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.

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).
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.
Many can make a shift to summer camp? Because it ends so quickly! And no matter how much enthusiasm in the students-smart, funny, summer time beckons them to postpone for a time the tools to escape into the forest to the river or to play football. But there are models that even beginners have time to build just a few classes. And not only build, but also want to experiment with them and compete. These include models of a wheeled yacht. The smallest automodellista it is possible to offer a simple boat. Composing elements in different ways, it is easy to create the most unusual “asphalt sailing”.
Devices leading only pilots, in General, very similar in scheme and design are very different in administration. The reason is simple: everyone builds a microplane “under his hand”, presenting to him the more requirements, the higher the class of the constructor. But even the slightest innovations often lead to a significant change in the flight properties of the model. Therefore, when designing pilotazhki impossible to do without hints of a rich and practical flight experience, solid theoretical knowledge.
None of the types of modeling to the apparatus is not presented at the same time so many conflicting claims as to RC jumper gliders. Imagine that you need to design a machine that combines the properties of high-speed models, gliders-paritala and apparatus created specifically for ustanovlena of records range.
