UNIVERSAL CLASS FЗВ

This unusual model was built by members of syt Berezniki, Perm region. Copy flies perfectly, performs such demonstrations as “flying under the 45° angle” and “pipeline.” Remote speed adjustment of electric motors allows the model to freely come to the “stopover” and after run on the ground again soar into the air so that sometimes it seems — before you the real Il-4. With the design of the copy you are acquainted the head of the aeromodelling circle N. YAKIMOV.
The prototype model has served as a snowmobile amphibian created in 60-ies a group of young professionals under the leadership of the Soviet aircraft designer A. N. Tupolev. This car attracts the severity of the contours (see “M-K” No. 11 of 1978), do not break any complex suspension system of the ski or tubular enclosure of the propeller. And this is a significant advantage Because each protruding element design increases the aerodynamic resistance. It is better to have a bulky, but streamlined body than compressed to the limit, but with the “stork” legs of the undercarriage. In addition, the housing of such a model creates the effect of aerodynamic unloading, manifested even at low speed. Amphibians have relatively small diameter propeller.
