Since 1983, the Federation of auto modeling sport of the USSR introduced the class E-2. It includes the simplest kordovye model cars with electric motor supplied from the outside! about current source. A new class immediately attracted the attention of young athletes. Simplicity of design, availability of materials and engines, the possibility of competition in every gym, even the school, equal conditions for all invaluable advantages, especially from the standpoint of the development of mass automodelisme. Because machines of this class no matter what the weather outside the Windows, in the village or in the city is a circle of aviamodelirovaniya.
What are the basic requirements for models E-2? They are simple. First, and perhaps most importantly it allowed the use of only standard microelectromotors produced by the Moscow factory of toys or Estonian plants! “Normal” voltage is 3.5 V. second, the model should be similar to a real car (sport, serial) and carefully decorated. A sloppy appearance may lead to the fact that the jury will not allow her to compete. More restrictions that are directly relevant to micromachines, no! But there is a possibility of finding optimal designs and best running of the scheme. The only thing that is mentioned in the rules relative to the model, is the mandatory presence of stopping devices, and requirements for cord strap. The distance from the axis of symmetry of the machine to the holes in the strap in the range of 130-140 mm minimum hole diameter of 3 mm. Strap should carry two contacts ø 2 mm, similar to the core end glow plug. With their help, the motor is connected with the electrical Konami. Speed measurement is carried out with speed on the base 4 of a circle when radius is set to “track” 3.5 m external Power supply must be capable of regulating the voltage on the cords in the range of 0-6 V and change the polarity. A current source is a rectifier on the output to 12 V DC voltage.
