In the previous issue of “Modeller-designer” followers of aeromodelling was able to gather information about competition rules and guidelines in the new are gaining wider appreciation, direction of technical work — the electrics. I hope that no less favor in entering new theme will bring and a brief description of a few specific successful models that can serve as a kind of “reference point” in the design of this promising technique will become a basis of creation of similar machines. Moreover, the presented model of precisely those classes that are cultivated at present in our country.
Figure 1 shows the basic geometry elektroleta class F5B/7 designed and successfully tested by the author of the previous material — Sergey Sobakin from the city of Dubna in Moscow oblast. The fuselage of the model presented the monocoque shell, moulded from fiberglass, carbon fabric, and SVM on the binder resin brand ED-20. The wing has a standard case design, made mostly of balsa (spars shelves — pine). Structurally, the stabilizer is similar to the wing. Plating of bearing surfaces — adhesive thermoplastic film Solarfilm or RSA-cover.
