Two people who moved in Russia “underwater thing” off the ground, deserve a separate story. Chronologically, the first was Ivan Alexander, teacher of drawing and painting, always interested in modern techniques and technologies. Once in France, Louis Daguerre invented a usable method of capturing images, which subsequently became the photo that Alexander immediately made acquainted with the method and opened in St. Petersburg, a photo Studio, one of the first in the world. It is this passion that became a profession, and brought the inventor to the underwater case.

The first little micro-car “mouse” I built for my kids. As a result, I accumulated some experience of designing and has already planned not as a child, and “adult” car. Called it “mouse-2”. Built a long time, or rather, not so much built, how many were looking for the necessary parts. This, in particular, due to the use of “Mouse-2” mechanical brakes (now I change them for hydraulic). Design drawings and the construction was carried out simultaneously, although the basic parameters of the “Mouse-2” was thought out by me in advance.

Usually, it often happens that the outwardly unprepossessing models-silhouettes start your journey in technical sports boys. After one or two procopii, they are taking with them part in her first competition and… don’t remember about contour, as we approach a much more sophisticated technique. Therefore, it is rare silhouette microcodable worthy of attention: because most often they come out from under too inept students.

Living in the age of technological progress, a wide range of machines and tools, we sometimes underestimate the technical ingenuity of our ancestors. Meanwhile, they used mechanisms and adaptations in design is surprisingly simple and rational.
The results of the last three meetings, which were attended by hundreds of aviation enthusiasts, showed that the majority of the devices is executed at a high professional level. But there were planes, which the creators clearly lacked basic knowledge and experience. These machines, made in violation of the laws of aerodynamics and theory of strength, to fly is not allowed.
The design of the rack, as can be seen from the drawings, is extremely simple: it is an open shelf mounted on vertical uprights. Assembled with glue and bolts. For the manufacture of one shelf the desired strap section 25Х50 mm length 850 mm (2 PCs), 872 mm (2 PCs.) and 200 mm (2 PCs.). They have to be placed so that the longer it was in the middle, entering into the gap between the vertical ribs, having a length of 2000 mm and a section 25X50 mm.
