For a year came into effect new rules on aviation sports, which legalized “school” subclasses of cord aircraft. One of them circuit racing vehicles. Different from “adults” only permit flat fuselages, these models opened the way for many boys in the world-class F2C. For anybody not a secret that, more than in any other class, there still existed an insurmountable barrier for the transition from academic to sports cars. Yes, actually, race training simply did not exist. If you have simplified aerobatic, speed and attack models, racing are required in the beginning to create a championship design. And that was to make the boy who have not yet know which side of the plane take. The classes of racing had to be postponed at times when coming to and experience with different materials, and there will be knowledge in the challenging sport.
A greater number of young athletes to the runaway yacht class P-2. And it is clear. The accessibility and speed of production, opportunities to experiment give the appeal of a “Junior” kind of models. Into is and the quiet romanticism of sailing races in an age when we all were a little tired from the continuous noise of the motors.
Each modeller who builds gliders, you know, what tricks can arrange a gusty wind. However, you can run your paritel ‘ without risk of breaking it’s wings, if you use our suspension system. The Central fuselage of the node we replaced the two on the wing.
The Soviet school of construction of model aircraft air combat has long since gained worldwide recognition. Although it is possible to speak about the attempts to find new opportunities in the design of “boytsovok”, yet in most of the devices for air arts created by the waste, the established pattern: foam forehead and composing the rear of the “flying wing”. Its advantages – ensuring high durability and survivability model, light weight, adaptability to work – and attracting athletes of the highest rank, and young “men”.
First of all look at the model-a benchmark that we have chosen as a “prototype”. This glider was created by the Dutch athletes, having rich experience and traditions in the design of paritala. This model belongs to the most modern developments and has a very high flight performance.
First the model of similar schemes appeared in the all-Union competition in 1982. With them were athletes from Moscow. But at the time of competition for soft raketoplana the type of wing”, Rogallo” they be not could. And further development of “hard” rocket gliders did not have. However, with the introduction in 1989 of a new category (S8 — rocket glider, which have not allowed separation of any elements of the design, including the engine block) this scheme has found a second birth in the category S4 (here design with soft wing is not allowed). In favour of the scheme say and world records set by V. Minakova and S. Ilyin, S. Ilyina at the training camp of the USSR team. The model we present to athletes rocketmodeler.
If in the famous Guinness book of records recorded the simplicity and manufacturability, today we present to your attention a model would be the first contender for such a record. Especially attractive it is for young athletes. This model is a “bouzouki” with the engine working volume of 1.5 cm3. And all that will be needed for the manufacture of its frame, — a little more than five meters pine slats section 3X12 mm. They are easy to saw on the machine “Skillful hands”. The weight of the rails is about 100 G. Hence, with a relatively large wing area (dm2 21) it is easy to achieve a low specific loading and good maneuverability.
Still not having accurate information, will allow the professional micromotors in the school types of the car, we decided a new “sled” design under MDS-1,5 D of production ON Savelovsky “Progress”. If not today, then tomorrow, the race for the result will be a three-band motors in the world is simple cord snowmobile, and on trainings it is possible not to burn preparirovanie and therefore malaisrie MK-17. As you can see, the reasons for the transition to MDS we had.
“Moth” is the name of this sports Dinghy. Thousands of boats ply the waters of the lakes and reservoirs in many countries of the world. Especially popular vessels of this class in Czechoslovakia and the GDR. Sailboats these are not monotypes, that is, do not have strictly defined form. The rules allow while maintaining the basic dimensions of the vessel as modification of its contours and the use of different materials for the housings. One of the constructive options, “the Moth,” we offer our readers. Dimensions sailboat the following: maximum length — 3.35 m, maximum width — 1.6 m, sail area — 8 m2.
We all somehow got used to the fact that in the model aircraft competition “Experiment” most of the participants performs with apparatus of the type “flying wing”. Today, however, experimenting with such models is possible only in the sense to improve sporting results in the institutionalized rules of the subclasses. More serious problems “flying laboratory-wings”, as thoroughly investigated in aerodynamics to solve. The results show these models are much lower than conventional sports.
