The idea behind the project was never built submarine “Ero” physicist Marie-Davy, to supply its electric motor, it seemed very attractive. Indeed, what could be better than a virtually silent motor which does not require any precious air and not enough fuel. However, as already mentioned, the Professor is too ahead of its time. The full rechargeable battery in the mid-nineteenth century was not, and the boat “on batteries” (battery cells) could be just the gas-guzzling toy. The possible range of such underwater “Electroapparat” was limited to a few kilometers, and to replenish the supply of energy in disposable elements was impossible.

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.
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.
Ski sport in our country every year becomes more and more popular, they are fond of both adults and children.
Imagine readers of the venerable magazine “modelist-Konstruktor” simple in construction and small in size snowmobile, it is available for self-construction. It was designed so that there was no problems with spare parts (for example, there is no single-point lubrication: ball bearings – closed, all sleeves are durable: metallografitovyh and PTFE, and can buy them at any auto shop).
Work on the body EN-route car-copies were never easy. Athletes developed a number of technologies with the use of foams, plastics, paper, cardboard and wikileak made of fiberglass. However, each has any flaws. This can be increased the complexity of the process or poor prochnosti-weight characteristics of the finished product.
