Continuous improvement of engines and circuits cord boat allows them to develop increasingly high speed. Along with the design changes and the appearance of the apparatus Particularly dramatic changes have undergone recent high-speed model with aerodigestive. But in the class A1 scheme over many years remains, essentially, unchanged. Most athletes prefer to speak with a reliable traditional pattern: vertical location of the engine at the main building, equipped with two additional floats. The most careful attention is paid to Moto installations.

…Lined up at the edge of the pond, the boys tensely listened to the pre-launch countdown seconds. In the right hand each refined model of aeropittura, left index finger slightly trembling, touching ready to spin the propeller. Finally, the command: “Start!” Engines do not fail young athletes; almost all microSD rush to the opposite shore. And what is happening in the ranks of the fans!
In the “M-K” No. 4 in 1983 was about a cord of car-class copies of “rally”, developed under the direction of E. Voronin. The design proved so simple and reliable that are built on published drawings of a micro-Skoda is not the first time, always steadily showing high results. I especially want to mention the original and again is extremely simple in scheme and execution of the automatic control (hold set) speed.
We are all accustomed to the fact that it is a machine fit only to acquire initial skills of piloting. In most cases, training is built almost without any requirements for in-flight properties. The main thing — to provide the maximum ease of manufacture. Eventually, when the athlete will be accepted for the design of the following models with which it will compete, will be subject to calculations and aerodynamics, and strength of materials, and materials science. But at first — what to suffer, whether… And see the light polulotosa “snags”.
The proposed model is performed according to the scheme “duck”. The stabilizer is located in front of the wing, contributes to the sustainability planning mode. A deviation to vertical position after deployment, a simple “timer” (wick device ignites the expelling charge motor) ensures a safe landing apparatus.
We can safely say: engine MK-17 “Junior” is familiar to all modelers. One of the most popular among beginners and are produced in large series, it encourages the modeling of thousands of boys. Under the motor created a lot of industrial kits, semi-finished products. With models equipped with “Juniors” are the first sports categories air-, ship-, avtomodelisty-students and young builders of the different copies.
Continuously growing speed racing car, top athletes, designers are finding new technical solutions that increase the speed of avtopoligon, new methods of forcing-engines, better ways of suspension. And as a natural result — new records. So, last year, the master of sports of the USSR, Leningrad A. Medvedev at the all-Union competition “Match the fittest” broke the record of the Soviet Union — his polutorametrovy was racing the distance at a speed of 223,880 km/h!
Only four minutes, the athletes rakatomalala to prepare for the start. How much do you need to keep up with the time flying at the competition as if one moment: to install the model on the guide pin. To connect Elektrostal, to determine the atmospheric conditions at this point and calculate the direction of flight, accurately to execute the command “start!”.
Today, we first introduce you to the most massive representatives of the ship-class F1-V. This high-speed RC ships with engines working volume of 10 to 15 cm3. One of the most successful developments in this subclass is the model A. Baidebekova.
The design sports a model rocket with a streamer class Б6А traditional. Athletes rocketmodeler repeatedly noted that models in this class closer to a kind of optimum. Now much depends on the quality of manufacture and Assembly of their components. The proposed model is performed based on these requirements, can show good results in competitions.
