Conceiving a new microplane, any Modeler primarily decides which engine to put on it. One of the motors power is not enough, others too large, others strongly vibrate during operation. Many disadvantages of single-cylinder engine delivered a two-cylinder of the same displacement. They can be built on a variety of schemes: boxer, Y-shaped, inline. In some cases, if the Modeler is not very important weight, two normal “odnotrahniki” mounted on a common metal frame, connecting the shafts through the gear transmission. This allows to raise efficiency of the propeller by increasing its diameter at low speed.OF THE TWO “COMETS”

On the Fifth competition of the European championship miniature rocketmodel class S1B master of sports of the USSR Yury Soldatov brought its designer, the title of champion of Europe 1981. She rose to a height of 1046 metres! Design model developed by a team under the leadership of V. Minakova. Thorough testing of the technology, the reasonableness of the scheme made the aircraft a kind of benchmark: with missiles of this type were made by all members of the Soviet team that won first place in the championship.
It would seem, what new it is possible to invent models of air combat! Undoubtedly, these microstrobili today meet all the requirements of transient encounters over the track. No wonder even top athletes can be heard that the best equipment they are not necessary, it’s just a systematic preparation for the training athlete.
As you know, aeromodelling motor “rainbow-7)” is a typical “Kalinka”. But a few additional parts easily turn it into a compression engine with a displacement of 7.0 cm3.
Said to be good the model airplane itself teaches us to govern ourselves. Especially valuable is her property for beginners korovikov. However, apart from flight, training models required: maximum ease of fabrication and strength. We offer our readers two successful design for the initial “school” for learning the basics of flight complex. These models-coaches can help young athletes become faster first-class masters.
Category sport model rockets with a soft wing (S10) is divided into four classes. The most common is the class Ѕ10А. Requirements for models are as follows: maximum total impulse MRD — 2,5 researcher, the starting mass of not less than 18 but not more than 60 g. the Maximum flight time in a round is 180 sec (3 min).
The one who animaetsya room with model airplanes knows what a difficult job the installation of the stretch marks. But they stiffen the easiest transparent planes, and even a small error in the tension lead to distortion of the shape of the wings. The work is delicate, painstaking and long. And if you say that you pereustanovit model (you need to remove the “wood” braces) to bring it into working condition for 2-3 minutes, and even in terms of competition, it will seem unreal to you. However, after reviewing the proposed method, you will see that it is quite possible.
Any of us can certainly, without hesitation, to list a lot of famous planes, cars and ships, inscribed your page in history of development of military and civilian equipment. However, it turns out, the model a scheme could play a significant role. Let not the history of all the equipment, and only one type of technical sport.
The kid from the first start push-rod started the engine, and early test-in. The engine revs, causing the car faster and faster to run on the track. Here are the included machine-cut timing a run of eight laps of the race, which is determined by the speed of the model. One lap to another… But it is! The impression is that someone hung on the rear wheels of the machine and slows down her run. Smooth, easy sound debugged in training “engine” was replaced by strained, jagged roar. Of course, the speed shown “shell” is too small.
In his hands standing on the bridge of a schoolboy elegant model powerboats. The boy winked one eye, as if before the shot. Finally, the wind has abated a little — it is possible to produce a model. Raising astern low backwash water, the boat went to the goal. After fifty meters posed a number of buoys, medium form the gate width of two meters. It is best to get it in them — a rating in the highest. With a frozen heart, waiting for the young athlete how to behave microcode. There is a hit! Even the rising wind and waves did not prevent him to enter into the Central gate.
