What is educational flying model? We are all accustomed to the fact that it is a machine fit only to acquire the initial skills of piloting. In most cases, the training model is built with virtually no requirements for its flight properties. The main thing – to provide the maximum ease of manufacture. Eventually, when the athlete will be accepted for the design of the following models with which it will compete, will be subject to calculations and aerodynamics, and strength of materials, and materials science. But at first – what to suffer, whether… And see the light polulotosa “snags”.
FLIGHT MODEL FOR BEGINNERS
The author and Creator of the Rover, about which speech will go, — Boris Ryzhov — a longtime friend of the readers of our magazine. Photographs of the manufactured machines (crawler and six-wheeled all-terrain vehicles) were published in the journal in 1990 (No. 7). But the desire to create and to make a more perfect vehicle all-terrain since it gets cold. Professional aircraft mechanic and restless Amateur designer, after retirement, continued to build all-terrain vehicles. Why? Yes, until (and, apparently, for a long time) to get to most places in the depths of Siberia, where he lives, Boris Nikolaevich, it is possible only on such machines.

There are still many of Russia’s rivers and lakes that can deliver joy and pleasure to fans of rest on water. But most reservoirs where you can swim in the boat, away from settlements. Leave the boat in places unsafe. So today we offer DIY to see malogabaritnih, simple je the manufacturer of boat-a punt, a description of which was published in the Romanian journal “Tehnium”. Design and technology of its manufacturing on the basis of domestic experience has been slightly modified and augmented. This boat is easy to deliver to the place by car, motorcycle or Bicycle with a small trailer as it weighs less than 67 kg. This vessel can be easily modified for the installation of sails or a small motor.
As you know, in order to drain the automotive engine waste oil, have to drive the car on the rack, or to use the repair pit. However, if the garage has quite a powerful vacuum cleaner, a platform or pit is not required. The vacuum cleaner will allow you to perform this work quickly without spilling while a single drop of dirty work.
Things, household items, furniture break down over time and deteriorate, or gradually wear out and become obsolete. And if in first two cases, all the property owners are trying to save (restore, repair), in other circumstances the majority of things are just thrown away. After all, to give old things a second life, not everyone can, but only people with a creative imagination and skillful hands. About such useful things made by the workman man of old fold out beds of duralumin tubes, and will be discussed.
Among the variety of tillers, microstructural and any other motor vehicles dominate Amateur-built machines, assembled from serial components and assemblies. The selection of a standard motor for most cases it is justified and necessary. But the use of ready-made frames, rear axles, transmissions, gearboxes, clutches almost always makes the homemade is too heavy, bulky and unsightly. A more promising design concept – using the minimum required number of standard units. Such mechanisms, although more laborious to manufacture, but allow the author to realize the most daring design ideas.
I am an active participant of many paragliding events and now flying coach. Thus, we have an opportunity to observe the development of paragliding in Russia. And today I can note a brand new trend in our still young sport. The previous ten years of intensive development and improvement of the domes. Now, however, manufacturers have reached a certain ceiling. Relevant are not only the technical parameters paragliding equipment as its cost and availability for those enthusiasts who cherish the dream to fly in the sky like a bird.
According to the accepted classification today, mini-bikes called microvesicle for the (dimensions allow to store a car in the apartment and transported her in the car).
Plow can be different. In General, the choice of the method of ploughing depends on the size of land holdings and the presence of his master of mechanical means. However, on private land a small area today, the most applicable of various kinds of tillers and winches. The first is convenient because of the productive, economical, agile. The last prevails where not that mini-tractor — tillers not to turn around, that is uncomfortable. But in this case, before the master of the farmstead again there is a choice in what winch to navigate — motorized or electrified.
