Strange trail remains for these sleds, rapidly descending from the mountain: the impression is that someone drove on one ski. And only bends on the side added short stroke of the second track. Unusual sports equipment, the construction of which is available to all lovers of breathtaking skiing the steepest slopes, has developed our reader from Magnitogorsk Sergei Chadin. Made of wood, the sleigh combines originality of design and ease of performance. For their manufacturing are required Board or thick plywood and a saw.
MIRACLE SLED
But not to throw out it! And involuntarily thought creeps in to make it a foldable frame. The same as, say, the “Kama”. I reviewed the literature on the subject (including the publication in “M-K” № 3, 1990) and left unsatisfied — too difficult was the recommended design. Had to develop my — more simple. Tried it and now offer to the readers.
A kite is considered to be the grandfather of modern aircraft. This harness motorless soaring leader was the first aircraft in the so long ago, when there was still such thing — aviation. Unfortunately, in the future, kites were replaced by more udachlivey fellow sky — models of gliders and planes.
High speed RC model with electric drive is very popular with modelers-but-wickow and veteran athletes. This to a large extent contribute concise external form guide-registerof prototype that simplifies the design, allows you to make models from a variety of materials and used in the manufacture of a variety of technological methods — depending on experience, availability of certain materials and finished components (engine, onboard equipment and batteries).
The search for new solutions before the next sports season has led our members to very unusual for present-day design. In a subclass of HH-0.2 is now dominated by specialized yacht model. Basically it is a catamaran with a rigid sail-wing or newfangled pyramidal sailing tooling used again in mnogotochechnykh. However and those and others are clearly expressed signs of directions of designing of sports projectiles that have little in common with real yachts. So we tried to go back to the models one-korpusniki, refitting their sailing rigging. The fact that the classical scheme of a cutter with mainsail and staysail in its simplest initially losing performance in connection with birth defects tractive effort of the sails. We have used the so-called stukeley scheme (often referred to as the L-shaped mast). It has much better properties, as it provides the most Agnolo element snap — grotto — optimally and in a wide range of settings of the sails. Do note that designs based on technically sophisticated “bells and whistles” (like rotary wing masts and the like) are generally not considered when creating the model students all that’s out.
