Attract the attention of athletes and spectators time the model is tailless. Most of them presented in the traditional competition “Experiment” in recent years, has a wing to direct the sweep and power system tractor or pusher propeller. However, this scheme has a number of inherent disadvantages. So, with the engine in front of the wing there is a need for additional balancing weight for balancing the tail model, the tail boom has to greatly increase to ensure a sufficient efficiency of the vertical stabilizer. And when using a power plant with pusher propeller there is a significant probability of hitting the hands of the athlete during the spinning propeller when starting Tierney.
This two-cylinder engine, which received the name DD-700/40, designed and built the head of the public design Bureau “Aerocam” George Dorfman. The motor turned very good: reliable, relatively simple, easy enough.
…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 “M-K” was published, the drawings and description of electric spinning-wheel; material found a ready response among our readers. However, some believe that an electric spinning wheel to use is not everywhere and not always convenient, and therefore asked to talk about simple, non -—, “grandmother”. For Example, N. Konovalov from Transbaikalia wrote us; “In the village of Russian Samobranka a necessary thing, and the city will come in handy too. But the thing is that artists who could make this old tool with foot drive, virtually no.” We offer you to become the master, the drawings and description of a spinning wheel is given below.
Simplicity in manufacture and maintenance, reliability, versatility— these are the qualities that I wanted to achieve by producing tillers. Now, after two years of operation at the farm, I can say that the goal is achieved: the machine has become an indispensable helper with a set of attachments walk-behind tractor is used For plowing, cultivating, hilling, harrowing, and in winter — to clear Paths of Snow. In the coupler with a single axle cart with a wooden body and driver’s seat, turns the self-propelled chassis carrying up to 200 kg.
For many Amateur designers is one of the most challenging elements is the frame. On it are mounted the main aggregates, it determines the strength and dimensions of the future car. And to make the most simple and reliable — welded — not always possible. That’s why published in one of issues of “Panoramas “M-K” design of motor-plow assembled on the base frame from the bike, interested many of our readers. About your veloplugs created by podcast magazine, says our reader of the Kharkiv region, V. A. Zayets.
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.
