Leafing through a binder of “Modeler” in 1975, I noticed an article in the No. 3 car, “rainbow,” built by young technicians from Tbilisi. Enjoy the car, I decided for their children to make such.
Over the past 3 — 4 years in the lists of winners of major Russian competitions in sport flying are increasingly common names “rocket scientists” of the Republic of Karelia. So, on superiority of Russia among older students, the 2008 champion in the class S6A became the student of Petrozavodsk Ilya Drats. And team the victory it celebrated, too, “the rocketeer” Karelia, which was represented by pupils of school № 45. Even in the same class S3A, they were third in the overall standings in fourth place, behind the team of Belgorod and Moscow regions and the Krasnodar territory.
A quick key. Participants NTTM Novokuibyshevsk a freight motor transport enterprise Governance transport control embedded high-speed universal wrench for screwing of pins. Thanks to the use of replaceable liners with Central threaded holes for different diameters of Pins it can be used for screwing studs of any sizes.
The car was built in the days when I realized that the promised “reformers” two cars in exchange for vouchers, not only to me but also most Russians have never get. While we had to work more, and life became worse. On the salary they were paid very irregularly, could not buy a car. But it was necessary to survive. The hope remained only on the earth-mother — only she could help. But the suburban area was far outside the city, and get to it there is nothing.
Designers snowmobiles know that linking directly to the crankshaft of the engine and the propeller is unprofitable: too high engine speed do not allow to use aredigital optimally. To reduce the propeller revolutions Amateur designers use chain gear, ploskostopie belts, banded V-belt transmission. You can meet the most reliable and compact single-stage gear reducers. As a rule, however, they are quite complicated. The most simple design managed to develop one of the enthusiastic Amateur “aerosanitary” from the city of Tchaikovsky, Perm region M. Psarev. On the processability of the mechanism at least tells TC that he “produced” a kind of microseries — was repeated at least five times. Today we introduce you to drawings and manufacturing technology of the gear.
European champion 1979, on models of missiles in the category of S-6-A X. Ignota (Spain). In three rounds it model showed the best result, and the fourth, additional, — 3 min.
Almost all designs drive bikes have a common drawback that reduces their efficiency. This defect is uneconomical expenditure of muscular energy in the change efforts from one foot to the other during the passage of the pedals ‘dead spots’ (the vertical position of the connecting rod). A large part of the muscular effort at this point is directed to the axis of rotation of the pedals and not so much does the useful work, how much increases the wear of the bearings of the carriage. No wonder the cyclists before the withdrawal of the rods from the vertical position. As a result the course begins with partial loss of muscular energy, which causes premature fatigue of the cyclist.
The model is designed to compete in all-around in class F-3-B. Although the airframe is designed for domestic equipment ROOM-2, it can be successfully applied abroad.
If you live not too far from the pond, make our drawings Dinghy, and you will experience all the delights of sailing. But if this ancient engine is not too attract you, the body of the Dinghy can be used as the basis for small motor boats or rowing Dinghy. Materials for it will require only two sheets of plywood and pine slats.
Here come the summer. Where are you going to spend it? If near water, we propose to construct the original floating tool – equiped, that is a Pedalo. He will give you the opportunity to sit in on the morning dawn with a fishing rod, ride on the pond, to explore its most hidden corners.
