In 1980, the sub-Commission on the rocket modeling of the FAI decided to introduce a new class of raketoplana S8E with a maximum mass up to 300 g engine with a total impulse of 40 n*S. Model of this class, created by Bulgarian athletes participated in the competitions and showed good results. Having the necessary materials, it is easy to make in the flying circle. The engine of rocket with a total impulse of 40 n*works for 10 s. To control the model can be used in compact radio equipment “Craft” or homemade equipment, the mass of which does not exceed 80 g. Usually its the power supply applies a battery capacity of 0.1 Ah and a voltage of 4.8 V.RC ROCKET PLANE

Still, the vast majority of models of submarines with rubber motor class EL-500 (500 mm in length) are built on the same scheme. However, the adopted version with the detachable bow and stern parts of the hull has a number of disadvantages. No matter how carefully manufactured parts, the line connectors on the polished surface of “skin” still stand out, which spoils the appearance polyopia. Students involved in a circle of the second year (namely, they calculated the design of class-EL), not under force independently to build the model without the constant help of the leader of the group.
Every year the competition is less you can see modelers who runs the micro internal combustion manually, without the aid of special starter. Often using mechanical devices, electric starter with battery to use is not very convenient — too heavy batteries, and to recharge them is not always possible in “field conditions”.
Fifty meters distance, but still ten before entering the starting line — the distance the self-propelled sudomodel must pass like a ruler. The slightest error in the adjustment would lead her away from the cherished two-meter finish. Beginners usually try to make my models go straight, bending the rear portion of the keel plate. Imagine how difficult it is to “guess” the right position, and carousing out of place the wind can get back to work pliers. You can easily and quickly get the desired result using one of the simplest devices fixing the turning of the steering wheel.
The rocket plane with Delta wing design is widely known, repeated in dozens of models. However, leading athletes of the country are constantly experimenting, looking for even the long-familiar schemes something new to achieve better results.
In the modeling practice is often necessary for the creation of ellipses of various sizes, with different ratios of semi-axes. There are several ways of constructing such figures. But they are not without drawbacks. Well, I offer reliability and simplicity. However, the required pantograph is a device well-known to widely used. Moreover s requires no change in its design.
The wing of any aircraft should be smooth. It is clear. But how to achieve this? Each athlete solves the problem on its own. Beginner difficult — AA he has no more experience, eyes ve learned to distinguish the slightest variation from the ideal planes, but random twists and curvatures of the wings should not be.
Another interesting application of the foam found young athletes – “fighters” from Omsk Kühtai. For several years, they are on the original foam models with motors are not only successfully fulfill aerobatic tricks, but also spend real dogfights. Suppose there is no such class in the rules of international competition, albeit not as fast and maneuverable lightest “trains” like real sports boytsovkn. But the “pros” they have more than enough. This is an opportunity to train in the gym and outdoors all year round, regardless of the winter cold, and extraordinary ease of use and “start” motors, and simplicity, and consequently, high maintainability models, and minimum flow abundant materials.
