Motorists know that if a car a long time not to use the battery terminals to prevent oxidation must be removed, and the open contact of the battery terminals to isolate. The easiest way — the usual plastic bottle caps. On the negative pin tightly put on the cap from a half-liter bottle, and on the positive — from 0.75-liter. Conclusions closed by such caps are not oxidized, and the battery is protected from accidental short circuits.
DROWN TO CONNECT
If the fastening of wooden parts and the screw will be less than their thickness, drill the recess with a diameter of under his hat, and the screw will “pull” to the second part, securely connecting them. Remains to putty the hole, “hidden” screw.
To make this model forces students 4-6 grades, first starting modeling. The first detail which you will need when building Navoiy 6. It is made of the housing 4 missiles and cap-cone 1. The last carved out of tree diameter casing.
Old but wise proverb says: “Bread is a head”. Here are only stocking it in store is hopeless. So very quickly it hardens and dries, and then becomes moldy and unfit for consumption. And as you know, especially the delicious fresh bread. But people still have not found a way its long-term storage without loss of taste—except that rusk. But the last mistress use rather of despair.
Increasingly, we receive letters from readers describing flying models, which instead of internal combustion engines operate motors of different systems. This is quite natural and timely: judging by many indications, the electrification of aircraft modeling – in sight. No wonder the first successful examples of flying models are available in the “toy” version of some foreign model aircraft firms. Among them are low-cost models, capable of conducting free uncontrollable flight duration of 1-3 minutes, Cordoba for the different types of food on the wire and even radio-controlled model of the coast, including the piloting. The duration of the last flight without recharging has managed to bring up to 10-15 minutes. However, the electric power is still inferior to compression and heat rating.
Novice automodellista propose a simple model with a body made of thin stiff cardboard. Manufacture the body you need to start with drawing and cutting with the side walls of the pattern No. 1. To get the contours right and left walls, the pattern upside down. After cutting the parts beaten out from the inner side with a hammer, giving them a slightly curved profile. Longitudinal breaklines make incisions on half the thickness of the cardboard on the outside and the inside — on the dotted line.
The main aircraft for training pilots in the great Patriotic war was the U-2 (Po-2) and produce the resource UTI-4. Double export fighter I-7B, Yak-9 and La-7UTI in flight schools were a rarity — they didn’t even spare regiments, and training pilots on them was expensive. In this regard, in the war years in OKB-115, led by C. A. Yakovlev, began the future development of the Yak-18, which replaced the At-2 as a “school” pilots. However, future air fighters needed the aircraft for training their shooting at air targets and bombing.
