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.
HIGH SPEED “BABY”
Lately 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.
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. 
German 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.
The driving force of the engine during the flight of model airplanes, aerovision or aeromobile is the thrust of the propeller. The quality of the workmanship and clarity of the selection of the propulsion depends largely on the General characteristics of the constructed model. It is therefore clear that the design process of the propellers is paid maximum attention. However, the calculation methods of the selection of propellers is highly intricate, time-consuming and not very accurate. Today we recommend a number of well-established screws, already tested on a mass micro-motors internal combustion.
