Aeromodelling is a very beautiful and interesting hobby, but at the same time and time consuming. A long time is a training of improvised drones. Make them too easy. Why should only choose the necessary details!
“TOURIST” IS THE YOUNGER BROTHER OF “VOLYN”
Several minutes before the opening of the amateur car design show of 1966 in Moscow, an unusual microcar with an equally unusual trailer attached rolled up to the starting line. Both the car and the trailer were completely flat: the height of the body did not exceed the diameter of the wheel from the early Read more…
Who as a child cut out of pine bark boat to explore the journey through the ringing in spring Creek? But a boy’s latent desire to build a model ship from the bark repeats the thought of the ancient shipbuilders: it is one of the floating materials. Brilliantly confirmed this Norwegian anthropologist Thor Heyerdahl in 1947.
Children in a hurry. They are in a hurry to become adults. This children’s line for the purpose of education first used, perhaps, to A. S. Makarenko. He loaded the boys a real job and turned irresponsible brats to serious people, proud of themselves and their work.
Snowmobile, manufactured by V. I. Shadrin is not motonarty. The author of the design set out to make winter “Rover” of the Izhevsk motorcycle plant with minimal alteration to improve performance on snow-covered path.
At school, for more than 40 years, engaged in the construction of various mechanisms to facilitate workplace and at home. (In the journal “Inventor and rationalizer” was placed in my article “power saw and pump”, which caused a lot of queries.)
Modelers in different disciplines often have to deal with the problem of determining the speed of rotation of the parts, screws, shafts, and even cassette recorders. That’s what the device advises to use well-known Polish engineer, Janusz Wojciechowski.
PROPOSED RC MODEL GLIDER WITH an ENGINE displacement of 2.5 CM3 model airplanes BUILT by the CZECH VLADIMIR BILY, IT MADE ABOUT 370 FLIGHTS (80 HOURS). THE MODEL IS EQUIPPED WITH DVUHKOMNATNAYA EQUIPMENT.
(The end. Beginning at No. 10, 1973) In the tenth issue of the magazine, readers got acquainted with the General layout of the three-wheeled micro-car, only “Friendship” design Bykovskiy, G. Malinowski and B. Horev. Today we talk about refinement and alterations to the factory components and parts that have been applied in the construction of this interesting machine. Remember that to make their own does not make sense. Even with the appropriate machining equipment it will greatly increase the cost and complicate the work, not to mention the fact that the quality of parts made in primitive conditions, much lower than factory.
DESIGN PRINCIPLES. As you know, every self-propelled model, be it a model airplane, ship or car, has a car, and, therefore, exist for them, the laws of calculation and design can be transferred on the model, taking into account the scale only. This is the first. Secondly, any self-propelled model (like any machine) includes three elements that can be considered mandatory. What kind of elements?
