He is currently considered the fastest car of the company, and this was achieved not only due to the design features, but also because a fundamentally new approach to design. Racing cars are usually created on the basis of serial models, but the firm BMW chose a different path. BMW M1 from the beginning was created to participate in competitions, and requirements specific requirements take into account not only when designing the engine, but the bodywork along with chassis, It is possible to achieve the harmonious unity of all units of the car with a powerful engine and is easy to assemble them with a “good” motor.
What are the only propellers is not built by modelers. Due attention was paid to the three blade. Why not try to install them on a modern cord “acrobat”? If Yes, will any benefit from the extra blades? Elaborate design, drew and made templates. Finally cleaned the sawdust out of the room evaporated the smell of varnish. The case for breakdown in air.
The model is ready, applied the last layer of putty. It is time to begin painting. Soon the model will become strict and graceful look, will emerge more noticeable the line of lines, curves, a glossy surface will fall light patches. You can understand the impatience of the young designer when there is so little to the first test of the new device. And now look what happened… Ran, although not very clearly, traces of brushwork, striking streaks of paint and blotched, uneven border colors.
Maybe someone will seem ridiculous the claim that wheel the machine can fly over the fence, but not young technicians from the laboratory of experimental modeling and design Cute Novosibirsk Akademgorodok. On the contrary, they talk seriously about the ability of the wheels to overcome ledges, ditches, steep slopes… And in support of their arguments build working models of all-terrain vehicles. One of them is remotely controlled amphibious Atlant — created by young designers Cut Lipenkov Andrey and Dima Yakovlev.
Is a beginner model airplanes at least once to see the competition of the dogfight, as he immediately declares: “I Want to build bouzouki!” And it can be understood: indeed, the air battle — an exciting spectacle, besides themselves “fighters” is so simple that just a few days the athlete, who undertook a new car, already feeling it in the air. And then you can dispense with the use of scarce balsa. And unlike other classes in a dogfight is often possible to achieve good results even with accelerated serial domestic engine.
Today I want to introduce You to the model class B1, having almost the same set of wings. This force diagram consoles with a transverse set of pine slats is fully justified, since for such models, the requirements of stiffness, processability and low weight is no less important than for a glider.
