On the shelves of sports stores you can often see elegant double sledge for skiing the mountains, called “Chuk and GEK”. The sleds solidly constructed, brightly colored, very attractive in appearance, but… do not use special demand. We do not undertake to judge how good these sleds, what their shop offers, but after the installation of vasodilates D-5 and they, undoubtedly, will be a very interesting self-propelled machine (Fig. 1). Such a construction was offered by a famous Leningrad artist — N. Abramov. In our opinion, the use of sledge “Chuk and GEK” as a basis for creating various children’s trails in machine — sensible initiative. It should be noted that the possibility of their “motorization” is not limited to the offer, which did N. Abramov: in addition to wheel with spikes, can be applied to the screw or the propeller (in the latter case, it will microaerobic). Finally, why not try it instead of the internal combustion engine to set the motor power cable or contact wire?

Tractor I built out of assemblies, mechanisms and components of decommissioned automotive and agricultural equipment. The D20 engine, diesel, power of 20 HP transmission—four-speed, the car GAS-52. In the transmission there is a reverse mechanism which secures the tractor to move backwards as fast as forwards—from 6 to 26 km/h.
Designers snowmobiles operating in rural areas, and most — often used parts of decommissioned tractor Puscuta PD-10 propeller systems for their cars. It is clear and logical: the engine PD-10 is widely distributed in agriculture, it is necessary to recast it we option is not the challenge. Accumulating the experience of operating planes with such engines, the designers achieve a very noticeable increase their performance by improving purging, selection of carburetors, etc. it is safe to say that at present, a single “rural” snowmobile engine, created on the basis of the PD-10 are the most proven and reliable machine. It should be added that in the construction of chassis, control systems, etc. in recent years also created a lot. According to the editorial, timely information about these updates can assist the novice builders.
Near the base camp in the district of Tsugaru passes along with the tourists, I have built mini-hydroelectric power plant with a capacity of 15 W and voltage 220 V. This is sufficient for night camp lighting energy-saving lamps or LEDs. Day also can charge batteries of cameras and camcorders that can connect a radio or tape recorder.
“Oriole” — so I called built for the son of the electric car. The design idea came to me about two years ago, and much credit for this journal “modelist-Konstruktor”. Several months of estimates, calculations, dozens of layouts, hundreds of paintings and drawings of the body has led in the end to be quite rational, in my opinion, the solution. In the process of development of electric vehicles important issue was the problem of using abundant materials, parts and components, and as it seems, I managed to solve it.
Has long been a regular reader and subscriber of the journal “modelist-Konstruktor”. I want to share one interesting result of technical creativity. Sometimes people ask for a drawing apparatus, a photo of which is posted in social networks is decided and for this reason also more to say about it.
If the village is unthinkable without the tens and hundreds of motorcycles, mopeds and bicycles, in the Northern part of the country, where winter lasts nine months of the year, the role of these public vehicles is increasingly performed motonarty. Without waiting for the industry will be able to meet the needs of northerners, many lovers of the snowmobile technicians design and make your metal samples, sometimes not inferior to industrial.
The first development, which we publish, is a universal glider of class “Standard”, called “pennant-4”. Characteristics, it is approaching to widespread machine “Brazil”, but has a number of original nodes, that facilitate and accelerate Assembly and disassembly. The device has been extensively tested in various flight conditions. His flight main advantages: the minimum gliding angle, extended speed range, the ability to execute turns of small radius on all speed range, softness, and ease of management.
F. Slavin from the village Malesina Kurgan region gathered his hands, using the components and mechanisms of various scrapped or abandoned motor equipment.
Usually when we in the club EN-route modeling at the Tushino syt in the beginning of the school year come the newbies, they are already at the first lesson confides that they want to choose for your first model as a prototype? nail last season Ferrari, the unusual six-wheeled “McLaren” or the unthinkable, PA elegance “Carrera” GT class.
