Every year fewer and fewer aircraft with piston engines. Lightweight, economical running on cheaper than gasoline, fuels, jet engines replacing piston even from agricultural aviation. But in any aeromodelling competition still reigns “piston era”. On kartodromo you will see the masterfully made copies of “Ilya Muromets”, “Nieuport”, I-15, Yak-3… do Not attempt to only search for a model jet aircraft — the era of rapid modern machines in modeling has not yet arrived. The reason is the lack of jet motors or at least their imitators: piston motors with impellers. Unfortunately, numerous attempts by modelers to create quasirational the engine was not successful — usually these devices have extremely low efficiency and did not develop the thrust required for steady flight of the model.PISTON — JET

Jigsaw is perhaps the most popular tool in the home workshop craftsmen, and in the laboratory modeller. Meanwhile, its design has remained unchanged for decades, but this does not mean that it is perfect.
With all its advantages of an inflatable boat of any design has the same General disadvantages: Shorty wislica, turtle speed and bad handling. From all of them at once we managed to get rid of, adapting your boat “Dive-4” under sail: with him she became and the faster and more manageable. And actually upgrading was quite simple and compact, that is blended with the amenities characteristic of inflatable boats.
My tools are designed for processing of soil in the garden and the vegetable garden. The main type of work in the spring and summer — preparation of beds for planting and care of plants. Therefore, more than a third of the set are rippers. They are divided into three types: one-, two – and trehrozhkovye, and each is used depending on the planting density and the soil conditions. Where gaps between plants are great, easy to work trehrozhkovye — they are the most productive; and where planting is thickened, handy slowly loosen the ground two or odnokrylym.
Build model rockets. The first manned flight into space, our compatriot Yuri Gagarin in 1961 was the beginning of a new the directions of technical creativity — rocket-and-space modeling. And from the first steps of this interesting kind of design magazine “modelist-Konstruktor” became its active promoter and popularizer. And loyal to him until now.
In the soul of every boy living Navigator, so any rain brook — is a river, and a large puddle is a sea calling out to let the boats from the simplest of chips or a sheet of paper, to specially planed, and the more such combined, as proposed by the German magazine “Technium” self-propelled model of a boat. Yes, no ordinary boat, but an old, two-pipe, with paddle wheels at the sides. What child would not want to build like this, especially because the design is quite affordable for independent playback.
Australian Steve Sammartino (Steve Sammartino) and Raul Romanians Aida (Raul Oaida) presented the car on the pneumatic actuator, assembled from parts designer LEGO. The car accommodates two adults and is able to accelerate to 32 km per hour. The construction of the car took half a million of parts of LEGO. From the designer collected all the parts of the machine, including four runs on compressed air piston engine. The only elements ostavlennye not LEGO are the wheels, tires and instruments on the panel of the driver.
They are large and small, foldable and “monolithic”, table and floor — the different designs, but with one common shortcoming: require space for storage. We are talking about Ironing boards. Indeed, so necessary for each family household goods, and such an archaic, “clumsy”! where to clean it up when all the sheets are in order? However, came to light and the modern Ironing devices going, so to speak, in pace with the times scientific and technological progress: electric units in which instead of heating the iron bar, and the role the Board performs a cylindrical roller. But this construction is even more difficult to attach in the apartment so that it had not violated the interior.
