Start 30-ies was a time of rapid development of Soviet gliding. The newly constructed plant produced serial training gliders and sent them to all parts of the Soviet Union for gliding schools, stations and groups.
The details of the models are usually made of plastic or metal by machining. However, when they have much better detail molding plastic in a plaster mold. To prepare plastic from acrylic powder AKR-7, zameshennogo on the solvent to a paste-like state. Both of the required components are available in denture sets.
The space is calling the boys. Today almost every student dreams of becoming an astronaut as well as in the distant 30-ies of their peers dreamed of aviation. And like a decade ago, the guys are preparing for the upcoming tournaments. Learn in flying circles a theory to build complex models-copies “Union”, sport rockets, participate in competitions and contests. Only the all-Union competition “the Space” conducted by our magazine, gathers every year hundreds of young connoisseurs of space. The opening of this article a series of articles on rocket modeling, the editors hope that they will be an additional tool for club Directors and their participants.
The name of the athlete rakatomalala Igor Ponomarev, that is, “hearing” and “rocket scientists” and, hopefully, our readers. His technical model development are of genuine interest. For the very same designer search new is the way of athletic perfection, which is especially important for the future of aeronautical engineer (today Igor is a student of Moscow aviation Institute). I guess this is a good example for our young readers.
In the history of the world Cup on aviamodelling sports, this has not happened; 42 athlete speakers with models of gliders, after seven rounds was the maximum number of points — 1260. Many models are specifically prepared for particular weather conditions of Bulgaria — the absence of wind, a weak upward flows. The results of the efforts had an immediate effect. Only the eighth tour has revealed the contenders for first place: canadian modelers Peter and Almut Soviet — Victor chop. The winner was decided in the tenth.
The twin-engine helicopter model. The creation of radio controlled model helicopters is one of the most difficult types of modeling. So complex that at the present time, almost nobody makes such models on their own — specialized firms took over the manufacture of precision parts and assemblies of model helicopters, and the athlete can only collect from a set of parts complete the model and learn how to manage it.
This model can successfully build students 4-5 classes. Best to start with the housings. It can be done chiselling from a block of wood or stacked. If the housing is stacked, panel it with plywood with a thickness of 1 mm or thick cardboard that cover nitrovarnish to not soaked in water. The body parts glue nitrocream.
Simple radio-controlled model aircraft. Do note that this article is designed for those who prefer to build RC models are not alone, and together with two or three associates. For such a complex and expensive Hobbies well together and the work is fun and the purchase of remote control equipment and engine “rainbow 7” is significantly cheaper. By the way, for beginners you can recommend not too expensive equipment, FOCUS 4, FOCUS 6 Korean company Hitek — the first cost is about $185, the second $220.
In the circle model airplanes syut city of INTA has designed an electric starter for starting resinator indoor models. He performed well at the national competition at the indoor model airplanes among schoolchildren of the Komi ASSR.
To limit flight free-flying models are often used machines with wicks. The thread connects the hooks of the fuselage and the stabilizer, locking them in the position required for the flight model. Wick, burning, burn through the thread and releases the stabilizer.
