Before copiers that manufacture aircraft models in the Mel scale, often raises the problem of simulating a power plant with a radial engine. Offers an unusual method based on the use of… conventional steel screws or bolts. First, you need to pick up screws with fine or medium threads, the outside diameter corresponding to the cylinder size of the engine. The screws are trimmed to length and with one edge sharpened needle files tapered tetrahedron (the angle and depends only on the number of cylinders). Then, treating the sharpened surface etched with acid, they oblizyvaet using a soldering iron.
THE MOTOR OUT…NAILS AND SCREWS
Practice starts in the competition boat-“bramahadev” convincing evidence that until today the question of establishing a simple and reliable device for shutdown of main engines after completing the scoring of the race remains open. That is the problem and is dedicated to offer modelers the material.
Even perfectly executed a valid copy of a military ship or self-propelled artillery loses much if its design does not allow to simulate the use of the main weapon of the prototype. But most known simulators does not provide the sound similarities with a shot or hampered their placement.
Hand tools for mechanical cutting of bushes etc. green spaces developed a lot. Including Amateurs samodelki (e.g., see the publication “M-K” № 6, 1985 on universal electrocasnice ESC-1). But in all designs I’ve ever seen, their engines, fitted, which, of course. can impact the cost of the manual tool.
For millennia sail faithfully serve the people, helping them overcome the seas and oceans. But under the onslaught of steam and electricity, he had to concede the monopoly of the single marine propulsion. There was a period when the sails almost disappeared from the water expanses. And still thirst for romance, the desire to test their strength in single combat with the wind and waves in the soul of man died.
Modelers with experience know how difficult it is to produce copies of a sailboat hundreds most likely dead eye, which upholstered in the shrouds of masts, mast, Bram-mast and other elements. The manufacture of such micropetala is a very laborious task due to the complexity of the details and requirements for scale looks, greatly affecting the appearance of microporosity in General.
New built training model aerobatic aircraft surprised everyone, ourselves including. So successful was the combination of spectacular appearance (which is very highly valued by only pilots, as well as time of flight affects the evaluation of judges), the extraordinary simplicity and manufacturability, durability and good flight properties. Therefore, while the new aerobatic machine and is “preseminary” character, we named it “Extra”. It should be noted that the potential flight performance of this model is enough to perform the second sports category.
