Now all over the world modelistica there is a clear trend of withdrawal from the limited rules of the canons of sports equipment. Appear constantly and steadily there are model subclasses: for example, microplane, or, conversely, models of the giants; in several countries, along with other, an official Championships held with the technique created by drawing almost half a century ago.
Will try to keep up with fashion we. If micro – or Maxi-planes require virtually inaccessible for the average Modeler equipment and engines, we work in the style of “retro” we would succeed. And following this direction, as it turns out, can give very interesting results.
We present radiomodulators the machine is designed under the obvious influence of the mass at the time of the expense of building a traditional class of motor vehicles. They were characterized by wings with a double “V”, a rather large shoulders of the horizontal tail and unthinkable from a modern point of view, plus size area of the stabilizers. Also typical was the design and techniques used in the solution of the power circuit.
What is the result of the translation of the “rarity” of the design practices on current conditions radio-controlled technology, can be clearly seen from the drawings. Since the construction of this model is based on the well-known in the mass modeling techniques, it is possible to just require a special explanation.
First of all, about the total aerodynamic scheme. To us it seemed very fertile, as it provides good characteristics of stability and controllability of the corresponding decrease of the angle of the “V” of the wing and the square of the stabilizer. In addition, due to the small spacing according to the height of the axis of the propeller thrust, wing and stabilizer you can count on the small effect of wind and air gusts. RC in the proposed design not only has a low specific loading on bearing surfaces (which is more than important!), but also allows us to achieve extraordinary versatility. The fact that the replacement of the engine hood on the cowling, the power supply apparatus of the engine of the plane is a glider. Flexibility in any application of the model improved by moving to the land of powerful flaps. Lowering them by 5° — 7°, in conditions close to the wind, can be achieved simultaneously using an airscrew of larger diameter and a reduced step, unthinkable though slow and steady flight. The glider in this form on the flight speed and reduce a little behind the championship class models A21 If desired, the flaps can, on the contrary, raise of 2°-4°, thus obtaining more high-speed, insensitive to wind and similar in characteristics to a good pilotagem car.
