In three rounds, his model flew for 5 min in the fourth, additional, 3 min 23 s.
Spearfishing in waters with complex bottom relief and limited transparency of water has its own characteristics: no time to restore the gun, nowhere to maneuver. Rifle, currently available in the sale, for such conditions uncomfortable. Which is preferable underwater guns. Of the known types of such weapons is most suitable — capsule. Their main advantage is that when fired the harpoon at the impulse of several hundred kilograms, in contrast to the guns of other systems where the force on the harpoon does not exceed tens of kilograms. Accordingly vary the speed of the harpoon. The advantages of cap and ball pistols can be attributed to the ease of loading.

Flying model aircraft with electric motor is silent and doesn’t poison the atmosphere with exhaust gases. Model spared from the shaking characteristic of internal combustion engines, and, consequently, radio equipment, installed on the models with a motor, works more reliably (especially servos). That’s why recent sales microelectronical new grades immediately attracted the attention of modelers. However, the first samples have revealed some of their weaknesses: the unreliability of the brush mechanism and bearings, lack of ventilation of the armature and ferrite-barievykh magnets. Used for the manufacture of parts of the armature and commutator polystyrene cannot withstand high temperatures (150-170°).
