If you have a rectifier for charging automobile batteries, a step-down transformer or Latr you will be able to make thermoresin cutting foam. The cutting part is a piece of nichrome wire mounted on a handle of insulating material. Device tool shown in figure 1.THERMORESIN FOAM

Aerobatics cord models is equally good as sport, as a fun hobby. It is not surprising that interest in this type of modeling remains in the world until now, not to say followers of radiopilot. Design cord models evolving, gaining new and new features. Today, we give drawings and a description of the car created in accordance with the latest requirements of flight “fashion”.
New technology for the manufacture of model airplanes, primenyal the modelers of the GDR from the city of Erfurt, the magazine introduces readers to No. 6 in 1977. Today we tell about the well-proven original management system stabilizers models of gliders. I hope that the Soviet model airplanes with interest acquainted with the design of the control mechanism and get it on “weapons” in their practice.
In 1935, in the Reactive section of the CA osoaviahima of the USSR designer A. I. Polar was designed and built experimental rocket. Originally it was called “Osoaviakhim” (R-1). Subsequently, she was given the index R-06. Only manufactured ten of these missiles. After extensive bench and flight tests, during which were worked out the engine and other systems of the missiles, it August 25, 1937 was the official flight tests.
The fact that under natural conditions perform wind and insects at the breeding stations have to do manually by the staff: in the hybridization of tree species they hold dusting brushes or cotton swabs. However, in the morning when this work is most effective, dusting is difficult because of the moisture deposited inside plastic bags isolation of inflorescences. At day same time violated the clean dusting. An ingenious device proposed by a senior researcher of the Central research Institute of forest genetics and breeding V. Iyevlev, will greatly help the scientists.
French fighter-interceptor. In 1967, the firm Dassault, in cooperation with Swiss engineers aircraft factory in Emmen, started work on the modernization of Mirage, known as “Milan” or “kite”. The main feature of the Milan was canards (PGO), which received the unofficial title of “whiskers”, intended to reduce takeoff and landing distances and increased maneuverability in dogfighting. The principle of operation of the PGO was to create pitching moment at low speeds without losing lift and increasing drag.
