WALKING RECUMBENT

One of the main sources of environmental pollution is the vehicles. Therefore, constructors have a natural desire to create alternative, environmentally friendly means of transportation, which fully applies and recumbent. As the basis of its development, we adopted the design of the velomobile V. Mazurchak (“modelist-Konstruktor” No. 10 of 1987). But the technical capabilities are not allowed to repeat the machine one to one, we are particular to this and not sought. Besides, from the point of view of “strength scientists”, analog velomobile is, in our opinion, not very successful scheme of loading the important elements: the junction of the front and rear parts of the frame and the axis of the rear wheels, which can cause breakage of parts or assemblies during operation. But I wanted to make the car reliable (and therefore is durable) and thus to meet at least 20 kg of weight. The velomobile was to have such dimensions that enable it to pass under a standard door of the apartment and fit in a regular (not cargo) lift. Well, that was easy to transport and store, wanted to make it more collapsible.

UNMATCHED AVIATION

Today we continue the theme begun with the publication of non-traditional polyopia supersonic fighter-interceptor MiG-25, the New development even more unusual in the choice of the prototype for the copy and overall design of the model. Today, it is about the reproduction in miniature of a legendary airplane “Voyager”, made in 1986 by flying non-stop around the globe. I hope that ego of publications will contribute to the revival of some extinct interest to the class “school” sports polycopy. It should again be noted that Voyager, like the MiG-25, only a single instance of a large number of interesting prototypes, giving modelistica up at any level.

MANAGEMENT OF GAS — ON THE RADIO

There is a perception that control the “gas” compression of the motor as well as nitro, is almost impossible. However, for a long time had already been quite successful systems for remote control of frequency of rotation of the shaft diesel. Failure, usually associated with the specificity of modes of diesel and errors in the design of standard mass carburetors of the motors. Such subtleties on the proposed material, telling about the alteration of the compression of the engine under remote control.

“SLALOM” SLALOM

Someone had to ride on a sled, knows that the particular manoeuvrability from them should not wait: in the best case they can be deployed on a steep slope, but changing the direction of movement of the sled is not easy. Meanwhile, the sportsman-the mountain skier could turn with ease. And the reason that skier unlike the Luger can tilt the skis: relying on steel edges, they can easily enter the curve, allowing the athlete to move on their chosen path.

SKIING IN THE SAIL

The desire to ski “with the wind” makes us resourceful athletes to invent a new sport: racing on skis towed behind a motorcycle (skijoring), boat and even horse. Today, it seems we are on the verge of “opening” another form of skiing-a tow sport where the athlete has to match the skills of the skier with the ability to manage a sailboat on the tires with very low pressure. Such towing is already popular among fans of winter tourism, as they allow us to travel long distances without special effort on the part of the athlete.

THE WEATHER CONDITIONS AT THE START

Assigning the date of the training and competition of air or rocketmodeler, to provide almost everything: minutes to paint the starts of models of various classes, to provide participants with food and accommodation, provide them with transport service… the Only thing that it is impossible to foresee is the weather. However, the weather factors equally affect all participants, and the advantage is given to one who has knowledge of the conditions of the zone flying, pony manius physical basis of weather processes and their ability to make a competent assessment.

ONE WAY IS DIFFERENTIAL

The need to have in personal possession a nimble and reliable metabolomic I (as probably many others in a similar situation) keenly felt, when he became the owner of a suburban area. On a mini-tractor of forces and means is not enough, therefore, decided to limit tillers, focusing on development that are found in binders “Modeller-designer”. The matter came creatively. As a result, fortune, which is published in the “Panorama” (“modelist-Konstruktor” No. 10 of 1984). Collected for the first own hands a cultivator followed by a second, third… And now the fifth, successfully proven in practice design (Fig. 1).

RUBBER-ENGINE CHAMPIONS

The attention of all the adherents of the popular throughout the world class Ф1Б — rezinomotornaya expense of building a traditional model — we offer unusual today as on the content and orientation of the material. In it you will find detailed information about the almost unknown among Russian modellers school of design. We all have long been accustomed to the fact that championship technique is distinguished not only the highest flight data, but, as a rule, unique and complex design and manufacturing, in fact, irreproducible at the level of the capabilities of the average modeller. The proposed school, with its refined simplicity equipment is able to provide access n the heights of excellence almost everyone, regardless of their security or ability to make arrangements “space” of complexity and accuracy.

SHOWER FOR CAM

Engine classic Vase (2101 -2107) is very reliable and durable unit, easy to operate and easy to maintain. However, he has his own “Achilles heel” — the camshaft, it is highly suffering from the so-called oil “starvation”, which occurs sometimes in well-warmed-up engine in two cases: when the oil is thoroughly liquefied, or when badly worn out oil pump and other components.

AIR BENDS

Young conovici-only pilots rarely taken for the creation of highly complex models. Basically they design a simple and feasible model of universal definition, which are equally suitable for testing of flight control avionics complex, and for competitions. We must remember that half of success on the performances of only pilots — the run-in, reliable motor. More suited KMD-2,5 and MDS-MDS or a 3.5-4 in export performance. It is simple, technological and, most importantly, “volatile” model — is proposed for the attention of young korovikov. Pilotage designed based on the available materials instead of lime for many parts, you can use high quality blanks from aspen, alder or poplar.
