All-around radio controlled model gliders (class F-3-B), which includes three flight exercises, is the youngest species of the competitions of flying models. It is flying on the duration, distance and speed. Place in the competition is determined by the sum of the results of the three exercises shown in the two flight rounds. In competition an athlete may use two models: allowed rearrangement of parts from one to another, however, the weight of the model and the maximum area of bearing surface shall not exceed respectively 5 kg and 150 DM
2, and the load on an area of 12 and 75 g/DM
2. The rules allow change of the geometry of surfaces in flight using radio control, but the transmission of information from the Board to the pilot is prohibited. The model was run for the guard rails, the movement of the Modeler’s assistant, engaged in towing, shall not exceed 150 m. a climb can be carried out with the help of the engine, for every 1 cm
3 working volume of which (but not more than 2 cm
3) shall be at least 100 g take-off weight of the model. It allowed the use of additional ballast. The engine operating time is limited to 45 C. To complete the exercise on the duration of the flight, the Modeler is given 8 min of working time at the start. The countdown of flight begins with the uncoupling of a rail (or stop the engine of a motor-glider). Every second in the air is estimated at one point. The maximum number is 360. For a flight over 6 min, the Modeler receives one penalty point for each extra second in the air (down to zero).
In this competition almost everything was as really big car races: clearly marked and numbered paths, a huge inscription “Start” and “Finish” bright lights, signal lights, gambling, overlapping the voice of the broadcaster the cheers of the fans, overtaking each other swift cars. Still, the racing was unusual. They were not on the racetrack, and in the great hall of one of Omsk schools, and even the largest of launched cars easily fit in the glove box of the usual “Zaporozhets”. As for the racers, most of them have not had time to get out of the pioneer age, and some even from October.
The modelers are well aware, how difficult it is to make a model submarine. A lot of time is spent on installation and electronic equipment, debugging it, setting up steering mechanisms, so that the boat promptly sank and floated. And a disappointment for the team and shipbuilder, when she for some reason goes under the water and no longer appears. Then it is looking for divers and even divers. And not always successfully.
Graceful and swift motorboat is an excellent educational model for aspiring shipbuilders. Work on bliss allows you to develop basic skills that will be required in the manufacture of sports cars of high class. With these boats, if they do, you can arrange competitions; it is only necessary to equip them with outboard electromotorically and to provide a place for mounting a battery from a pocket lantern.
Victor E. Marina from Rostov-on-don from a young age engaged in the construction of models of free flight. In recent time, leading a circle of aircraft modeling on obsut, he became interested in the structures with circular drainer, discreto. However, to achieve good results for a long time could not — flying “plates” were heavy, clumsy, and most annoying, bad flying.
Over the past 3 — 4 years in the lists of winners of major Russian competitions in sport flying are increasingly common names “rocket scientists” of the Republic of Karelia. So, on superiority of Russia among older students, the 2008 champion in the class S6A became the student of Petrozavodsk Ilya Drats. And team the victory it celebrated, too, “the rocketeer” Karelia, which was represented by pupils of school № 45. Even in the same class S3A, they were third in the overall standings in fourth place, behind the team of Belgorod and Moscow regions and the Krasnodar territory.
European champion 1979, on models of missiles in the category of S-6-A X. Ignota (Spain). In three rounds it model showed the best result, and the fourth, additional, — 3 min.
The model is designed to compete in all-around in class F-3-B. Although the airframe is designed for domestic equipment ROOM-2, it can be successfully applied abroad.
Not so long ago in the journal “modelist-Konstruktor” was about the simplest model of a glider made from a conventional packaging corrugated Board material although not aeromodelling, but it is durable, tough and light. By the way, a square meter of corrugated Board with a thickness of 3 mm has a weight of only 400 g, respectively, the density of this material is only 0.13 g/cm3! Experiments have shown that the durable and lightweight corrugated cardboard is well suited for creating flying models. Needed only in the cutting and processing of corrugated Board to consider some of its features and to use a knife-cutter, literally honed to razor sharpness, otherwise cut lines get ragged.
Model missiles Ѕ3А Cup winner S. P. Korolev 2008 Igor Danilov made by well-known scheme called “Chelyabinsk”. Its main feature, distinguishing feature is elongated up to 165 mm tail section. This helped a little to alleviate (about 0.5 g) stern, to shift the center of gravity of the model up.
