Training RC model airplane. This publication is for those who have sufficiently mastered the piloting cord model airplanes and thinking about the next step — creating the RC. You can, of course, buy ready-made miniature replica of the aircraft and start its development, however, great pleasure from it is unlikely to get made with your own hands and independently adjusted and test flown the model is not interesting example. And cost is cheaper to buy will have only the remote control equipment Yes servos.

Rocket 8К65 – single-stage, liquid-propellant rocket engine and with load-bearing fuel tanks. As propellants were first used hypergolic in contact with nitric acid (AK-27AND oxidizer) and unsymmetrical dimethylhydrazine (UDMH fuel). Flight control is performed by means of gas-jet rudders.

You will hardly find at least one kid who will refuse to ride on a motorcycle. Here guys we have on ascension syut constructed “Cheburashka”. Guys micromatics this very much: it is small, slow (speed up to 25 km/h); side stroller allows you to roll those taken behind the wheel yet.
A small group of enthusiastic scientists and engineers of the Department of theoretical mechanics of the Kursk Polytechnic Institute, working on the creation of an engine operating without fuel and electricity: they are… replace the flywheel. About these interesting looking we asked to speak to the group leader, doctor of technical Sciences, Professor Nurbay Vladimirovich Gulia, head of the Department of theoretical mechanics Institute.
Karting is the most popular and accessible to young people kind of motor sport. It is also interesting that card — an object of technical creativity. In addition, to gain initial driving skills on them much easier than on cars. You can start even from the age of nine. The simplicity and low cost of raw materials enable schools, Palaces of pioneers and the young technicians ‘ stations to build as many carts as you need for simultaneous teaching of a large group of guys. Also important is the advantage that these sports cars are cheap to operate and do not require storage spacious garages.
Submarines — class ships to naval fleets, is designed for attacking ships and land-based enemy targets from a submerged position. They are divided into missile and torpedo.
Four years is not a long period, but during this time, you can do many interesting things, especially if you work with a twinkle. Four years ago we in the city of Apatity was organized by the club of young technicians. Annually in fourteen circles here, there are about 250 boys and girls. In one of the clubs design and build microvesicle. For more than twenty a variety of structures designed and built metal Cute young technicians.
The competition modelers often possible to observe such picture: running at a relatively high speed model, the participants caught on the fly from the boat. Often this operation leads to breakage. And the battery is wasted after passing the course.
In the manufacture of engine AG-1 used many components from mass-produced engines of domestic production. So, for example, cylinder, cylinder head with studs, a piston finger and piston rings — engine M-106, M — 115, crankshaft, shaft seal and the electronic ignition system with flywheel maggino — VP-150M. Carter taken from the widespread outboard motor “Arrow” (or “ZIF”), Perhaps the use of the cylinder-piston group crankshaft from the engine “IZH-Yupiter”. Additional mechanical treatment of serial parts is as follows.
