World of models

With a slight rustle of the blades of the propeller model took to the air. Passed one circle, two, three. All this is familiar today in many circles of our country guys raise flying model aircraft with electric motors. However, some features of this device are forced intently follow him. Whether unusual for a rechargeable element wing — flaps, or confidence, a kind of reliability of the flight. After all, we are accustomed to the fact that the power of the motor just enough to keep the model in the air.

Looking through the model magazines for the last couple of years, you’ve probably noticed a sharp change in the appearance cord racing model aircraft. They have disappeared, it would seem, absolutely necessary stabilizer. And it’s not just a tribute to another sport fashion. See what kind of patterns are models of the prize-winners of competitions of different ranks, increasingly they are flying wings. Some of the appearance of these devices, resembling a kind of pancake, not like others talking about a more modern and rapid appearance of the model. But form form and racing microplane primarily sports equipment. And from this point of view, a flying wing has many advantages over apparatus of a conventional circuit. What? First, the “tailless” much easier. Typical “representative of the” new school weighs 150 g, while an old over 220 g (without engine). So, significantly reduces the time during which the model accelerates to maximum speed. Yes, after stopping the motor it is hindered by the faster. And this win precious fractions of seconds! Less weight leads to less tension cord control. The pilot is getting easier: even at high speeds the centrifugal force is not so much to strain the hand.

You never thought about the fact that your car racing has a good gyro, and not one? But they are made and put into place your own hands! Their role is carried out by the engine flywheel and gear wheels. In the not-so-small mass and size, the frequency of their rotation is so large that such is not always seen in the “adult” technique.

Why would a self-similar wheels protector? Go RC micromachines on the asphalt, the dirt it knead not necessary. But let’s see what kind of speeds these cars run, what turns them brought to pass!

Develop some automaticity in managing the cord of the model during takeoff and horizontal flight, you can begin to build more complex apparatus. It will help you to learn how to perform all the basics of flight complex: forward and backward loops, turn and slide flight “on the back”. Unfortunately, your first robust model of these figures can not do too heavy reinforced design. Therefore, flight training is based on a different principle: the minimum weight, which gives good flight characteristics at maximum ease, which will allow you to repair the microplane for a few hours and re-enter the track or in the field.

Kind the debut of this model yachts was held in the summer of 1981 at the Moscow city competition modelers. Attention athletes was attracted by the unusual hull shape: broad grancey nose, frames Charpy and a large ratio of width to draught. All this has not previously been used in sailing vessels of this class. The experiment was successful: the model showed excellent driving performance both on passing and on sharp courses.

Many RC modelers dream about. Those who decided to engage in this complicated class of models, usually start with gliders. After all, not everyone is lucky enough to find an experienced teacher who would help to develop not a flying machine, gave the opportunity for several days of joint exercises in the field to acquire the basic skills of piloting superkabuto. And the plane with working rudder and altitude to fly slower and more stable pilot error cause only the loss of a few tens of meters height. Finally, the gliders perfectly fulfilled such an important skill, as the automatic steering rotation regardless of where flies model: for the pilot or away from it.

Conceiving a new microplane, any Modeler primarily decides which engine to put on it. One of the motors power is not enough, others too large, others strongly vibrate during operation. Many disadvantages of single-cylinder engine delivered a two-cylinder of the same displacement. They can be built on a variety of schemes: boxer, Y-shaped, inline. In some cases, if the Modeler is not very important weight, two normal “odnotrahniki” mounted on a common metal frame, connecting the shafts through the gear transmission. This allows to raise efficiency of the propeller by increasing its diameter at low speed.

On the Fifth competition of the European championship miniature rocketmodel class S1B master of sports of the USSR Yury Soldatov brought its designer, the title of champion of Europe 1981. She rose to a height of 1046 metres! Design model developed by a team under the leadership of V. Minakova. Thorough testing of the technology, the reasonableness of the scheme made the aircraft a kind of benchmark: with missiles of this type were made by all members of the Soviet team that won first place in the championship.
