Schematic model of the airframe and the aircraft, as you know, started flying much earlier than their full-size prototypes. Paving the real aircraft’s path in the sky, they are now helping novice modelers to do their first steps in small aircraft. It is a pity that the modern “schematicity” do not differ from those that did even our grandparents: all of the same pine strips, aluminum wire, model aircraft rubber, a little tissue paper, yarn and glue. No new materials, no advanced design and engineering techniques.

Epoxy adhesive, as is known, consists of two components: resin and hardener. Before use, the components are mixed in the ratio of 8 : 1 (by volume). It’s easy, especially when the operation is performed with a sufficiently large amount of resin. But sometimes (especially modelers) need only a few drops of universal glue. Observe in this case, the necessary proportion between resin and hardener is not as easy as it is a very meager number of components necessary to measure at the same time.
Before starting work, carefully examine the drawing and description. Then prepare the tools: small plane, a sharpened knife, pliers or pliers and a jig saw with saws. Materials you will need: a pine rail, a small sheet of tinplate, paper, spool of white thread No. 10, plywood thickness of 1 mm and 3 mm, or micuenta tissue paper or polyester and nitrogly (it may be enamel, “AGO”, supercement, etc.).
In the past year (“M-K” No. 5 of 1979), we introduced our readers to the technology of refinement of microelectromechanical DI-1-3 and EDR-40 to install them on a flying model. The article evoked a wide response among modelers. Yes, otherwise it could not be: after all, nowadays, no one not vysavac>1 doubt the prospects of application of electric motors not just for cord, but for radio controlled models free flight. However, even the best examples of electric motors are still unable to compete with internal combustion engines primarily by power density, its weight IS1 resident students nutrition.
As soon as the first snow fell, it became clear that the house has no need of such cargo winter vehicle as a sled. Child’s sled for a long time “went” on a well-deserved rest in a pile of scrap metal, and weak they would have to carry the heavy loads.
The voice of the motorcycle or moped is familiar to everyone: a sharp and often as machine-gun fire, the crackle of a motor rips the silence, causing the others to flinch. And harmful effects of the exhausts themselves! With the growing number of these machines increases the degree of poisoning of the atmosphere by exhaust gases. 
Where conventional shovel passes in front of dense soil, this unusual diggers enter the ground like a knife through butter, though the effort inform her foot is almost the same. The secret lies not only in originality of design, but also the new technology of digging remotely resembling a job with a hand drill.
Modern models of air fight as a championship class and “Junior” are in many respects similar in construction and, accordingly, on the concept. They completely satisfy the “fighters” requirements and only differ in the manufacturing technology.
Imagine you are in class technical schools. Class is in session. Lecturer for the Department sets the course, and the students, as expected, sitting at desks and listening attentively. But here ends the theoretical part, and is unusual in that the teacher, instead of inviting listeners to go to the shop or the lab, asking them to stand in the aisles. Then presses the button on the remote, and the tables as the team descends to the level of the seats. Revved the motor… and rows of tables slowly go under the chair! Fifteen minutes — and the room is free for practice sessions.
Description a three-wheeled tandem, published in the journal (№3, 1979), I liked inherent in it the idea to tandem bike of the usual single, without making major changes to the original design. But the proposed version was not very satisfied: still frame of the second bike had undergone the unwanted interference. I wanted to find a way of articulation, that when there is no need to tandem it was possible to restore the bike to original form.
