Control line racing model class 2.5 cm3 designed and manufactured in a self-similar laboratory of the Palace of pioneers and schoolchildren of the Pervomaisky district of Moscow under the leadership of A. Pyatibratova. Model — winner of national Championships in 1977-1978. Designed for engine KMD-2,5, diameter of wheels 80 mm. With properly adjusted and well firmed engine model of this type at speeds of about 170 km/h Special attention during development was paid to reliability of all units.
Epoxy adhesive, as is known, consists of two components: resin and hardener. Before use, the components are mixed in the ratio of 8 : 1 (by volume). It’s easy, especially when the operation is performed with a sufficiently large amount of resin. But sometimes (especially modelers) need only a few drops of universal glue. Observe in this case, the necessary proportion between resin and hardener is not as easy as it is a very meager number of components necessary to measure at the same time.
Before starting work, carefully examine the drawing and description. Then prepare the tools: small plane, a sharpened knife, pliers or pliers and a jig saw with saws. Materials you will need: a pine rail, a small sheet of tinplate, paper, spool of white thread No. 10, plywood thickness of 1 mm and 3 mm, or micuenta tissue paper or polyester and nitrogly (it may be enamel, “AGO”, supercement, etc.).
In the past year (“M-K” No. 5 of 1979), we introduced our readers to the technology of refinement of microelectromechanical DI-1-3 and EDR-40 to install them on a flying model. The article evoked a wide response among modelers. Yes, otherwise it could not be: after all, nowadays, no one not vysavac>1 doubt the prospects of application of electric motors not just for cord, but for radio controlled models free flight. However, even the best examples of electric motors are still unable to compete with internal combustion engines primarily by power density, its weight IS1 resident students nutrition.
Modern models of air fight as a championship class and “Junior” are in many respects similar in construction and, accordingly, on the concept. They completely satisfy the “fighters” requirements and only differ in the manufacturing technology.
Schematic model of the airframe and the aircraft, as you know, started flying much earlier than their full-size prototypes. Paving the real aircraft’s path in the sky, they are now helping novice modelers to do their first steps in small aircraft. It is a pity that the modern “schematicity” do not differ from those that did even our grandparents: all of the same pine strips, aluminum wire, model aircraft rubber, a little tissue paper, yarn and glue. No new materials, no advanced design and engineering techniques.
About 190 km/h! This is a technical medium speed modern racing model with a powerful engine. Moreover, the maximum operating speed of the model exceeds 170 km/h, this is not the limit. Constantly improving miniature aircraft, athletes strive to further reduce the time of passage of a ten-kilometer distance. Before the Modeler, usually three ways: change the layout scheme, forcing the engine and improved aerodynamics models.
The first time I saw this unusual rocket in 2007 in the championship of Russia in Orel. At the start of class models Ѕ4А my attention was drawn to the flight of the rocket glider container type. From the start of the Protocol we learned the name of its designer — Sasha Scoops from the team of the Krasnodar territory and the flight time is maximum (3 minutes). Just wanted to meet the designer, but in the starting area he appeared and after the second round. But the Protocol after the red number “180” was listed a “0”.
(THE BUILD-POLYOPIA). Building the model-polyopia begin with the manufacture of the fuselage (Fig. 1), the contours of the lateral projection should most accurately reflect the similarity with the copied aircraft. To the fuselage structure demands maximum strength with minimum weight. The greatest difficulty in its manufacture is the reduction in the weight of the tail, which is much longer than the front, So it makes truss.
