HIGH SPEED “BABY”

HIGH SPEED Created in our circle of control line speed model aeropittura school of a subclass with an internal combustion engine working volume of 1.5 cm3 the diagram is for a rarely used “asimmetrik”. In its construction—a number of technical solutions which allowed to improve starting (which is very important in the environment of the model newcomers) and performance. So to facilitate germination on a wave at lower than championship technique speeds the length of the nose redan decreased, while the angle of attack is his “sole” in the back work area a bit increased. Absolutely unconventional technique — Vegas the front edge of the redan on the corner about 8′ in the view of the model from the front. This solution ensures a reliable start, eliminating incorrect even with the cast time of the glider inside the running circle (hydrodynamic lifting force developed on the “sole” of redan, has a component directed towards the left side). In addition, an important factor of removal of spatter from under the redan on the right side, that is away from the disk rotation is offset to the left of the propeller power plant.

FLYING IN THE RAINBOW SPRAY

FLYING INTO THE RAINBOW SPRAYLately becoming more popular competitions on water-motor sports. The exciting drama of racing racing colorful boats, iridescent splashes of water, enthusiastic audience! RC racing boat are not less popular among athletes of all ages. The design of such micropolygon simple. The model is quite well-known motor type “Mabushi-540” equipped with a two-bladed propeller with a diameter of 35 mm and a step 47 mm. To power the installed battery 7.2 V/1.2 A*h Nickel-cadmium elements. Management — with two-channel proportional equipment. The engine speed change by the speed controller and the direction of the path of movement of the steering machine.

ROCKET FROM BIYSK

ROCKET FROM BIYSK

Raketoplana this scheme, the athletes received the name “Moscow” in the building today, everywhere that speaks about its high aerodynamic qualities and reliability. However, each rocketmodeler trying to bring in design and something different, getting this sometimes with interesting results. It was developed a model athlete from the Altai city of Biisk Alexander Puzikov. Based on the “Moscow” scheme, he increased the wingspan rocket glider and the length of its fuselage. And, as shown starts at the Russian Championship of 1996 for model rockets, the innovation has justified itself.

STAR — CONDUCTOR

STAR CONDUCTORAmateur Designers often used in the transmissions of their cars, the chain transmission. And sometimes faced here what problem: for the calculated gear ratio chain couples find it difficult to choose ready-made sprocket with the desired number of teeth. But them it is possible to make yourself using the jig, assembled on the basis of the gear closest to the desired amount. Suppose you need a sprocket with 26 teeth and pitch of 19,05 mm. will Select the gear with the same or similar number of teeth. For example, 27. (In this case, the gear ratio will change slightly by 4%.) The gear is hardened, has a thickness of 19 mm and a bore diameter of 20 mm.

POUNDING, SO GOOD!

POUNDING, SO GOOD!Many models can be made to forgotten the method, by squeezing the sheet metal. Extortion is used for any thin-walled parts (e.g. fairings, cowlings, shrouds, wings, wheels, and similar). Often they are made of brass or aluminum alloys. The material is pre-annealed with a pair of scissors and cut the workpiece with considerable allowances. The tools serve as a mandrel, anvil and various hammers. The process of knockout s is the stretching of the material when its thickness decreases, and in the sediment, which implies an increase of the thickness.

FLYING WING “JUNIOR”

FLYING WING

In our circle beginners-students who have gained initial skills training cord model engine MK-17, traditionally entrusted with the Assembly of models of air combat with the same engine. In this sports class is most often used layout type “flying wing”: lomikami wing and Elevator on the trailing edge of the wing. Spar-wall this model is made from spruce, pine, aspen or lime plate thickness of 2.5 mm, and the rear edge of the wing—rails section 12×3 mm. the Latter consists of centroplane and console parts. Joints edge definitely wrapped thread and impregnated with glue, or with rough landings inevitable failure. The wing tip is made of plywood or wood plates with a thickness of 2.5…3 mm is recommended to facilitate Their holes. If the rib is cut from plywood, the edges are not required.

FROM THE RIVER TO THE SLIPWAY MODELER

FROM THE RIVER TO THE SLIPWAY MODELERGerman river motor yacht “bar-new” (Warnow) was the inspiration great procopii, equipped with an electric motor and two channel radio control equipment. She was repeatedly reproduced by modelers and enjoyed great success at competitions and demonstrations. In the absence of radio equipment with the model it is possible to speak in the classroom “bramahadev”. The design model is simple. With its manufacture and Assembly can handle every aspiring constructor of ship models. The case is of classic design, stacked wooden. Collect it on the epoxy. Mounting up the keel on a flat Board-berth with a fixed drawing with the layout of the centerline and locations of frames from the 1st through the 6th. All of the parts of the frame previously marked in accordance with drawings, cut out and treated.

RADIOPLAYER: HOW TO FIND THE OPTIMUM

RADIOPLAYER: HOW TO FIND THE OPTIMUM

Now we can safely say: RC model become the most popular in our country, turning from an object of elite hobby at a relatively affordable hobby for many athletes. The reason for this is the emergence of both simple and complex, and most importantly — reliable control equipment. Now, according to experts, the number of “cordovil”, “svobodnoradikal” and “radio operators” as a first approximation, equal. More important was the question of where to start entry into the most difficult class RC. The theoretical directions and schools here, there are many. But. it seems that there is no more reliable and “bloodless” (the number of broken during the development of radiobiology models) than the traditional, based on a gradual transition from simple gliders to more and more complex motor vehicles.

“BEETLE-42”: THE TRANSPORT OF HEAVEN AND EARTH

From experience we know that the appearance of ultralights “beetle-42” generates a lot of emotion and, of course, questions. Emotions lower, and all of the many issues leave one of the most significant: why is he not three-, and four-wheel chassis? Before you answer, remember that a vehicle with a tricycle landing gear and a forward driven wheel is unstable on turns and uneven ground and prone to rollover. The same can be observed in three-wheeled Beltelecom in the most critical modes of operation — the landing. And especially on unprepared sites. As practice shows, from tipping there, no one is immune: not a beginner, nor a master.
