Racing airboat engine “Raluka-7”. The journal “modelist-Konstruktor” has repeatedly told on the pages of the increasingly popular class of radio controlled racing boat with aerodiesel. Is there any need to remind them of the case differ from those created for similar models with the propeller, except that greater width, however, the design of the power unit with the propeller not in the example easier. So, for aerolister not required technologically sophisticated gear reducer, it does not need water-cooling system motor and transmission drive propeller. All this greatly facilitates the work over the model and, consequently, makes it available for production, even for novice athletes.

The idea is to make a mini-tractor ripe at once: an allotment I have a small, but because I was without equipment. In General, it was more a desire to test their capabilities. In the garage by that time had accumulated suitable assemblies and mechanisms. So, the wheels gave me friends (they have many years of lying idle) and the engine gave a friend, because I helped him to restore an old “Moskvich”.
In Moscow in the yard of the house № 11 on the 2nd Schukinskaya travel can often see the most incredible car designs, which are operated by boys and girls. And the amazing thing is that all this micro-technology they themselves have built. And the center of gravity of the infantile population of the yard — children’s technology club ZHKO research Institute of inorganic materials. Interesting about the machines that are created here, we are told in No. 9 for 1974 and No. 6 in 1975.
Oddly enough, recumbent… older bike. Its ancestor can be considered the original “self-moving carriage” proposed by the famous Russian inventor Kulibin in 1791. On her back, at the back, stood the servant, pressing down on the levers and spinning the two horizontal flywheel.
This universal machine with a capacity of 2.5 t built Ustinovich V. S. Stern Rostov region the engine of the machine from the tractor T-40: diesel, 4-cylinder, air-cooled output of 50 HP Frame from the mobile pumping stations, bridges and rear wheels from GAZ-51, the front wheels from mnogolemeshny plow, transmission from GAZ-53. Dump body and a manipulator with a lifting capacity of 1,5 t — homemade.
There is a perception that sailing is a lot of people with high incomes. Of course, in relation to racing dinghies and cruising yachts, this is largely true. However, from a small homemade ahtoska you can get no less pleasure than the solid cabin of a sailboat, the more it will cost you significantly less.
The hinged trailer was manufactured and installed on the tractor MTZ-5 (Fig. 1). Figure 2 shows a diagram of the tipper Assembly. Its main parts: a support frame body, weld metal landing frame and precast plank exterior.
Guys living in rural areas, and many urban students know: before posting to the Elevator, harvested grain, until dried, stored at currents in piles. However, long contain so harvest is impossible: because of the increased humidity may increase the temperature inside the piles, and the grain will spoil. To avoid this, it is shoveled (inner and outer layers are reversed). And the time when the grain begins to overheat, determined by its temperature and humidity.
With this proposal, despite the well-known skeptical saying, our magazine appealed to readers in No. 6, 1969, published a compilation about some unusual designs and a description of the bike S. I. Gorshkov with an additional manual drive on the front wheel.
These guys have a lot in common. They all live in the Serpukhov district, their parents — farmers. But most importantly — they are all involved in the circle of technical creativity of the regional House of pioneers with the wonderful teacher Yevgeny Diligentia.
