According to the rules of the competition model rocket must use only during takeoff the thrust of a jet engine, and the descent of the lifting force of the aerodynamic surface. For performance of requirements it is desirable that during takeoff the shape of the model was close to the missile, that is, would have a minimum lateral area. This requirement is most fully correspond to the model raketoplana with variable wing geometry. Very promising, in particular, the use of all-moving front wing, which at launch is located along the fuselage and therefore has little effect on flight, and the transition planning rotated across, providing the necessary redistribution of aerodynamic forces.
THE ROCKET PLANE “THE DUCK”
In the third issue of our journal in 1968 published a description of the design of snake-gibralta for water skiers, created by the pioneer of this sport in the USSR — Alexander Casein. Over the years the enthusiasts of technical creativity — IV first skiers — produced a large number of these aircraft. Flying snake-gibralta for the boat or car for many has become a favorite form of recreation. There had also been a successful winter flying in the mountains. Muscovite M. Gokhberg, master of sports of water skiing, winter 1973/74 year was flying on a kite, accelerating on the ski slopes in the area Terskol in the Caucasus.
Svobodnaya “out of fashion”. Especially young modelers. What is the reason? Perhaps, in the length and lack of entertainment competition? And maybe the disadvantages of the method of manufacture of models of this type? In fact, if in the first year of studies in the clubs, build conceptual models, the second — planned complex fuselage model. That’s why the need to create a new expense of building a traditional class of models for modelers working in the groups the second year, is dictated by life itself.
Say, in the Urals during the difficult years of chaos after the civil war an artificer built a car where everything was wooden, even the engine. However, if the wizard so the echo legendary as Leskov’s Levsha, here the use of wood instead of metal in the most important nodes in modern machinery: rolling mills, tractors, cranes, harvesters — not a legend, but a reality of our days.
The idea is to make two-cylinder engine came to us with the son, that is, from want. In times of General scarcity in the economy was necessary for some vehicles to have the house and farmstead to provide those without something to exist person in the Russian hinterland is simply impossible. This is the wood, hay, building materials, which had to bring. Plowing and treatment of the infield in the required quantities without the technology, too, was unbearable.
The article “Acupuncture for metal”, published in the journal “modelist-Konstruktor” No. 2, 1974, provoked numerous responses, not only individual readers, but also many businesses and organizations. Editorial Board, ENEA USSR and VNIIST continue to receive letters and inquiries on the subject.

SMALL SPOOL, BUT PRECIOUS!
A simple design of the airframe suggested that the German model airplanes G. Jung and C. Rosa (Fig. 1). The model has good performance and can be built athletes having small practical experience.
Ask any kid, building the first schematic model of what he wants Almost certainly he will answer — about copy. And it is clear. It’s no wonder it is believed that the replica model is one of the most interesting and complex classes of aircraft modeling. Order copies, model airplanes acquainted with the technical achievements of aviation, possess the perfect use of the tool.
