In connection with the problem of transporting such a bulky unit, it is recommended to pay attention to rational decision nodes connecting wing panels and tail Assembly. For transportation is not so difficult to remove the main landing gear, then the whole model easily folds into a small convenient “bundle”.

In conclusion — interesting information: according to the proposed drawings were collected by reduced modification of the “eagle” under domestic compression motor KMD-2,5. Power circuit of this model is simplified, and the whole structure was reproduced of the available materials — Linden, pine and 3mm plywood with little use of plywood-“graph paper”. Mini”eagle” was also a good flight characteristics, which enabled him faithfully to serve for two years. The wing span was 1600 mm, so the console was made permanent, although the pair of struts are still preserved. In addition, modified the nose of the fuselage, which eliminated the need to manufacture fiberglass hood.
