Probably the majority of readers, modelers had to build a model microelectrophoresis. These are good motors, easy to maintain — put it on the car, hooked up the batteries, and you can experience the new design in action. But how well able to use the power of the motor depends on the manufacturing quality of the drive. First and foremost, from its driving member connecting the motor with the mechanism. The slightest imbalance mounted on a gear shaft, the runout of the friction roller or pulley, and the engine will not even crank gear. The origins of the errors most often lie in the landing accuracy of a leading element on the axis of the armature. As a rule, planting the diameters of the parts do not match, and you have to wind on the shaft threads with glue or pull on it cuts the vinyl chloride pipe. It is clear that to talk about alignment in these cases is not necessary.

The original self-similar route, combining elements of technical creativity, sports competitions and physical training, developed a young technology of the German Democratic Republic. Its main distinguishing features — the use of motorcycles instead of a car, replacing the grooves under current-carrying copper bus and rail and, finally, the supply of power from generators installed on the bicycles.For the manufacture of the route will need chipboard or whether-ists of plywood with a thickness of 8-10 mm In accordance with the selected configuration of the “racetrack” and the dimensions of the allocated space cut strips (straight and curved) width of about 300 mm and wire them. The surface of “road” paintings it is best to paste over glass or sandpaper.
Many attract-models tracked vehicles. However, their reproduction is more difficult when it comes to making tracks. Offer the readers of “M-K” I have developed a method of manufacturing such a mover… from the tree. This caterpillar doesn’t have many joints: it consists of tracks, strung on two closed in a ring of nylon fishing line. You first need to glue a wooden profile, which is the cross-section shown in the figure. To “that will require thin strips of plywood and rails of oak or beech, its assembling is held with epoxy glue. Into the grooves better, lay a nylon fishing line — then they will not be filled with adhesive, and after curing 1его thread is easy to remove from the workpiece.
There many important components and parts to trace in the box? Yes, almost everything — so I will answer any, even the young athlete. But surely he’s really isolated from all the other current collector. It is from that little detail most of all depend on the reliability and stability of the micro-car, only on the most difficult parts of the route, and therefore, a high result.
Sectional block method of construction of the larger vessels have proven their effectiveness. It will be useful to modelers. Normally, the body size wikiepedia on the disc, is assembled from wooden slats, is made of metal, is stamped on the matrix. All these ways are good, if not one “but”… Young engineers who are building the model in ways not acquainted with the theoretical drawing of the hull. This also eliminates the collective creativity of students.
In this article we want to introduce you to one of the last successful boat designs intended for participation in endurance racing. It was created by the master of sports of international class V. Osadchiy, who took the class up to 6.5 cm3 first place at the USSR championship in 1983 with a score of 64 laps and first place at the international competition in the GDR with a score of 71 circle. Similar microtiter helped the master of sports N. Alexandrov to become the second in the match of the strongest athletes took place in Chisinau. New hull lines provide excellent course under difficult weather conditions, significant wave and wind.
To the journal is receiving increasing numbers of letters from modelers who make their first steps in the class RC. And, as a rule, one request — publish a description of the glider or plane for the initial training. Increased attention to the units of this complex model aircraft class is clear — the domestic industry began to produce proportional radio control systems, and the achievements of modern radio electronics, in particular the emergence of new circuits, give the opportunity to build a good improvised equipment. Published drawings and a description of the “flying coach”, an interesting series of design solutions that allowed to create a universal multivariate training model. It is made entirely of domestic materials.
When designing the model of the catamaran, calculated under domestic motor KMD-2,5, revealed the need to adjust speed on the radio. Had to carve out two parts aluminum diffuser carb increased length and a rotating door. New diffuser installed instead of the original, so the dimensions of the parts included in the rear wall of the housing, to accurately duplicate the dimensions of the serial. The remaining proportions are random. Note that when performing the planting hole under the flap is necessary to provide a dense enough mutual fit of these two parts. A cross hole in the valve corresponds to the inner diameter of a diffuser in the open position of the ledges at the entrance should not be. The control lever is formed by filing a thin disk, machined integral with the valve.
What processing methods but use the young technology for the manufacture of shells of rocket modeling! The most affordable and waste — vikla CA on the blank paper cylinder, master, “the one receiving a novice can just a few classes. For more complex models, especially copies, it is necessary to use a metal mandrel, fiberglass and epoxy resin. To make such tooling without a lathe, you might need it and when processing fairings models.
The appearance on the competition models of sailing catamarans and trimarans was the natural result of the development of a very interesting class of ship models — radio-controlled yachts. First I gotorussia was built in our country in 1974 almost simultaneously by three athletes from Kiev, Valeriy Bondarenko, a Muscovite Valery Efimov and the author of this article. All mini yachts was created on the basis of requirements for models of class F5-S (with an area of 0.5 m2 sail). The best results showed catamarans. In the future, on the basis of their group Kazan modelers have worked a few designs, which already could compete with the traditional single-hulled yachts with moderate wind and have a distinct advantage with strong.
