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.

Preparation of feed for Pets will go much faster with electrothermy. Five minutes turns out two buckets of chopped vegetable mass — juicy supplements to straw, the Seine and other dry food.
Journal with drawings of Cordoba aerolizer who have developed a record speed, took all the guys from our club. “We will build these!” — without hesitation, they said. To dissuade the boys did not want, it is better not to do it when tempers flared. But the excitement gradually subsided. As usual classes were, and, trying to repeat superconstructor my players became a little “sour”. We have little idea the boy would have ended up with nothing…
Among novice modelers-korovikov argued that in the manufacture of teaching models overly bother not worth it — still the aircraft destined to endure at best a couple of flights. Well, can’t argue with that: indeed, clumsy, carelessly made and poorly assembled control line plane finished its flying service at times on the first laps on the track.
Commercially available baby cots have a significant disadvantage: though they have wheels, but to move the cot from one room to another uncomfortable.
