We have already talked about the agricultural arrangements, where the engine used electric mowers — rotary and shearers knife (see No. 9 of 1980, No. 2, 1981), plough on electric (see # 9 in 1981). Now offering new construction on the same basis — the cultivator of the soil. First, obviously, you need to explain why I designed the mechanism, the main purpose of which is plowing and this scheme — in the form of electrodyalisis. Why not go for more or less beaten path, taking up a walk-behind plow. First of all, it dictated the small size of the treated area and high density of planting tillers are simply not to turn around. Then had to take into account the weight of the guns and power, developing a medium amount of torque just 3 kg. With this machine will easily cope and teenager and woman, and elderly people.

What models of gliders was not in the sky above the sports airfields! Short-tailed side by side with these, whose stabilizer it seemed unreasonably far related from the wing, the search of the optimal elongation of the supporting planes of the transformed outline of the airframe in the likeness of a flying ribbon, brachypterous, such aircraft unit. A few years ago, athletes arrived to a common opinion. Although each scheme had its own advantages and disadvantages, experimentally found the best dimensions that satisfy the conditions of soaring in thermals, the flight in a calm atmosphere and in a strong wind. Parameters recognized compromise (wingspan 2000 mm, chord 145-150 mm, shoulder 700— 740 mm), provided smooth, very good results.
The first flight of kites I started to build in 1978. Dozens of options are made over four years, helped to define the tests, experiments and subsequent revisions to the best form and arrangements of the wing, to learn the subtleties of the serpent and its behavior in various conditions. All this allowed the “Acrobat” to become a highly maneuverable aircraft with high aerodynamic characteristics. Its design is highly durable. Snakes can fly in any weather, he’s good and confident performs aerobatics in almost any wind (4 to 16 m/s).
Good motorists! Easy turn of the ignition key and the starter turning the crankshaft starts the engine. Of course, we do not encourage modelers to install an electric starter on the motors. We will focus on stationary unit intended to significantly facilitate the launch of the compression and glow model engines. He will provide you great help in training and in competition where the engine run time is extremely limited.
This double, the saloon car is undergoing testing. Its main units and components taken from production cars and motorcycles: engine power systems and equipment, as well as wheels from scooter “Tourist”; dampers front and rear suspensions from a motorcycle “Java”; a steering mechanism from “Zaporozhets”; rear brake of the scooter “Electron”.
Wheeled ATVs (all terrain vehicle jokingly called the homebrew “karakachani” or “Rovers”) on low-pressure tires (often referred to as the “Pneumatics”) is a very popular car among designers and enthusiasts. However, the high complexity of manufacturing the wheels, and most importantly — the low reliability of their tires (usually made of cameras wheeled tractors) are often cool creativity of the craftsmen. Meanwhile, a tyre for wheels of such a vehicle can be made of the right tire (diagonal fiber cord, not torn and not quite “bald”) from the wheels of a truck or wheeled tractor.
Despite the widespread use of electric refrigerators, such building, as a cellar, do not give up their positions. Especially in rural areas and in suburban areas, where in these, prudently organized, compact storage with a good waterproofing and skilfully chosen ventilation is still not forgotten to maintain the desired temperature and humidity conditions, and favorable conditions for savings products that do not rot and does not shrink, without losing its unique taste and smell. However, if used the most common was free-standing cellar, today in order to save area, many prefer the compact storage of vegetables, fruits and homemade food, is equipped with a summer kitchen, a barn, a garage…
Offer simple, proven in dozens of models of the design of mechanisms to control the stabilizer and rudder for time or rezinomotornaya models. The basis of the first node is duralumin bracket designed for fixing horizontal surface of the empennage on the fuselage, and ensure its deviation on the horizontal axis. The vertical shank of the bracket is wrapped with thread, is inserted into the groove of the fuselage and secured with glue.
The Internet has no boundaries and it brings people together. Especially like-minded people. On the website www.minitraktor.Ork.ru user under the name сеnteur from Lithuania is presenting its all-wheel drive mini-tractor with “broken” frame, which has been in operation for twenty years. The engine it — UD-2M. Gear shift — from a motorcycle “Dnepr” and 2-speed gearbox with neutral position — from the old blower to provide mini tractor with eight speeds forward and two back from 1 km/h to 17 km/h.
