It would seem, are incompatible. However, wound in a spiral wire can be very useful in the power system. Soft hose connecting the jet engine to the tank, sometimes become a reason for stopping the motor in flight. The root of all evil, it turns out, in that the fuel tube, the bending under the action of centrifugal forces acting on the cord model. You can, of course, apply and a rigid tube, but it is inconvenient because of the difficulties of installation. And so very quickly she “gets used” to inserted into her nipple, starting to pass the fuel through the connection.

Often you can see guys, sorry standing at the wreckage of his first cord model aircraft. Many fail the rocking of the control — or done poorly, or the material is picked up correctly. And so I want to see in flight almost a real plane that you yourself invented and built!
Experienced modelers-conovici much focus on connecting cords and the rocking the control cables. Especially careful they draw their conclusion from the wing — this often depends on the successful flight model as in training and competitions. Accidental kinking of the cable pull — and stuck in the system control leads to the fact that the miniature aircraft crashes.
The model we offer you to make, made by rare scheme — two bearing rotor during rotation intersect. To build it is not very difficult — especially as the engine are well-known modelers rubber tubing. Energy stored in them when you twist, enough to fly a small model of this type. The diameter of the rotor is 600 mm, and each of them has its own shaft, both rotating in opposite directions, which provides a synchronizing mechanism. Four gears cut from metal gears with a suitable external diameter, which you can pick up from parts of an old alarm clock or a broken clockwork toy. After processing, the thickness of each gear should be about 2 mm, the diameter of inner hole is 2 mm.
Of all classes and types of rocket parachute patterns category S3 the most “ancient”. At the dawn of the emergence and development of rocket modeling one of the criteria of the competition was the duration of the flight. At that time it was a simple and straightforward comparative characteristics of flying model rockets. By the way, today the flight is the determining factor the benefits and performance of model rockets with a parachute. And watch the in-flight model with a large beautiful dome — fun.
models of gliders classes A1 and A2 must satisfy three requirements — stiffness, strength and low weight. The best results are obtained by the use of tapered thin-walled fiberglass or balsa tubes. But the technology of manufacturing these beams is difficult. Our proposed design is much simpler, the material for it is available to everyone. Despite its simplicity, such a beam is well proven in operation.
For years, the rubber motor due to its ease of use and low cost were the main engine modelers. But now, with the abundance of micro-motors boat and car with rubber motor find its ardent supporters, as evidenced, in particular, and editorial mail. Among your questions, dear readers, the most frequent two. So T zavgorodnego from Volgograd, E. Shcherbina from Semipalatinsk, A. Zhdanov of Moscow and other interested in how to calculate the number of turns of the rubber motor to maximize its energy, and what is its maximum energy efficiency.
It is hard to imagine the competition without rocketmodeler launches RC models. It is, along with the competitions models-copies, quite an interesting spectacle, including from a sporting point of view. Of course, impressive for the beauty of the start of the model rocket—glider with a rocket motor and control its flight using radio signals.
The model, which will be discussed, applies to the class of high-speed RC models with electric motor total weight of over 1 kg (F1-E>1kg). According to the world Association of ship modeling and ship modeling sport (NAVIGATION.) it belongs to the class of radio controlled. This is the most numerous class of models denoted by the letter F and a numeric index. For model class F1 (F1-V2,5; F1-V5; F1-V15; F1-E>1kg) the basic requirement to perform a “flight” in minimum time: the winner of the race, which I sudomodel showed the least course time.
