The model aircraft easier… Bought a compression motor, collected from reechek Yes nervures wing, planed boards from lime simplest fuselage and fly the model! And this is the simplest aircraft will be in principle the same as control line aerobatic acrobat experienced athlete. Another thing — avtomodelisty… Even the most simple of our “shells” contain chiseled, sanded, milled, hardened, normalized, machined, planed, moulded, blue, chrome, vulcanized etc. details to make that possible only by using modern high-precision equipment. How to organize with the mass boys! Once rescued us, heads of circles, sets of parcel Temp. However, their basis virtually did not leave the club room for creativity.
THE CAR JUNIOR
Today we want to introduce readers passionate about rocket modeling, with interesting design, developed and applied with success in competitions Czechoslovak athlete Joseph Rihoy. In 1983, the model helped him to achieve high results: in the championship of Czechoslovakia, he was a silver medalist, to become the first it was allowed only an unfortunate accident — the parachute didn’t open in the last round, it happened because of moisture on the dome at the last landing in the wet grass. It should be noted that the champion of the competition used the model of such a scheme.
To design a proposed “bouzouki” we came after a careful viewing of many descriptions and schemes of modern models class F2D. Reasoning that the current “fashion” for rough terrain foam machines is justified, decided to retreat and in General repeating the technique of elite athletes. As a result of the sketches turned out to be a promising model, the construction of which is possible with minimum consumption of balsa. We managed to get rid of complex operations on internal relief foam brackets: with fuzzy selection of this material imminent significant leashes and distortion of the profile of the wing ready. Relief parts due to the through-holes allowed to keep a lot of “frame” (and in the end, the flight properties of the model) to the desired level.
In our journal No. 10, 1985 was first told about the devices of a new class of FSR-N and the rules of the competition. Judging by reader’s mail article attracted the attention of many modelers — they opened alluring prospects of design search in the not yet clamped by the technical requirements of the class. And now, when for the first “sighting” of the competition, we can safely predict: the adherents of a new kind of ship modelling will be many. According to authoritative experts, the class FSR-N promises to be one of the most popular in a large family of motor RC.
It is not similar to any of the existing transfer machines. Outside no wheels, caterpillars — not at all friction parts, gland seals. Only the bottom constituting an elastic pad, flexible: can be bent, forming a traveling wave. Wholehog designed and built by the Lipetsk engineer Yu. V. by Arpinum. Projection wanaheda given at different phases of movement. The kinematics of this machine are not very easy to understand. At first glance it seems that, even raised ka solid surface, it does not budge, no matter how much I ran her to the bottom of the wave. In fact it is not.
Today our story is about the original high-speed input developed in the circle of children’s club “Iskatel”. Designed for the most advanced scheme, it contains a number of technical innovations that may be of interest to experienced athletes. Cord hydroplane class A1 favorably known development the lack of scarce or toxic in the materials — balsa, glass and carbon fiber reinforced plastics, which gives the possibility of recommending the model for the building even in the school clubs shipmodelbuilding. The use of standard domestic engine CSTOM KRAS ensures the implementation of fitness standards on the level of a first level up to the candidate master of sports.
Model of champion of the USSR in 1986 in the class S4B V. Lunichkina is the result of work on improvement of the gliders with a flexible slat. Speaking with such devices, the Kazakh sportsman became the winner of many competitions.
“School” model class F2D — further development of the schematic published in “M-K” № 7, 1986 in the article “Record holder… simplicity.” Indigenous improvements of the characteristics of the new device was able to achieve, preserve the unique simplicity of the power unit (which rivals and assigned to our bouzoukis the name “schematic”). This primarily refers to the stability of the start and the behavior of the model in the maneuver on the windward side of the flight hemisphere.
“No, this simply cannot be!” — these or similar words — “the standard reaction” athletes of any rank. And calls it the mention of flight models, three years under construction in our group. When the interlocutors know that this is not about celebarty superoperator, and about the training, though consisting of a dozen pine parts… then the faces can be read only undisguised distrust.
Attract the attention of athletes and spectators time the model is tailless. Most of them presented in the traditional competition “Experiment” in recent years, has a wing to direct the sweep and power system tractor or pusher propeller. However, this scheme has a number of inherent disadvantages. So, with the engine in front of the wing there is a need for additional balancing weight for balancing the tail model, the tail boom has to greatly increase to ensure a sufficient efficiency of the vertical stabilizer. And when using a power plant with pusher propeller there is a significant probability of hitting the hands of the athlete during the spinning propeller when starting Tierney.
