If your radio-controlled or control-line model has a non-removable landing gear or its size does not allow a hand launch, don’t be upset by the lack of a suitable runway nearby. A drag sled will help — it can be used both in winter and in summer. To make such “skis,” you will need a Read more…
When building small-scale sailing ship models, a great deal of work goes into making realistic chain plates. I use a simplified method of imitating these parts and fittings entirely from a single piece of metal. Using a special forming jig makes it possible to achieve good results both in accuracy and in appearance. At a Read more…
As a prototype for this model, a twin-engine boat of the British Air Force was chosen. During World War II, such boats were used to search for and rescue pilots shot down over the sea, and also to perform guard duties. Work on making the model begins with drawing a full-size scale-copy plan. The plan Read more…
The term “autogyro” comes from two Greek words: autos — self, and gyros — rotation. In fact, they define the essence of this aircraft, in which lift is created by an airscrew-rotor that freely rotates under the action of the oncoming airflow, while forward motion is provided by a tractor or pusher propeller.

When preparing a rubber-powered aircraft model for launch, rubber breakage is not uncommon. As a rule, the secured strand, which has a lot of energy, then destroys the propeller and injures the modeler. Recently, many people have been using a protective disc made of plastic, metal, or plywood, which is installed between the rubber motor Read more…
Folk wisdom insistently advises counting chickens in the autumn. Without hesitation, however, let us note: in a period of total shortage that has swept the country, one cannot fail to take care of the timely acquisition of the “source material” — those same live fluffy little balls that are supposed to turn into future broody Read more…
Which exhibition exhibit is the most interesting? Obviously, the one with the most visitors, the one most often aimed at by camera lenses. That exhibit at the 1984 Moscow City Exhibition of Youth Scientific and Technical Creativity was the “Vyatka-1M” walk-behind tractor, built in the auto-design club of the Palace of Pioneers and Schoolchildren named Read more…
In a well-known encyclopedia of the century before last, “Industry and Technology,” in the volume on the “processing of fibrous substances,” which wood also is, it is said that “in work on dividing wood … splitting is of importance.” And further: “a wedge-shaped tool bends apart the parts of the wood being separated; here the Read more…
Compactness, maneuverability, and good traction characteristics are the undoubted advantages of the single-wheel tractor built at the young technicians’ station in the city of Novotroitsk. They were achieved by using a layout unusual for walk-behind tractors — “wheel–motor” — which gives the machine minimal dimensions and a simple transmission. It is no secret that large-diameter Read more…
