To rocketmodeler it is no secret that the easiest way to measure the height of the flight model triangulation method. It is based on the measurement of the angles between line of sight and reference planes. Is the choice of the reference planes and the measured angles is largely determined by the degree of difficulty of the subsequent trigonometric calculations of the height.THE HEIGHT IS FIXED

Zaim standard of six acres, for several years in a row are unique, by definition of neighbors of a vehicle are both upgraded sled, and manual single axle truck. He was convinced at the lowest cost here, indeed, benefit.
Paul A. Deryabkin, snowmobile enthusiast equipment Ivanova from the city, have created more than one snowmobile. His first design, snowmobile-amphibian (photo). successfully tested six years ago. The trail was designed and built trehmernye snowmobile, which also showed good driving performance. But they had a weak side: the lack of stability on sharp turns and when driving on rough terrain. And now created a third option: chetyrehlistnyj snowmobile (figure), which, according to P. A. Deryabkin, was the best.
Isn’t that an elegant car? But this is a self-made design. Produced car craftsman from the town of Sharya, the Kostroma region, Vladimir boaster. “Plumbing specialties do not have any — he writes to edition. — Work as a skydiver-a fireman on the protection of forests. Build your car 4 years”.
For many school model aircraft clubs create room flying models is the only available form of modeling. Judge for yourself: the season of the competition model, as a rule, coincides with summer vacation, and autumn, winter and spring start model is quite difficult weather conditions. At the same time any sports or Assembly hall is a great arena for competition in the class of low-speed models with resi-nomotion. The design of the latter — the process is no less fascinating.
