My walk-behind equipped with two knife cutters, soil processes, and after replacing them on the wheel turns into a tractor trailer truck with capacity up to 300 kg with a weight of 60 kg. the Size of power tillers is also small: height — 800 width 420, length — 1200 mm (with folded handlebar is 600 mm), so it easily fits in the trunk of the car. The engine of the scooter VP-150. The start is a kick starter, gear shift lever.

HORSE — RACING
Control line racing model airplane that we want to bring to your attention, fully complies with the requirements of the FAI. Its most important characteristics: minimum total area — 12 DM2, height with cab — 100 mm, the area of the midsection — 39 cm2, the fuselage width — 50 mm engine capacity — 2.5 cm3, fuel tank capacity — 7 ml.
SNOWMOBILING: WHERE TO START?
To the editor of our journal continues to receive many letters from Amateur designers: the interest in such type snowmobile technology among different age groups continues unabated. But the character letters often suggests that many builders begin manufacturing snowmobile, not very clearly imagining that they want to build and what the machine can see the future, why you want to work with. Naturally, because of this allow annoying mistakes, and end up with a design without the desired operational and technical characteristics.RC AEROBATIC
For eight years I worked as a head of the aeromodelling circle at the station of young technicians in the city of Kiselevsk of the Kemerovo region. Himself in his spare time build a radio controlled model aircraft class S3A. I will provide the fellow training model aircraft aerobatic model.STARTER MOTOR
To run the motor manually? And fingers will discourage, and not always with a half-turn wind up cranky diesels. And the competition time limit to run very hard. Did not fit in the allotted minute — and-goal instead of numbers in judicial protocols appear null.THE WINNERS OF THE PILOT CLASS
In the summer of 1981 in Moscow took place the traditional competition for experimental model airplanes. Today we introduce you to models — winners of these competitions. Student A. Bobrov from the city of Khimki (Moscow region) constructed a model glider “flying wing”, which showed at the competitions best results. Over five rounds were demonstrated following the duration of the flight: 81+16+28+180+130 = 435 C.THE NEEDLE WILL NOT BREAK
Many advantages in this model of micro-motors of the type “meteor-2,5”, CSTOM-2,5, “swift”, “Falcon” and the like — with front-wheel distribution. But, installing them on the model of air combat or training, you go at some risk. The fact that a failed planting of the motors, as a rule, the needle breaks the needle valve or, even worse, damaged the nozzle.THE FUNICULAR TO THE SKIER
For tourists and skiers in big mountains with difficult terrain and significant elevation usually put a chairlift. At its traction-bearing rope they have special hangers with one or two armchairs. The length of such lifts is limited to 1.5—2 km: experience has shown that the rise in excess of time 10-15 minutes, can during winter lead to trouble — frostbite unprotected skin, especially the face.MODEL ROCKET GLIDERS
Category S4. The rocket plane is an aircraft that is lifted into the air using the thrust of the rocket engine, and returns to earth planning with the engine off — using the aerodynamic lifting force. This requirement applies to all three categories of rocket gliders for the duration of the flight — S4, S8, S10. And each has its differences. S4 — model glider with an accelerator, which can be separated during the flight. S8 — model RC rocket glider S10 — a model rocket with a soft wing (wing “Rogallo”).
“GENTLE” REMOVER
As you know, in a two-stroke motorcycle engines bearing-connecting rod is one of the most loaded nodes. At the same time, its technical condition depend on time and the quality of the engine. To determine the wear and furthermore make the necessary repairs without dismantling the crankshaft is almost impossible.
