Modern models of air fight as a championship class and “Junior” are in many respects similar in construction and, accordingly, on the concept. They completely satisfy the “fighters” requirements and only differ in the manufacturing technology.
However, despite the perfect scheme, “Junior” subclass sometimes appear unusual decision, the purpose of which, as a rule, are secondary issues. And we offer our “fighters” case: the main goal of our experiments was the creation of ultra-compact models of low mass, designed for engines of limited power. It was assumed that such models will be able to compete in the competitions mid-tier “bouzouki”, equipped with much more powerful (“professional”) engines with comparable maneuverability and speed, however, reduced due to the small mass of medium level of the tension cord. It appears that the experience of working with similar unconventional models and from the individual stages of work results and insights can enrich the theoretical and practical knowledge modelers. In addition, familiarity with the design and technological discoveries and errors generated by creating ultra-compact “bizovac”, will also help in the design models of other classes and types.
First of all, about the tasks that were set in the design of innovative models. As mentioned above, in the first place was required to significantly reduce the weight and wing area that allowed even taking into account the limited capacity of the plant to achieve a high specific speed. It is important to preserve such properties “bizovac”, as their reliability and ease of starting of the engines, and the reliability of their behavior under any atmospheric conditions at any point of the flight hemisphere. The latter requirements are particularly important in the calculation of the operation by pupils not having sufficient experience of piloting cord models.
