In 1980, the sub-Commission on the rocket modeling of the FAI decided to introduce a new class of raketoplana S8E with a maximum mass up to 300 g engine with a total impulse of 40 n*S. Model of this class, created by Bulgarian athletes participated in the competitions and showed good results. Having the necessary materials, it is easy to make in the flying circle. The engine of rocket with a total impulse of 40 n*works for 10 s. To control the model can be used in compact radio equipment “Craft” or homemade equipment, the mass of which does not exceed 80 g. Usually its the power supply applies a battery capacity of 0.1 Ah and a voltage of 4.8 V.RC ROCKET PLANE

Still, the vast majority of models of submarines with rubber motor class EL-500 (500 mm in length) are built on the same scheme. However, the adopted version with the detachable bow and stern parts of the hull has a number of disadvantages. No matter how carefully manufactured parts, the line connectors on the polished surface of “skin” still stand out, which spoils the appearance polyopia. Students involved in a circle of the second year (namely, they calculated the design of class-EL), not under force independently to build the model without the constant help of the leader of the group.
Regular readers of our magazine are already familiar with the Kaluga Amateur designer V. N. Arkhipov, author of easy and productive tillers (see “M-K” № 6, 1982). However, Valentin Nikolaevich considers that it is not so simple as it may seem: to walk on the plowed land, driving a two-wheel tractor and trailer at the same time, is quite tedious and is not for everyone. That’s why Arkhipov undertook the construction of a mini-tractor with four wheels that “ride” him: to various agricultural work, while not on m itself. The attempt failed, and the light appeared a kind of chair on wheels — tractor “Kaluzhanin-14”. Not so long ago, the author had submitted it to the popular TV show “you can” and received the approval of the competent jury Today at the request of viewers and our readers the journal publishes drawings on which you can build the same “iron horse” helper of your household and garden plots.
Every year the competition is less you can see modelers who runs the micro internal combustion manually, without the aid of special starter. Often using mechanical devices, electric starter with battery to use is not very convenient — too heavy batteries, and to recharge them is not always possible in “field conditions”.
Fifty meters distance, but still ten before entering the starting line — the distance the self-propelled sudomodel must pass like a ruler. The slightest error in the adjustment would lead her away from the cherished two-meter finish. Beginners usually try to make my models go straight, bending the rear portion of the keel plate. Imagine how difficult it is to “guess” the right position, and carousing out of place the wind can get back to work pliers. You can easily and quickly get the desired result using one of the simplest devices fixing the turning of the steering wheel.
She needed the breeder and the owner of the infield, with Nega will go faster the matter at harvest in the student’s production of the brig!Oh and on home mini-farms. Yes and the execution of school programs and research activity — those sections which investigates the impact of various factors on the yield of grain crops, — small, but productive, grind will bring many benefits. It’s lossless, the definition of productivity is the most important final phase of the agricultural season.
In the “M-K” No. 4, 1982, an article was published in which there was a talk about a club for young technology house management № 8 of the city of Vitebsk, about the fun and useful machines that are created by its members. Among the most original devices was mentioned and mechanical sweeping machine MPM-1.
The rocket plane with Delta wing design is widely known, repeated in dozens of models. However, leading athletes of the country are constantly experimenting, looking for even the long-familiar schemes something new to achieve better results.
The design intent of the car-Roadster FOX was born in 2004 from his youthful ideas to build an open sports car with an original appearance to satisfy personal design ambitions. During my school years I was engaged in self-similar sports, a multiple winner of the Championships of Russia. Studied at Yaroslavl Polytechnic University at the Department of internal combustion engines. There’s also graduated from the graduate school. Now I’m chief engineer at a firm which deals with composite materials (fiberglass and carbon fiber worked in high school, being a modeller). Design various non-standard equipment.
