World of models

Category sport model rockets with a soft wing (S10) is divided into four classes. The most common is the class Ѕ10А. Requirements for models are as follows: maximum total impulse MRD — 2,5 researcher, the starting mass of not less than 18 but not more than 60 g. the Maximum flight time in a round is 180 sec (3 min).

The one who animaetsya room with model airplanes knows what a difficult job the installation of the stretch marks. But they stiffen the easiest transparent planes, and even a small error in the tension lead to distortion of the shape of the wings. The work is delicate, painstaking and long. And if you say that you pereustanovit model (you need to remove the “wood” braces) to bring it into working condition for 2-3 minutes, and even in terms of competition, it will seem unreal to you. However, after reviewing the proposed method, you will see that it is quite possible.

Any of us can certainly, without hesitation, to list a lot of famous planes, cars and ships, inscribed your page in history of development of military and civilian equipment. However, it turns out, the model a scheme could play a significant role. Let not the history of all the equipment, and only one type of technical sport.

The kid from the first start push-rod started the engine, and early test-in. The engine revs, causing the car faster and faster to run on the track. Here are the included machine-cut timing a run of eight laps of the race, which is determined by the speed of the model. One lap to another… But it is! The impression is that someone hung on the rear wheels of the machine and slows down her run. Smooth, easy sound debugged in training “engine” was replaced by strained, jagged roar. Of course, the speed shown “shell” is too small.

In his hands standing on the bridge of a schoolboy elegant model powerboats. The boy winked one eye, as if before the shot. Finally, the wind has abated a little — it is possible to produce a model. Raising astern low backwash water, the boat went to the goal. After fifty meters posed a number of buoys, medium form the gate width of two meters. It is best to get it in them — a rating in the highest. With a frozen heart, waiting for the young athlete how to behave microcode. There is a hit! Even the rising wind and waves did not prevent him to enter into the Central gate.

Do I have to mug for the second year, two seventh graders. Like everyone else, they began with rezinomotornaya contour of the car. In fact, the tenacity with which even unskilled hands, they grind parts, with some passion launched his first microwaveability, it became clear — will of the good guys. Soon they built from kits and simple racing models with internal combustion engines. Gradually became their skillful hands, the children learned to treat different materials, began to feel that is not enough running mikromotorchika and how to troubleshoot to race “whiz” down the left the entire distance along the path of the track.

There is an expression: “the Best is the enemy of good.” It remains true, however not always. Any Modeler familiar with one of the standard domestic compression motors — KMD-2,5. Although it is designed for racing model aircraft, it is successfully used and air “fighters”, only pilots and beginners.

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.
