In the last ten years, model Aeronautics-members syut G. Votki claim with the same success at the national competitions held by the Ministry of education, repeatedly winning prizes. Particularly well the boys compete in classes rezinomotornaya and timer models, where every year they become Champions of Russia. A large proportion of the success belongs to an unusual school design winged vehicles, which were developed in the aeromodelling circle suit.
Before you start the story about our new model of class RM-2, we want to go back a little and to remember with gratitude the publication in “M-K” № 5 for the year 1991, which was the first time in the practice of automodelisme describes the main design principles rezinomotornaya. It should be noted that many of the points of the article for us was, if not a revelation, then at least unexpected. This is especially true of the exploitation of the rubber motor harness, a choice of parameters of the chassis and check the nature of the motion models in the boost areas.
Cultivation, furrows, weeding between the rows, earthing up of the plants… For these and other works is a lot of mechanisms and machines. Often quite complex, scarce and expensive. Where plot sizes are small and the soil light, many prefer to settle for a commercially available hand-cultivator-Hiller ROC-35A. And here are a couple or alone, characteristic for the latter case, the method “one step forward, half step back”: moving a considerable shock, but with a small (5-10 cm) back.
The proposed microart class DX-02 is built using the experience of Czech and American athletes, as well as materials of the journal “modelist-Konstruktor” about sailing armed with a pyramid scheme. Its design allows to realize the advantages of this scheme over the traditional in terms of the competition in this popular youth class. The yacht is easy to manufacture, and build it could even by a constructor of ship models with little experience.
Today we offer air fighters rather unusual material. It to modelers “mediocre” are not only good examples of several design developments that can be used to practice aerial combat, but based on them the basic principles of the calculation and creation of new machines. We hope that the theoretical part of the material will be even more useful than pure information: it will help not only in understanding the strengths and weaknesses of existing models, but also in the design of bizovac new types.
Among the difficulties which beset the creators of the homemade mini-tractor (MT) at every step, or three, judging by editorial mail, nesereznaya: the complexity of vehicle development is quite reliable and strong engine, compact transmission and rear axle, whose design is largely determined by the mobility of the machine, and its appearance, and maximum ground clearance…
“Hello, dear editors! Write “M” from 1969. Drawing magazine has fulfilled a number of projects. Pleased with them, that is, on all hundred. Particularly pleased with microtracker Amurchonok, has become my reliable assistant. He will plough the ground, and weeding perform, and hilling plants with it — no problem. And required construction works: load, which should drop the mortar (concrete) is thoroughly kneaded. I would like to equip your microtracker potato. The same as in the photo stitch “M-K” 5’89. If you publish the blueprints, then the fall will have time to do everything. To harvest potatoes to carry on their plot for not using old-fashioned shovels, and a modern, mechanized way.
The proposed model glider created based on ideas… not to be used as a construction material balsa and composite materials. The supporting plane of the apparatus — traditional design. Despite the lack of hard cladding nose part of the wing, consoles have sufficient rigidity on twisting. When the geometric proportions corresponding to the best representatives of this class, the model makes a good start with Leer and reliable planning with winds of up to 7-10 m/s. At high accelerations on consoles is not excluded for arbitrary twist, so it is not recommended to install on the glider towing hook with automatic dynamic start.
With the creation of the first combat submarines mankind was in the hands of weapons of great destructive power. Not all naval power and did not immediately appreciated its power and the danger that it represented for shipping. However, until that time, until the sub was technically flawed and the weapons are more defensive than offensive, in the organization of any serious opposition to them by surface ships was not necessary. With this task successfully cope with any armed ship. But it did not last long. Improving submarines have left no doubt that soon they will become a serious enemy surface ships.
Should get hold of your domin part with the land and animals type cows, as memorized from childhood tongue Twister “In the yard — grass, grass — wood” begins sometimes to acquire particular urgency and relevance. In fact, it is a mini-program of preparations for the winter. But for the oven heating is necessary in an average of 8-9 cubic meters of firewood. And cut (the size of the furnace) and pinned! At the mere recollection of this back sometimes whining begins. And then there is worries associated with hay…
