Ships rise into the air. From the moment when the English hovercraft (SVP) CR.N1 in July 1959, crossed the 32-mile Strait of Dover (or the better-known us — Pas-de-Calais) between the ports of Calais on the French coast of continental Europe, and Dover on the island Kingdom, its inventor Christopher Cockerell became famous all over the world…
From used electrolytic capacitor K50-6 you can make the switch knob for the radio. It is necessary to free the glass of the capacitor from the electrolyte, but instead pour epoxy glue. After the glue is slightly hardened, it is pressed greased with vaseline the axis of the pen device — up to complete curing. Read more…
If you live not too far from the pond, make our drawings Dinghy, and you will experience all the delights of sailing. But if this ancient engine is not too attract you, the body of the Dinghy can be used as the basis for small motor boats or rowing Dinghy. Materials for it will require only two sheets of plywood and pine slats.
Woolen clothes, carelessly hung to dry after washing, usually elongated, deformed. Do not save even a coat hanger from them, too, there are traces of stretch yarn. To avoid all this will help… tights: they can be skipped inside the woolen garments, as shown in the figure, and hang on the rope.
Here come the summer. Where are you going to spend it? If near water, we propose to construct the original floating tool – equiped, that is a Pedalo. He will give you the opportunity to sit in on the morning dawn with a fishing rod, ride on the pond, to explore its most hidden corners.
In the country, and in the apartment such suspension “kolesnica” will be very convenient for both long and everyday Shoe storage. For its production need only a sheet of plywood and fabric (or leather); the latter are formed pockets, into which is laid the boots, shoes, boots.
Not so long ago in the journal “modelist-Konstruktor” was about the simplest model of a glider made from a conventional packaging corrugated Board material although not aeromodelling, but it is durable, tough and light. By the way, a square meter of corrugated Board with a thickness of 3 mm has a weight of only 400 g, respectively, the density of this material is only 0.13 g/cm3! Experiments have shown that the durable and lightweight corrugated cardboard is well suited for creating flying models. Needed only in the cutting and processing of corrugated Board to consider some of its features and to use a knife-cutter, literally honed to razor sharpness, otherwise cut lines get ragged.
When drilling holes in vertical parts or concrete wall is not so easy to demonstrate the accuracy and not to make a mess. However, this method makes it easy to solve this problem. Take any flat jar with lid — e.g. an empty box from under the Shoe-Polish, — and pressed her to the wall, Read more…
All-around radio controlled model gliders (class F-3-B), which includes three flight exercises, is the youngest species of the competitions of flying models. It is flying on the duration, distance and speed. Place in the competition is determined by the sum of the results of the three exercises shown in the two flight rounds. In competition an athlete may use two models: allowed rearrangement of parts from one to another, however, the weight of the model and the maximum area of bearing surface shall not exceed respectively 5 kg and 150 DM2, and the load on an area of 12 and 75 g/DM2. The rules allow change of the geometry of surfaces in flight using radio control, but the transmission of information from the Board to the pilot is prohibited. The model was run for the guard rails, the movement of the Modeler’s assistant, engaged in towing, shall not exceed 150 m. a climb can be carried out with the help of the engine, for every 1 cm3 working volume of which (but not more than 2 cm3) shall be at least 100 g take-off weight of the model. It allowed the use of additional ballast. The engine operating time is limited to 45 C. To complete the exercise on the duration of the flight, the Modeler is given 8 min of working time at the start. The countdown of flight begins with the uncoupling of a rail (or stop the engine of a motor-glider). Every second in the air is estimated at one point. The maximum number is 360. For a flight over 6 min, the Modeler receives one penalty point for each extra second in the air (down to zero).
On the ridge of the roof of the house I made a weather vane Carlson. The design is very simple to manufacture. The “Carlson” produced from a metal sheet thickness of 2 mm. the Figure and the rod from the rod Ø8 — 10 mm rigidly riveted together. As the rotation unit used the wheel hub of a Bicycle wheel with bearings. Below is rigidly secured large fishing bells (indicated on sketch). The same bell in hand “Carlson”. From the natural vibration during the rotation of the propeller and in the wind all the bells are ringing.
