In 1946, first flew double an educational-training plane Yak-11, created on the basis of the Yak-3, but with motor air-cooling, ASH-21. Its armament consisted of a synchronous UBS machine gun of 12.7 mm caliber and two 50-kg bombs In 1955 at the request of Czechoslovakia in OKB A. S. Yakovlev developed the under the gun A-12,7. In 1951 appeared the Yak-11 with the nose landing gear and the training Yak-11T with the equipment of a fighter. In Czechoslovakia built a small series of machines under the designation C-11U.The Yak-11

Protection of your house and garden from small rodents, insects relevant today. Various industrial devices “repellents” are on sale, but this same device is able to produce hams with a medium level of training. Unlike many schemes of such devices listed below are quite original. Known schemes are based on the ultrasonic frequency generator (uzch), “loaded” to the piezoelectric capsule. The frequency of these generators can be tailored (adjusted by changing the values of the RC circuit), but it is invariant under the operation of the device, and therefore of the generator. That is, any rodents, insects, birds or animals would not be “programmed” generator uzch (all of these entities are afraid of the discomfort of pulses of a certain frequency), over time, the device ceases to be effective due to rodents or insects exposure.
In 1947 in accordance with the September decision of the government in the aviation experimental design Bureau (OKB-115), headed by A. S. Yakovlev, began development of a heavy landing glider Yak-14 and simultaneously — airborne self-propelled ASU-57. Caterpillar machine was built in the beginning of 1948, and, after a short factory test in April passed on field tests in the research test an armored polygon BT and MV VS (NIIBT Polygon).
Serial production of the new car called ZAZ-969В began in 1966 in Lutsk machine building plant (1967 — Lutsk automobile plant). The car was designed in KB of Zaporozhye automobile building plant, so the name of the machine at first, appeared abbreviation ZAZ.
Recently, in connection with the development of private farms has increased the demand for motor scooter cargo “the Ant”; especially in need of it rural. Only in 1983, will be sold 12 thousand of these machines. For a huge number of our villages is, of course, a little bit. But the motorcycles in the current year is expected to sell nearly half a million. Maybe here lies the reserve of the missing trucks for gardens? Indeed, many Amateur designers rebuild their cars in trucks. Did it D. I. Chernyshev from the city of Kasli of the Chelyabinsk region. He designed from your motorbike tricycle tractor with two rear driving wheels to use on farms, to carry on the truck-semitrailer vegetables and potatoes from the garden.
Soldiers, chess pieces, furniture hardware, original buttons, cufflinks, commemorative badges and medals on the occasion of anniversaries of your friends — only a part of the list of products that you can make yourself, casting. This work is quite even those who have not had a similar experience: it is enough to have imagination, to be neat, and of course, to get simple equipment for home foundry.
