The idea is to make readers Boer came to me in the following everyday situations: having descended into the manor house, did not have time before winter to conduct water from the well. Dig the same trench though not long (about 5 m), but fairly deep (about 2 m) in the frozen ground seemed difficult. Not to wait for the next summer, I decided to drill a little below the freezing depth of soil horizontal borehole (the borehole of relatively small diameter) for laying in it steel pipe in 3/4″ for the supply of water from the well through the underground to the house.

10 years have passed since the moment when on the ice kartodromo countries started regularly played the championship of the Union and the RSFSR. In the winter competition includes two classes of racing and two classes of models-copies of planes with compression engines of 1.5 and 2.5 cm3. Today’s theme is the racing model of the sleigh, their schemes, design features, propellers, etc.
This schematic model airplane designed by M. S. Stepchenko, one of the veterans of the Soviet aircraft modeling. Its main advantage — ease of fabrication. Required for construction material: pine rack, a little steel wire Ø 0.6 mm, tissue and drawing paper, rubber thread Ø
Laboratory and technical creativity SGPTU № 33 at the Leningrad Association “Svetlana” is already known to our readers. Dozens of original designs, has earned diplomas at many exhibitions, inventors ‘ certificates, rationalization proposals introduced, giving a substantial economic effect, the laureate of the medal is the result of the work of LTT for several years of its existence.
Lately in the aviation modeling widespread flying models, radio controlled, including helicopters. For the first time such a model was demonstrated in 1959 at the all-Union competition of S. Vorobyov. To control the flight he applied the principle of changing the alignment of the apparatus. After a year in the championship, in the background, a helicopter appeared Borisov with an aerodynamic rotor drive. In 1964, at a match meeting of the athletes of Moscow and Leningrad, he introduced the concept of B. Yuriev new model with tail rotor. However, the car was “raw” and, unfortunately, remained unfinished.
The best Amateur-built glider, took part in the competition “Dombai tops” in 1978, was named “Sokol-2”. Its Creator — Leningrad master of sports V. D. Mikhailov, a renowned specialist in the design and making of yacht sails. So it is understandable his desire to use when constructing the glider, the latest achievements in the field of sailing. As a result, the quality of the dome “Sokol-2” had no equal among the devices flying over the Caucasian peaks.
The fuselage of modern rezinomotornaya model aircraft usually consists of two parts: the power (it houses the rubber motor, is attached to the lug screw, wing) and the tail boom carrying the tail surfaces. The power part usually is a thin-walled pipe of aluminium alloy, plywood or fiberglass. Tail boom made in the form of a light truss or stacked monocoque construction with hard balsa covering.
