Isn’t that a stark contrast: while the fields of collective and state farms are treated today powerful “Kirov workers”, the private plots of rural workers in the old plow at best plow horse, and at worst — just dig with a shovel. This work is unproductive, time-consuming, moreover, requires considerable physical effort. That’s why many of the “homebrew” without waiting for the industry mastered the production of agricultural micro-technology, develop and produce motology and microfracture, cultivators and power hoes. In today’s publishing, you will be able to meet with the drawings and description of a homemade motor-plow, constructed a work of pumping plant VI Petruna from the village Svessa, Yampolsky district, Sumy region. Design although it did not meet all the requirements of modern design, completely reliable and fully justifies the name of metaphora.

These beautiful and flying planes is very simple. They can do and the guys who have not yet engaged in aircraft modeling. To work they need a dense drawing paper (drawing paper), a few dry and straight straws Ø 2-2,5 mm (grasses, bluegrass, wild oat), silicate office glue. Also needed is a blade for a safety razor, jig saw, ruler and pencil.
The club “Romantic” from the city of Krasnoyarsk our readers know of the recent publication (“M-K”, 1979, No. 4). The editors have received many letters with requests to acquaint them with the designs buggy club “Romantic”. Fulfilling readers ‘ wishes, we asked the head of the section of Amateur sports autostructure V. A. Hassan to talk about one of the most interesting cars.
Room model pricelet really similar to a Hummingbird. This inhabitant of South America — the smallest of the birds — have much to learn. It can still hang in the air and even fly backwards. Our model is no less maneuverable. The design consists of two polycrylic hinged to each other stabilizer, as well as double-girder fuselage, which is attached to the rod with the rubber motor. He drives the crank mechanism polycrylic. Weave wings and stabilizer — capacitor or a tissue paper.
As the history of aviation, the aircraft can be done from almost any material of the First airplanes he built from bamboo and percale, later, aircraft materials steel Yes spruce pine, them was soon replaced by aluminum and magnesium alloys, but today the high speeds require the use of titanium and high strength steels.
Held in early October 2006 from Baikonur 16th world championship flying the sport has left an indelible impression on its participants and spectators, among whom were those who real launches of missiles and launch vehicles spacecraft. To meet many requests for new sports meeting on the legendary land, the administration of Baikonur organized another celebration of rocketmodeler — held the first Asian championship on rocket-space models But given that the sport is not as popular in Asian countries like in Europe, making it open.
In recent years avtomodelisty closely watching the development of a new direction for technical activities and sports design of high-speed radio controlled model with internal combustion engine. At first they were built by high-class athletes, but now a lot of successful and budding. What are the athletic requirements for these models, and some technical data have model classes f-I and f-II?
This “bouzoukia” developed in the aeromodelling circle regional station of young technicians in the city of Murmansk. Speaking with her at the regional competitions, an eighth-grader Sasha of Beidou became the champion among students. Design feature — a fiberglass sock of the wing, much increasing its survivability.
That recumbent healthy, I think, nobody will argue. Well, for fans of technical creativity it doubly useful as it allows you to gain invaluable experience before the greater constructions. Recumbent, about which speech will go, was designed and manufactured in the workshop of young technicians (syt) of our city, together with members of the group. I must say that the idea of its creation have arisen much earlier, but because the materials and most of the parts (particularly wheels) have prepared himself, at his own expense. However, the wheels and the materials are mostly picked up from an abandoned Bicycle, so that the cost was not so great.
In a vast range of car alarms has recently introduced a good system Mongoose Duplex 3D models with the function of a pager device, remote audio message to the key FOB that the car owner of unauthorized door opening, engine start, shock the body, etc., a Distance alert in the face of massive urban development (on example of Saint-Petersburg, Russia) not less than 300 m. In the daily operation of the alarm system with a pager is convenient because the alarm comes on, the bidirectional remote control unit (RCU) is a key chain held by the owner of the car (except for a loud audible alarm in the vehicle which can be reprogrammed for quiet mode). Thus, there is no need to jump to the car or to the window each time it is triggered car alarms, worrying for his “swallow” (it is known that the set of sound signals of various alarm systems is no different variety). If it works it is “your” alarms — this will be seen by the alarm on your remote-the keychain remote, and the flash indicator LEDs will indicate a specific area of the triggered zone of protection. It agree, it is convenient.
