That a kite can be under the control of a pilot to perform almost a full range of aerobatics, very few people know. It should be noted that the modelers individual samples of superslow quite bulky and have a complicated design, which cannot reproduce is not for everyone. We offer our readers a new design “acrobatic” snake simplified scheme. Except for reduced dimensions, it is characterized by the possibility of quick Assembly and disassembly, which is invaluable during transportation.
For clamping the tape of the compact cassette to the tape recorder head is jumped out of the spring with the felt used a foam “cube”. And I do so. But to reduce friction tape on the foam — glued on the “cube” sticky tape (Scotch tape). O. I, Voronezh
Operation of the trike in boreal conditions has a lot of features that should be considered in the design of such specialized aircraft. In particular, taiga del’talet must possess the ability to catch even the small clearing, and when forced landings and at the tops of the trees. The engine of his must differ high reliability, the ability to run effortlessly in the air and on the ground force mi of the pilot. But the staff should have the ability to transform, so that its parts can be had relatively quickly to collect the vehicle, allowing to reach a forced landing to the nearest shelter.
Held in the fall of 1991, sports bilateral meeting of American and Soviet missile-modelers winner in the class S4B was Robert Park, a native of the state of California.

In the competition of young avtomodelistov as the winter sports season and summer now dominates the aviation scheme snowmobiles and cars. Their scheme is already thoroughly known and, seemingly, has already passed all stages of perfection. Studied and worked out every knot simple models, clear design principles from the point of view of simplicity and reliability, stability of motion and speed of the turn.
