Small farm equipment — a great helper in the garden, at the farm. Those who have the area roomier, and opportunities to make difficult a bigger car, opt for microfracture the most energy efficient, versatile and easy to use machine. About your variant of compact four-wheel tractor, called the author of “Zubrenok”, says our reader A. E. Parfenov. Once, flipping through a magazine “modelist-Konstruktor”, read about homemade compact tractor Amurchonok. Liked the idea, and I decided to build my machine for plowing and harvesting in the garden, performing various works in the Hayfield, to facilitate other types of heavy physical labor at the farm. I believe that I did it. The tractor turned maneuverable, powerful enough, looks quite nice and reliable — in two years almost constant use in the harsh Siberian climate had not happened no breakage. At the district exhibition “Technical creativity of youth and schoolchildren of Siberia” in the spring of 1983, my “house of the child” received a high rating and was awarded an honorary diploma.

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.
We can say that in the mid 30-ies of the aircraft wing went down from the sky… ice. It was then that ka “ice birds” high — speed snowmobiles — instead of sails began to put aerodynamic wings are very similar to aircraft. But it took another few decades, and airfoil on the ice in the truest sense of the word was on its feet. Moreover, skaters it just became to put on… coat.
Artificial fertilizers are much more effective if they are applied to the soil dissolved in water. However, to achieve an even distribution but the size of the plot is not easy — because most of the pellets don’t dissolve and drop out as sediment at the bottom of the bucket or watering can.
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.
Every Sunday the gates are opened to the sports section “Buggy ERMZ”. To the factory yard with the characteristic of motorcycle engines crack go dirt buggy. Today exercise. Guys this day is going to the most and everyone wants to try the forces in front of its closest competition, after all, to drive lucky one who has shown the best result of training and worked hard in the creation and preparation of the machine for the contest. The guys mostly 16-20 years, many of them are passionate about technology with a 3-5 class and have an enviable ingenuity. Sports for them is a favorite form of leisure. But soon they will graduate come to the production, army groups, and the technical knowledge and practical sports skills, fitness, purchased in the sports section, will probably come in handy in life. Practice shows that those who engaged in technical sports, proactive and hardworking in the production, they usually say “Jack of all trades”.
Filled with wind-taut sail… This age-old symbol of romance will not leave anyone indifferent. And there is nothing surprising in the fact that the number of sailing enthusiasts every year increases. Today they are much more than you can take the yacht clubs, so work on creating Amateur sailing ships many have no qualified advice.
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.
On the mechanisms used to its movement due to inertia of the rotating imbalances of the journal “modelist-Konstruktor” wrote more than once (see number 5 and 12 for 1975, No. 6 1976, No. 3, 1978). The publication aroused great interest among readers, so we return to this topic. The amazing ability of nutricola, or inertsioidov, as they are called — to move without using wheels, tracks or air screw — continues to captivate enthusiasts-inventors. And although the effectiveness of this type of propulsion is not yet well-known competitor, perhaps one of the most perfect models of nutriton will be a prototype of the future transport. And while we offer to your attention another scheme inertsioidov mover. Its author — kas reader from the city of Ryazan Alexander Mikhailov.
