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.

Kind the debut of this model yachts was held in the summer of 1981 at the Moscow city competition modelers. Attention athletes was attracted by the unusual hull shape: broad grancey nose, frames Charpy and a large ratio of width to draught. All this has not previously been used in sailing vessels of this class. The experiment was successful: the model showed excellent driving performance both on passing and on sharp courses.
Many RC modelers dream about. Those who decided to engage in this complicated class of models, usually start with gliders. After all, not everyone is lucky enough to find an experienced teacher who would help to develop not a flying machine, gave the opportunity for several days of joint exercises in the field to acquire the basic skills of piloting superkabuto. And the plane with working rudder and altitude to fly slower and more stable pilot error cause only the loss of a few tens of meters height. Finally, the gliders perfectly fulfilled such an important skill, as the automatic steering rotation regardless of where flies model: for the pilot or away from it.
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.
