Universal control line model aircraft. The design “Teardrop” models for air combat — have occurred in several stages. In fact, immediately, in one step to create obedient to the pilot model was not possible, believe me, anybody. As a rule, first designed and built a simplified model, which practiced its concept, geometric parameters, the controllability and stability of the flight. Further, according to the results of test flights made necessary modifications, and then creates a second version of the model in which the basis is all the best from the first. Sometimes the model is good, but often for the second stage follows the third…

Scoop for garbage collection — it would seem that can be easier. But no, in this elementary product their problems. In stores sold plastic shovels (one-piece) and with a metal bucket and wooden handle. And those and others to be unreliable: break on the bridge at the junction of the handle with the vertical rear wall of the bucket. Is inadvertently pressed a little harder to scoop semi — Yves plastic crack is formed, and a metal jumper — plastic deformation. Over time, the defects accumulate, and the result is failure.
When the designers of trucks “taught” them of the body independently, without other auxiliary mechanisms, to pour onto the ground or into a special hopper delivered to the site loads, some cars received a new name — dump. With the introduction of devices created by the innovators and A. A. Barlevy years ad from SPKTB “Avtospetsoborudovanie”, fвтомобили will be able to do without any additional lifting devices to raise the body intended for transportation of cargo. And may appear by analogy with truck specific name — samagro.
The production model better to start with the most labor-intensive details — wing. Here it is rectangular and consists of 14 ribs, two spars, the front and rear edges and two endings. Take the time to manufacture for the first training model two or three wings, because during training it is possible a failed emergency landing.
From a young age was fond of technology and like most boys, dreamed of being a pilot. But, like many, for a number of reasons they did not, and acquired the specialty of a mechanic. However, it is also a favorite field for me is not extinguished the desire to somehow get closer to aviation…
