Even some twenty-five years ago, all skis were made of wood, though the best models of individual cubes glued. Naturally, this equipment quickly broke, could not withstand heavy loads. But when there were plastic skis, everything has changed fundamentally, there was a kind of revolution in skiing. Since anyone can without too much trouble to try yourself as a skier, to spend time in the woods, etc. Although, in Indeed, the history of skiing dates back to the distant twenties of the last century, when Robert Lettner attached to the edges of wooden skis metal edges, which allowed them to descend on the slopes. Due to fringing Skiing perfectly cling surface slope, and the athlete was able to control their movements. Today, technology is making skiing incredibly complicated. Thus, the design consists of two parts: Profile tselnoformovannogo top and bottom plates.

This allows the ski to perform all the dynamic functions assigned to them, that such a construction adopted as the basis for most manufacturers. The materials also the most technologically advanced, sometimes even taken from space and aviation industries. These include carbon fiber, Kevlar, quartz fiber, composite materials, aircraft alloys, honeycomb construction, fiberglass. Good skiing can withstand skating on the ice, falling into pits and mounds, sudden changes in speed. At the same time they must have easy and reliable handling in all, even the most extreme situations. So, for better slip in recent years manufacturers have applied to the lower plate special graphite additives, which are tiny particles. This is especially true on long routes without regular lubrication – ski glide just perfect. Thus, each person has access to high-tech product that is able to make an active holiday an unforgettable experience.

Plus cheap shot generates uncontrolled discharge of all. Paintball such limitation is the cost of the ball and the capacity of the tubes in a real shooting – overheating of the barrel. And there are no restrictions, Wali, until the batteries will not sit down (Sachet for 3000 balls weighs less than 1 kg). In airsoft, there are two major caliber weapon 6 and 8mm. Rules adopted by the main Russian Airsoft 6mm caliber. Munitions themselves have different meanings. Balls of adequate quality is not should have the joints and internal asymmetric cavities, in diameter, they differ by a few hundredths of a millimeter.

Lightweight – up to 0.2 oz .- used in the premises; Medium – up to 0.3 oz. – Used in open areas, heavy – up to 0.43 oz .- used for shooting at a distance limit of no long-barreled automatic weapons. There is tracer rounds (very impressive at night, but the unmasking completely), there is ammunition to paint (on the principle of Paintball). But historically, that the most common ammunition for airsoft guns are white and light blue balloons 0,2 gr. Perhaps because of their prices ($ 15-20 for a package of 2-3tys.sht.) And acceptable performance.

Detailed compliance with airsoft weapons until the scheme of assembly-disassembly of its combat prototypes attracts fans of all weapons. The question of calculating the muzzle and the kinetic energy of airsoft, and paintball guns rises constantly. For example, when determining whether the admission of a sample to the game. Not everyone is comfortable with common scale based on the measurement of power weapons on the basis of the initial rate of 0.2 gram of the ball. Again – admission to the game weapons with a caliber of 8 mm forced to introduce a new scale, which is not easy to compare with the primary – because the mass of the ball more. Much easier to impose restrictions on the kinetic or the specific kinetic energy. However, for this we have to operate on formulas that many think is too complicated. Solve the problem, a simple calculator. To use it you need the ms Excel package of ms Office. Download the calculator can be on this link. With regard to the quality of play? Problems are the same. There are experienced players and leaders by nature, and there are mattresses sitting in the rear, which should be kicked to drive forward. Are the same as in any media game management issues. People just riding on the game, of course going to rest, so the integrity running on a platform high enough.
