SHARPEN DRIVE

HIGH DRIVEWhen using a circular saw with a saw to obtain a smooth cut surface modelers often use so-called “silk” discs, in which the cutting teeth are almost divorced. Sometimes for this purpose use a thin disc cutter. However, to saw wood them is not easy: due to the intense heating the wood ignited. The reason is in incorrect sharpening disk. To overcome this difficulty.

SECRETS FLAPPING FLIGHT

SECRETS OF THE FLAPPING FLIGHT…Model takes off from any position. It was enough to tighten the rubber motor, and two-winged “bird”, vigorously rebounding wings, began the rapid acceleration into the sky. She looked extremely simple. But the plainness of the shape did not prevent her from becoming the prototype of a family of similar vehicles with different engine types and power. They were United on one thing: almost all majority rose steadily skyward. The secret of them, probably, and was in its original simplicity, was originally a perfect Union, mass-inertial and aerodynamic forces…

BILATERAL SLEDGE

The usual children’s sledge with backrest it is possible to carry only rounded chastyami runners forward. However, it is often necessary to transport the child back forward — then his face protected from the wind. A small alteration and it will be possible to implement at any time. You just need to add sacropenia in Read more…

START INTO THE WIND

START WINDMount klementieva in Koktebel — a place special and wonderful in their own way. Fans of soaring rightly consider it the cradle of Soviet gliding, nascent in our country in the distant twenties, and hang gliding, the appearance of which happened before our eyes in the seventies. Today, at the turn of the new decade, the slopes of the legendary mountain was chosen by fans of the new aerial sports — paragliding: so, relay the makers of ultralight aircraft continues.

ITALIAN SUBMARINE “MOSQUITOES”

ITALIAN SUBMARINE “Dwarf” submarine or midget submarines occupy a special place in the underwater shipbuilding. Of them, in fact, grew large submarines with a displacement of tens of thousands of tons with crews of hundreds of people. Virtually all countries after the first small submarines switched to medium and larger submarines. And only two States continued to develop boats and large and small sizes -Italy and Japan.

TRICYCLE, FAMILY

TRICYCLE FAMILYThree weeks it took me to collect parts of old bikes recumbent double the pleasure type. Rapid wedge-shaped profile suggested a name for the new machine — a “Sail”. It turned out onlinefreeroll, easy and strong enough. Low rise creates a purely automotive sense of speed, elongated frame and padded seat well conceal the tremors of the bumps in the road.

R/C TRAINER

R/C TRAINERFirst, the equipment management model. The use of well-proven systems of the type “Pilot”, “Start” or “RUM” is the only (unfortunately!) the opportunity to engage in sectarian terms radio-controlled model aircraft. They are characterized by functionality and a sufficient noise immunity, which can not be said about modern proportional systems available. Of course, digital is no longer considered “fashionable,” and start holders “Supernarrow” or “Navipromo” will look more professional. But… only as long as after a series of accidents model, they will not come to the conclusion that all the same old discrete is better “killer” is proportional to. Incidentally, this feature of proportionally could be used without quotation marks, if to remember, how many aircraft modeling technique, strength, enthusiasm and best creative time is really ditching because of the low reliability of available equipment (including a “Signal” from the GDR). And in favor of the simplest systems says 15-year experience trouble-free operation of radio in our circle.
