Unusual “Junior; model class г2А. the description and drawings which were published in “M-K” № 10, 1993, said a surprising impact on the foundations of our reasoning krukowski theorists. Disputes regarding this model were many, and in the end the boys to vychisleniya truth even built exaggerated flying “test layout”, which was legalized in their brain is given in the publication of the First display after “wow guys seems to have decided to take up the manufacture of good oblagorozhenny machine kapatiran engine. But then, it seems, even to his own surprise, he bowed to the idea to develop another idea, which ended the above-mentioned article, In the end we managed to implement an interesting high-speed model-a duck with it and also with the design and g are susceptible of experimental techniques we want to introduce followers aeromodelling class F2А. Perhaps it will help to create not only a “Junior” but also the current championship, very promising “duck”.
On the technical side, design new models, no problems brought. Greatly helped in the journal drawings of the high-speed normal aerodynamic scheme; to a large extent proved to be useful and experience gained in the circle, specializing in cord technique.
However, the main issue arose when determining the alignment of projected “duck”. At first I had to climb on various directories to find at least the principles of aerodynamics focus for the scheme; then, given the traditional high-speed models with stock alignment, you can begin the overall design and the detailed design of nodes. However, (fortunately, at this stage of the work, not later!) managed to find one “hitch”. She’s probably typical in General for all models with wing-band, and therefore it is special conversation.
The fact that the manufacture of the wing of a very large lengthening of the traditional model materials like pine, basswood and balsa to rely on more or less real torsional stiffness in the fuselage remote from the areas is not necessary. Perhaps the situation will change when applying a metal plating or construction of a wing from composite materials, particularly CFRP. However, having no experience of operating speed of this type to undertake a complex and time-consuming technology was pointless (considering the stage of working out of the scheme). When wooden planes wing rishlos to accept the idea that the bearing properties are only privateline areas.
