It so happened that almost all the children’s toys with a muscular drive — pedal cars, maps, bikes — designed for use in main leg muscles. And almost none of these machines work the muscles of the hands. It is in vain, since the movements resembling, for example, rowing, at the same time would be included the muscles of the arms, shoulders and back. Such actions also contributed to active pulmonary ventilation. All this prompted me to design and fabricate for my son “Roller”-muskurahat with manual transmission.

The garden in the garden requires constant attention and care. But if the issues of timely tillage, planting and fertilizer application depend primarily on the diligence of owners, the need to maintain optimal soil moisture is dictated mainly by natural factors. The arid climate of some regions of our country requires an additional daily irrigation of family land. This condition becomes crucial for obtaining good yields.
The basis of the hive — a column with tap holes on the front doors on the rear and a slider on the inside of the side walls. On the slider rest seven light plywood cassettes with cellular framework. For inspection and replacement of frames of the cassette may be made removable metal table. Top and bottom of the column access block tick the honeycomb lattice, from the weather hive covers shed roof with ventilation slots.
Compaction of the soil. It occurs, as is well known, not only as a result of systematic effects on the earth-wet nurse of heavy machinery, vehicles, but also because of natural causes. And ultimately leads to large losses in productivity, reduction of soil fertility.
Meditating and finding equipment for the new sports season, we decided to stop on tested, proven for many years solutions. Sacrilega scheme is not too large wingspan; horizontal tail with stabilizatory part and Elevator… However, the latest publication in the “M-K” made us much more attentive to the consideration of the moments of inertia, and therefore the maximum relief of the tail section, respectively, projected for a very short bow, load-bearing engine. With the usual for pilotaggio measurements was “obladis” — because in the design model, greatly influenced by the shape and length of the nose of the fuselage. However, this problem we managed to solve due to the unusually long chassis fairings. With them the model is not only advantageous to look at the ground, but in flight is not inferior in the perception of long-nosed cars. Benefit appearance and is the simplest closure of the plant verhneraspolozhennyh shields (in the bottom of the engine is completely open), and a large spinner.
Of most interest to the weather reports for tomorrow show… motorcyclists. Indeed, unexpected rain or, God forbid, snow transform trips on a two – or three-wheeled cars in torment. While it is not so much the driver (he knew what was going on, getting open to all the elements the car), how many passengers. Even in a side trailer can’t hide him from the weather troubles. That is why many motorcyclists are trying to solve this problem, creating on the basis of the serial side of the trailer closed cockpit with a particular level of comfort.
Since 1987, entered into force new “Rules for flying sports in the USSR”. Changed and technical requirements for model rockets. So, in the category B4 (model raketoplana) one of them says: “In the case of models with a flexible wing of the planning part should be more than 50% of the starting mass of the model”. As practice shows, the innovation did not deter the athletes from the construction of miniature gliders, forced to look for new ways of their technical improvement. In our opinion, taking into account the new requirements are a very promising model with Delta wing, designed by athletes from the Moscow city Ramenskoye A. Levin and I. Prikhodko.
The work of our circle of technical creativity at the Polytechnic of light industry does the city have repeatedly told on the pages of “M-K.” At the last such publication number 2 for the year 1989 drew attention to the gas company from the village of Urengoy and Tyumen region appealed to us to develop and manufacture universal all-terrain vehicle. They needed a reliable and easy-to-use machine, with its high traffic, quite comfortable conditions for the members of its crew, as well as buoyancy.
“It’s been fifty years since I work as the head of the aeromodelling circle in syut. Now faced With great difficulties: no aeromodelling materials; if the sets and be available, by type of disgusting quality, and made models don’t fly. Students were little interested in the sport. Beginners have the patience just at the beginning of the construction of a complex model…”
With the magazine “modelist-Konstruktor” I’ve known since high school, often picked up from the magazine interesting ideas, implemented them. Over time, accumulated their own experience, appeared and their development. One of them I want to offer to the readers of “M-K”.
