PROFILE “NACA-6409”. Developed in the early 30-ies in the aerodynamic laboratory of the NAC (USA) for lifting aircraft-biplanes. This profile can be recommended as models of gliders championship class A-2, and RC models of gliders is a small scale.

WHEELBARROW-TRAILER
The new law on compulsory insurance of vehicles in conjunction with the ever increasing prices of gasoline has forced me to give up reliable motorized assistance scooter cargo “the Ant-2M”. I sold it in good hands — in the village.
THE AIRFRAME IS MADE OF FOAM
Offer simple design of gliders developed in the circle of experimental design. syut Kostroma. They are all made mostly of foam, but differ from each other in size, proportions, mass, manufacturing technology wing flight characteristics. Models are recommended for the manufacture of young modelers in the home, in group classes and the technology classes.
VELOPLIVD WITHOUT “DEAD ZONES”
Improving the efficiency of the drive — a problem which concerned not only the designers of the bikes, but the owners of these cars. Since the invention of the Bicycle pedal drive brought, you might say, to perfection. To improve its efficiency without complicating the mechanism is hardly possible.BUILDING A CAR
NOT YET — HIS HANDS To build a car from beginning to end with their hands — a tempting idea, but hardly feasible. The main aggregates should take ready, the serial and only in rare cases to make design changes in accordance with the layout of the car. The main attention should be paid to rational “folding” machines of prefabricated elements, the creation of separate parts and units of chassis and bodies, particularly the body, and in the design of the last is also desirable to use the finished part.
MODERN OF THE OLD…
Machine, about which speech will go, was created as a commercial vehicle, which helps to survive in our difficult time. The car gave me and my son for almost a year. I would like to thank the inspector Gostekhnadzor R. L. Markin. He is also an avid homebrew and a lot of things made with their own hands. And helped us in word and deed.TRACKED WALK-BEHIND
Built by A. Lomakin and tillers, and not absolutely usual — it with a crawler gear: a variant of its execution is best suited for soil in the garden or in the garden. For this purpose, the cultivator is pivotally odnoimennyi the plow. Depth or elevation of the plow is made by the arm movement up and down, the mount which in this case is attenuated and becomes articulated.SNOWTHROWER OF CHAINSAWS
This year we have in the Altai region, snow in autumn, almost a couple of weeks, has dropped quite a lot. Apparently winter is snow, so throw it not to shovel. Okay, that last year gathered a small but reliable snowthrower with the engine from an old chainsaw. In the spring time only experience: he has established himself, in General, good, although not without flaws. Based on the experience of use, summer had made some changes, and now present it to the readers of “Modeller-designer”.PLOWMAN SLOPING FIELDS
Now, as strengthening the material-technical base of agriculture, in all growth, the challenge to improve its efficiency, to improve all quality indicators. This requires… care about how to allocate state funds and material resources were given highest return to better utilization of internal reserves of the collective farms and state farms. And they, these reserves are. Leonid BREZHNEV
MULTI-STAGE STORM HEIGHT
The idea of composite, or multi-stage rocket put forward by K. Tsiolkovsky in 1929. And on may 19, 1938 near Moscow for the first time in the world was launched two-stage rocket designed by I. A. Merkulov, one of the veterans of Gird.
