At the world Cup 1978, held in the city of Yambol (Bulgaria) in the class RC raketoplana S-4-D (the maximum mass of 240 g, the total impulse of the propulsion system 10-40 n*s) a convincing victory was won by the American athlete Harold Anglin. In three rounds, his model flew for 5 min in the fourth, additional, 3 min 23 s.
Czechoslovak athlete A. Turnips became the winner of the world championship held in 1978 in Bulgaria. He performed with the model missiles S-6-A. the Distinctive feature of his model — longitudinal connector housings. The model of this design was the only one in competition for the duration of the flight tape.
Flying model aircraft with electric motor is silent and doesn’t poison the atmosphere with exhaust gases. Model spared from the shaking characteristic of internal combustion engines, and, consequently, radio equipment, installed on the models with a motor, works more reliably (especially servos). That’s why recent sales microelectronical new grades immediately attracted the attention of modelers. However, the first samples have revealed some of their weaknesses: the unreliability of the brush mechanism and bearings, lack of ventilation of the armature and ferrite-barievykh magnets. Used for the manufacture of parts of the armature and commutator polystyrene cannot withstand high temperatures (150-170°).
These beautiful and flying planes is very simple. They can do and the guys who have not yet engaged in aircraft modeling. To work they need a dense drawing paper (drawing paper), a few dry and straight straws Ø 2-2,5 mm (grasses, bluegrass, wild oat), silicate office glue. Also needed is a blade for a safety razor, jig saw, ruler and pencil.
Room model pricelet really similar to a Hummingbird. This inhabitant of South America — the smallest of the birds — have much to learn. It can still hang in the air and even fly backwards. Our model is no less maneuverable. The design consists of two polycrylic hinged to each other stabilizer, as well as double-girder fuselage, which is attached to the rod with the rubber motor. He drives the crank mechanism polycrylic. Weave wings and stabilizer — capacitor or a tissue paper.
As the history of aviation, the aircraft can be done from almost any material of the First airplanes he built from bamboo and percale, later, aircraft materials steel Yes spruce pine, them was soon replaced by aluminum and magnesium alloys, but today the high speeds require the use of titanium and high strength steels.
Held in early October 2006 from Baikonur 16th world championship flying the sport has left an indelible impression on its participants and spectators, among whom were those who real launches of missiles and launch vehicles spacecraft. To meet many requests for new sports meeting on the legendary land, the administration of Baikonur organized another celebration of rocketmodeler — held the first Asian championship on rocket-space models But given that the sport is not as popular in Asian countries like in Europe, making it open.
In recent years avtomodelisty closely watching the development of a new direction for technical activities and sports design of high-speed radio controlled model with internal combustion engine. At first they were built by high-class athletes, but now a lot of successful and budding. What are the athletic requirements for these models, and some technical data have model classes f-I and f-II?
This “bouzoukia” developed in the aeromodelling circle regional station of young technicians in the city of Murmansk. Speaking with her at the regional competitions, an eighth-grader Sasha of Beidou became the champion among students. Design feature — a fiberglass sock of the wing, much increasing its survivability.
