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…

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.

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.

WITH THE “BLIZZARD” ON THE VIRGIN SNOW

In a snowmobile “Blizzard”, which I constructed based on many developments, published in “M-K”, merged circuit elements of classic motoart, “amfitriti”, the snow. pneumona and aerolis, that is, almost all the famous trails of mechanisms. However, my vehicle can not be assigned to any of these groups — it’s the combination motorolaring propeller and skis, which is the driver. So I called my snowmobile motoliam. The ka drive them really very similar to the usual walk on the wads, because the driver drives a snowmobile standing up. Experience of its operation showed that the scheme has a number of advantages: high flexibility and good permeability at quite a satisfactory speed — up to 15-25 km h

COMPACT WALK-BEHIND

Homemade cultivator it is desirable to make universal, so it can perform various agricultural operations. However, to create a design that is optimal for any work at the farm, is not easy. So, powerful, heavy duty motor-plow, as a rule, is too broad and clumsy in the aisles, and brisk the tiller can’t beat plowing the dense earth. One solution to this problem is offering our reader from Krasnodar territory Vladimir Yakovlev. Its compact one-wheeled machine will help in the treatment of garden beds, will not damage plants close together and, if necessary, in just 10 minutes will turn into two-wheeled motor-plow.
