FLIGHT “ON THE BACK”

FLIGHT

To train novice of group members control cord model aircraft is a difficult task. And in inverted flight, or as it is called, in flight “on the back”— all very complicated. It affects several factors. The first training back to flying starts on polyproteins car, inevitably bound to be very sensitive. Second, the need from normal mode (already a little spent!) almost instantly switch on the back. Perhaps that is why in many circles at this stage and the “wood” mangled a lot, and spent plenty of nerves.

“VIRTULA” FOR ALL

Designing a new racing control line aeromodel, we opted not on some extravagant options, but the proven classic design, well established and fully proven to date. The base design was made by the sports equipment K. Chistov, the champion of Russia. It’s a model we liked, although some decisions of its individual parts and assemblies we have been critical, based on specific conditions and capabilities of our LC too rich equipment of the group.

BOUZOUKI “JUNIOR”

BOUZOUKI Developed and comprehensively tested in our circle, a new model of a subclass of 1.5 cm3 was very successful. For it is characteristic of a good combination of flight stability and high controllability, and wide adjustment of these parameters. The model has become simply indispensable for us, as it successfully functions as a flying trainer beginner certovica, well suited for training of more experienced and fully meets the requirements of boys-sportsmen even in senior competitions. Do note that bouzouki has very good strength characteristics, and in case of serious accidents, the subsequent repair is not a problem. In addition, when the semi-manufacture of such devices in terms of mug is that new development quite technical.

MOTOR WITH… A TABLET

MOTOR WITH... TABLET

Difficult situation with a model micro-motors in our country, and also difficult to explain, but very attractive the desire of some designers and modelers around the world to provide their phones in unconventional engines sometimes lead to very interesting results. The journal “modelist-Konstruktor” tries to acquaint its readers with all the latest developments in this area. Tan, we have repeatedly published materials on perspective, today received universal recognition engines running on liquefied carbon dioxide. Don’t we go around the topic of steam machines, which, however, mainly engaged in ship modelers.

LAND THE BOATS START

LAND BOATS STARTIn the February issue of “Modeller-designer” we met article on the development of a new class of car — unmanaged vetrogonov. Don’t know how reacted to the most interesting suggestion of the authors of that article and the magazine automodeling Federation of sports of Russia, but in our circle it was accepted “on hurrah” — so interesting, affordable and promising was this topic. Work on a new type of machines we started with, that surely will be useful to all, tion interested in constructing vetrogonov — with the development of minimized similarity of the internal rules of the competition and technical constraints applicable to unusual models. On the last point we were limited to only the maximum area of the driving model sailing arms (no more than 25 dm2) and the total dimensions of the machine (prepared by the start condition, it must fit into a cube with sides not more than 1000 mm). Under these constraints, Verkade should be potentially very fast and quite “personable” for forms that will go only to the benefit of the attractiveness and popularity of the competition in the new class. It should be noted that the rough calculations of the maximum potential speed of movement convinced us in the fact that would be very useful, additional development is reduced “oneorzero” type vetrogonov. Here are our suggestions tanovi: sail area limit of 10-15 dm2, and dimensions described Nuba 500-600 mm.

“WOOD” OUT ON THE TRACK

Many modelers, including the tracks, with a sense of nostalgia refer to the “veterans” of the automotive industry. And really, there’s just something incredibly appealing in those completely outdated, historic machines.Those who want a little diversion from the high-speed super-fireballs, dominating in all areas of modelistica capistrani, we offer today to play a very unusual prototype. Thus, despite the seemingly unfavorable ratios and proportions of the machine, to build in its explanation of the trace is not so pointless. The fact that the trace model uses the engine proposed in our journal No. 7, 1994, and having a number of invaluable advantages for copies of this type. Its big torque at low rpm doesn’t do high-speed microcomputers and very dynamic pickup that sometimes is more important than an abstract absolute value of the maximum speed.

RETURN TO BOOMERANG

THE RETURN OF THE BOOMERANGToday the state of technical creativity of pupils, I think we all know — it is deplorable. And even a talented teacher to inspire children is becoming increasingly difficult. One of the reasons the sharp deterioration of the material base of non-school institutions that lead to exclusion from group work sites that require long time to manufacture. It is possible to offer teachers some technical circles (primarily — aircraft modeling) to include in the plan of work of the first year of lessons build exotic aerodynamic projectile like a boomerang. Experience shows that it is quite affordable for newbies. Requires wood and simple tools: a plane, a knife, a rasp and sandpaper. Production time is two or three classes.

MIG-25: THIS AND POLYOPIA

THE MIG-25: THIS AND POLYOPIA-Models, if they are perceived as more or less concrete something resembling a real airplane, was and will be the most popular among “civilized” modelers. Sports car designed for “combat” conditions of hard competition, for all their attractiveness, have become so over-engineered that to take up their construction venture a few units.

Stand Prokopii (they include the greatest part of the products of foreign firms!). Same for Amateur enthusiasts have created many very popular available subclasses. We, unfortunately, now more or less cultivated only a subclass cord polycopy. Yesterday the interest remained at a high level. He had gone among modelers — I hope so — and now. And that’s why we offer our readers a new unexplored direction that conforms to the framework of the existing rules. It is about creating non-traditional polycopy (and there may be a range!). Due to the attractiveness of a General nature such Prokopy and unusual schemes or designs they hope will be able to help bring active attention to a curious subclass.

ELECTRICS – THIS IS PROMISING

Currently in the world wide development and steady recognition of the electrics — RC aircraft with electric motors. In particular, this is due to the creation of and access to medalistki market a wide range of DC motors (with capacity from 25 to 1500 W under its own weight from 60 to 700 grams), Nickel-cadmium batteries of special power series (capacity at low weight without damage to give currents up to 150 A and fast charge currents up to 10 A), as well as special electronic control elements (with small dimensions and mass, switching currents up to 150 A).

GLIDER “CD”

GLIDER This svobodnymi glider — simple, durable, reliable and moderately “volatile” — was created as a training. It was assumed that newcomers in the process of its manufacture and operation will quickly master techniques of the work with the model aircraft materials and will gain the skills to adjust and run the model. However, tests have shown that among its advantages is joined by terrific “volatility” on the level of specialized osakryl models championship.
