Not just once or twice I had to dig up waterlogged clay soil at the site. The earth clung to the shovel in such numbers that further work without purification was simply impossible. Remove soil from tools, too, was difficult and took more time than the digging.

A MOTORCYCLE INSIDE THE WHEEL

One-wheel motorcycle that is not afraid of off-road, constructed in the village of Yanino in the Leningrad region Eduard Melnikov. A four-foot wheel of a car rolls freely through meter pits and ditches, he does not mind the deep snow and small shrubs.BRONZE MEDALIST OF THE WORLD CHAMPIONSHIP
It has long been noticed: the pilots, even the most beautiful aircraft, whether it’s a huge “Boeing-747” or fast and agile MiG-29, never refuse to fly on UltraLite if they are given the opportunity. Paradox? Not at all. Most likely, only in the cockpit unprepossessing at first glance, the ultralight aircraft they are fully able to experience the feelings that accompany a free flight.SNOWMOBILES: IDEAS AND DESIGNS
Alexander Mikhailovich Zavorotny lives at the station of INTA, near the Arctic circle. In the field of technical creativity, he is no newcomer. He has several original designs snowmobiles and motonarty that he is constantly improving.BOAT-AMPHIBIAN “SWALLOW”
The idea was truly grandiozny is to design and build a versatile vehicle, able to move confidently off-road (land version) and be speedy and reliable afloat (boats). After a few years the boat amphibian was ready and passed first tests. Started normal stage of refinement, enhancements, improvements, ride quality and handling. In between working in the garage was the shows long passages, test runs in road conditions and water crossings.CLASS “A-3” the mass is, the skill will be!
This is one of the most heavy and high-speed models. It belongs to the class “A-3” according to the Rules NAVIGA. The model consists of the following main components: hull, floats, motor (10 cm3! with shaft, propeller and fuel tank. Hull and floats are made from a light and soft wood, preferably balsa.THE BIKE CHANGES SHAPE
This is another publication about new ways of use of the Bicycle the inventor, V. M., Gavrilova — the inhabitant of settlement Inozemtsevo area of Zheleznovodsk in Stavropol region. Previous publications in magazines “modelist-Konstruktor” No. 10’97 and № 5’2000
RIGA SOUVENIRS
Great interest of young innovators, professionals of various industries has caused organized at ENEA USSR tematicheskaya exhibition “Inventors of Latvia — production”. And especially the fact that she showed an interesting experience of “planning” inventions accumulated e Republic, there are organizations pioneering the search on the most pressing, important for the national economy problems.ROCKET-SURVIVOR
The proposed model has a classic pattern glider A-2 “Hawk” in a reduced form. The main material for its construction – balsa. I must admit that over the last three or four years, such constructions appear frequently in competitions of any scale (though the schoolchildren they are made of more affordable material – to-ceiling foam). A return to this scheme due to the stability of the flight of such a rocket plane. Except only on the runway (starting) station.
Takeoff without… spiral
The competition rules for models raketoplana prohibit use for take-off surface, creating aerodynamic lift. Flight model can be scored if, at the time the hoist is used only reactive SIPA engine.
