“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 And really, there’s just something incredibly appealing in those completely outdated, historic machines.Those who want a little diversion from the high-speed super-fireballs, dominating in all areas of modelistica capistrani, we offer today to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.

“VIRTULA” EVERY DENT

Elementary simple, ultra-reliable and very good running kachestva distinguished for the attention of young avtomodelistov development. This technique is extremely necessary for the NAC are beginning their career in the technical work malchishek, and for the more experienced, for whom this model may serve not only kachestve simulator, but also as a debugging stand for testing engines and new nodal solutions.

THE GLIDER IS A NEW TYPE

GLIDER

This unusual radio controlled model glider designed in an unconventional scheme: on the one hand, the idea of carrying the fuselage (or “inhabited wing”), the other — hard power structure, constructed as “Rama”. The technology of making a model is the light-tight foam of the rigid elements of the bearing lining. The most loaded zones are enhanced with pine slats. This applies primarily to longeron nodes and edges, as well as composing, not having the foam “cores”, rudders and ailerons with a soft covering.

GIANT FROM ITALY

GIANT OF ITALYRC model airplane, provided in this publication, it is highly unusual for the national school of design. First of all it is established in accordance with more and more of the fashion for Maxi models (it is appropriate to recall that the rules of competitions of the International Federation of air sports is not the first year there is a subclass supermystery models). In addition, its overall design matches popular today modelers orientation on the old стиль1 when models are more like genuine planes 30 years, rather than a pure sports “shells”.

ONCE AGAIN, THE “PISTONE”

ONCE MORE ABOUT THE

Article V. Minakova, “Secrets of the new “piston”, published in the “Modeller-designer”, No. 12 1994, aroused great interest among rocketmodeler. It is available for the first time in a popular form expounded basic principles of development and manufacture of gas-dynamic starting unit (GDU).Today we can offer the attention of randomdevice the research summary starts with DGG athletes from the Chelyabinsk region. This report contains calculations of the dynamics of the acceleration of model rockets weighing 230-290 g engines with a total impulse of 20 to 40 N – S. the Authors first examine the effect of parameters where the speed of descent of the model. And the practical value of this material is that the results of the lengthy calculations are given in easy-to-use form.

TRANSATLANTIK IN MINIATURE

TRANSATLANTICA prototype of the proposed model-polyopia was a unique motor speed the ship Des-triero. Built by Italian club “Costa Smeraldo”, it was intended for a single purpose — to beat the speed record for transatlantic crossing, owned since 1990 no less unique boat Hoverspeed Great Britain. Great work on designing and developing unique vessel was done by the Italians with success: Destriero has passed the way from England to new York in 58 hours 34 minutes and 50 seconds, thus putting a new world record.
