Conditions signed in 1919 in the Versailles peace Treaty that ended the First world war, the German Navy was devastating. The winners, especially the British, insisted on almost total elimination of the fleet once the second naval power of the world. The Germans were allowed to have mine force, consisting of only twelve destroyers and an equal number of destroyers. The latter can be attributed to this squadron destroyers only conditionally: they all belonged to the pre-war series had weak arms and worn-out mechanisms. It is significant that the newest unit of the fleet of the Weimar Republic was the destroyer S-23, which came into operation six months before the start of the war.

“beats” the beats not only sound, but light pulses. In his scheme includes two transistor of different conductivity. The excitation amplifier is implemented by using positive feedback through the capacitor C1. The pulse repetition frequency — from 40 to 210 per minute — adjust the variable resistor R2. The amplitude — adjusted with resistor R5.
Lightweight, foldable, occupying little space in the house, drawing a table can be made of chipboard or plywood with a thickness of 15-20 mm. Due to the simple design it is easy to do at home, having a hand saw, plane, hammer and some other tool.
The competition rules for models raketoplana prohibit use for take-off surface, creating aerodynamic lift. Flight model can be scored if, at the time the hoist is used only reactive SIPA engine.
Offer paired schematic model made in model aircraft laboratories of the station of young technicians in the city of Nikopol. Structurally, it is a “aviamarch”, consisting of carrier-glider attached to the carrier special locks rezinomotornaya model airplane.
measuring constant voltage value of 100 V. It is produced by the bridge circuit for the transistors T1 and T2. In one diagonal bridge included a measuring device in the other power source.
For twelve years Hobbies quinoloneresistant I developed and produced a number of useful gadgets to the cameras: for filming with the influx, defocusing, with multiplier prisms, feedback survey, obtaining combined titles and many others.
While on vacation in Anapa with a group of tourists during a short-term bus stop near one of the nearby houses saw in the front garden and managed to photograph is my favourite, “a lake with swans”… from tires. Unfortunately, there was no time to get acquainted with the master of the house, or to learn anything about its composition. But a lot (if not all) is clear from the photos.
In the early 70-ies before the Soviet athletes-automodellista was a challenge: dvuhsotmetrovy to exceed the threshold speed in the class of models 2.5 cm3. These days, the speed has mastered many of the leading athletes. A sharp jump occurred in 1973, when during the season a few models exceeded the speed of 220 km/h.
The triumph of the Soviet athlete V. Extencive in the class of models of gliders ended the world championship in 1973. Short nose and a relatively small shoulder are the main design features of the model of a champion. The layout is very different from the standard, which is used by most of our leading modelers.
