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.
The idea of Snowmobiling came to me as soon as I moved to live in the village Belushi Nenets Autonomous district. A large part of the year it’s winter here. And in honor of such a transport which can carry people and cargo on the road. Snowmobiling I decided to make a bike “Voskhod-3”, which was bought in the summer to use it for its intended purpose. Therefore, in the design of the bike changed only suspension.
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.
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.
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”.
