Alexander A. Koksharov distant from the Karelian village of Loukhi — one of the most loyal subscribers of the magazine “modelist-Konstruktor” with 40 years of experience. Since childhood he enthusiastically engaged in the design and manufacture of improvised mechanized equipment. From the pictures that Alexander sent to the editor, only a very small part of what he has created— he has over 50 homemade. Some of them are already dismantled, and others have served the century, part is operated by friends and acquaintances.

Svobodnaya radio control model airplanes, gliders and helicopters is currently being implemented with the help of tiny transmitters that have levers or buttons to apply for the model of the desired commands. All of these devices have nothing to do with the controls of a real aircraft and need to develop specific skills and reactions. This means that the experience of control appears to be useless in the future, say, in the case of the transition has mastered them to the training flights in a glider, and especially on the plane.
To fill the tank of a car in the field — for example, from a barrel or tank of the other vehicle drivers often use a simple hose and the so-called “sucking method”, creating a vacuum mouth, with a hit of petrol. You can avoid trouble if you make a simple mini-pump. For this elastic (flexible) hose with a diameter of 10 — 15mm in length 1 — 1,5 m at a distance of one third the length of the slot and insert the hole with a diameter of 10 mm nozzle length 50 — 70 mm from the same hose, and into it insert the tip of the medical pears (preferably the largest). In the end you will have a trouble free, simple in construction, durable pump (even if he is lying among the tools in the trunk — one piece of his there was nothing to fear).
Readers of radio-controlled model copy of the missile and aircraft interceptor BI-1, the parameters of which correspond to rocket gliders S8F Recall that this flying class combines the model with a mass of 500 g with engines of 40 — 80 N.with. Among the requirements for models of this class — the prohibition of splitting the model into two or more parts (including the engine after the trigger should remain in the container). Besides the active part of the flight (take-off) should be straightforward — ascending spiral and loop invalid. Maximum measuring time of flight of the models in this class is 300 seconds.
Almost all users as a stationary radio stations (including those intended for civil radio on 27 MHz), and automobile radios and 4M AM (amplitude and frequency modulation) are faced with the need for optimal coordination of antenna-feeder devices (hereinafter — AFD) with the transmitter. To increase the range of a portable (wearable) mobile stations are sometimes also connected to respective external antenna, for Example, in the CBS range on an antenna called “5/8” vertical polarization and pin around 1450 mm That is the solution of the mentioned problem is important for all radio Amateurs with an active and effective (long-distance) communications.
On the drawing Board stood out the contours of a completely new fighter, interceptor unprecedented for that time qualities. He will not have to look for enemy bombers — a plane meteoric rise when they enter in the area of its action. A monstrous climb rate will enable an interceptor for a few seconds to attack enemy aircraft, leaving his pilots time maneuvering.
The idea is to make the jigsaw came to me many years ago, but brought it to life much later — when I got someone thrown the faulty sewing machine production Podolsk factory. From the “inside” machines only took the main shaft and the node of the “needle bar”, and other parts dismantled. Cut and the front part of the platform, leaving only a foot under the bar of a G-shaped case. On the sandpaper I ground off all the tides on the lower surface. The bearing at the corners of the drilled hole and through them, inverted the machine was attached to the top of the pedestal bottom. By the way, the Cabinet is also used from the old foot-operated sewing machine. However, to find such a Cabinet should be harder than the machine itself. But it may or may not be made of chipboard with 20 mm thick Top cover closed steel sheet thickness of 1.5 mm (and dural).
Who in the circus like children? Of course, fun and funny clown. And a shaggy red wig, and bright baggy clothes with huge shoes, and tricks — all causes kids (and adults) happy laughter. Such a funny figure of the Croatian magazine “ABC technology” and offers parents do for their children, perhaps with their involvement because if you do not cut, then paint the bright colors of the clothing of a clown any boy.
