“Silver” the world championship of 1981, the same year the first place among the strongest athletes of the USSR — it is the best feature of the scheme boat built by the master of sports of the international class, the repeated champion and the champion of the USSR and the world by A. Tupikina. A similar model was helped by his colleague Vladimir Dovzhenko to be among the winners of the USSR championship in 1982 and set a new record in class-1.
What boats will not meet the competition. Some amaze with perfection of outline and finish, it seems that it is better not come up, ke will. Others want to pick up and “bring to mind”. But this, though done really skillfully, carefully and conscientiously, initially produces a strange impression. A small case with a nearly rectangular frames, a transverse rail with ridiculously small floats. Whether clumsy trimaran, whether the model is a replica…
There is an element of design, which can be found probably in any moving models. It is the bearing. Often a pair of “shaft — hole” presented in the form of passing through the wall of thin sheet metal or metal wire axis. This couple meet on the microplane in the system control cord the aircraft or in the nose bearing rezinomotornaya, and the boat, built by children’s hands, — the bearing of the prop shaft or hub of the rudder, not to mention the suspension of the microcosm novice automodellista.
Wings, like aviation, has already appeared on the car. At first it was a triangular plane, similar to the fins of fish. The intent of the designers, like “architectural excesses” was to give swiftness appearance. Then, when the car began to compete in speed with the wind on the wings remembered again. Only now they were needed to help the car better “hold” for the road, push him to the ground. The fastest, now not only establish a plane, located above the rear part of the body, but the front of the front wheels to the track pribavlyaetsya small side wings.
Is there any reason to go into specifics slip “school” model, results of which did not even contain the cells in the table of records! If you think about the future, that is. Today we record events are not logged, tomorrow, and the theory of sliding automodelisme not yet developed by anyone, although microcontrolle subject to the General laws of physics.
The first flight of kites I started to build in 1978. Dozens of options are made over four years, helped to define the tests, experiments and subsequent revisions to the best form and arrangements of the wing, to learn the subtleties of the serpent and its behavior in various conditions. All this allowed the “Acrobat” to become a highly maneuverable aircraft with high aerodynamic characteristics. Its design is highly durable. Snakes can fly in any weather, he’s good and confident performs aerobatics in almost any wind (4 to 16 m/s).
What models of gliders was not in the sky above the sports airfields! Short-tailed side by side with these, whose stabilizer it seemed unreasonably far related from the wing, the search of the optimal elongation of the supporting planes of the transformed outline of the airframe in the likeness of a flying ribbon, brachypterous, such aircraft unit. A few years ago, athletes arrived to a common opinion. Although each scheme had its own advantages and disadvantages, experimentally found the best dimensions that satisfy the conditions of soaring in thermals, the flight in a calm atmosphere and in a strong wind. Parameters recognized compromise (wingspan 2000 mm, chord 145-150 mm, shoulder 700— 740 mm), provided smooth, very good results.
Good motorists! Easy turn of the ignition key and the starter turning the crankshaft starts the engine. Of course, we do not encourage modelers to install an electric starter on the motors. We will focus on stationary unit intended to significantly facilitate the launch of the compression and glow model engines. He will provide you great help in training and in competition where the engine run time is extremely limited.
Offer simple, proven in dozens of models of the design of mechanisms to control the stabilizer and rudder for time or rezinomotornaya models. The basis of the first node is duralumin bracket designed for fixing horizontal surface of the empennage on the fuselage, and ensure its deviation on the horizontal axis. The vertical shank of the bracket is wrapped with thread, is inserted into the groove of the fuselage and secured with glue.
To drive in many modern pneumatic machines and tools required compressed air pressure of 3-4 ATM. Is it possible to build a mechanism which effectively would have used a pressure slightly above atmospheric? It turns out that modeling proves it.
