The unusual design of bearing areas — that is the main distinguishing feature of the proposed model glider. Their advantage in ease of manufacture. The absence of cut from the sheet material of the ribs removes one of the major obstacles that usually stand in front of budding aeromodellers. Not once, not twice inexperienced hands of guys spoil tutu scarce mm plywood until it become satisfactory in quality ribs. And propilivanie grooves under the rail spars, stringers and edges too rarely at first. And the quality of the execution of this work depends on the strength, stiffness, and aerodynamic characteristics of the future model.

For years, the rubber motor due to its ease of use and low cost were the main engine modelers. But now, with the abundance of micro-motors boat and car with rubber motor find its ardent supporters, as evidenced, in particular, and editorial mail. Among your questions, dear readers, the most frequent two. So T zavgorodnego from Volgograd, E. Shcherbina from Semipalatinsk, A. Zhdanov of Moscow and other interested in how to calculate the number of turns of the rubber motor to maximize its energy, and what is its maximum energy efficiency.
It is hard to imagine the competition without rocketmodeler launches RC models. It is, along with the competitions models-copies, quite an interesting spectacle, including from a sporting point of view. Of course, impressive for the beauty of the start of the model rocket—glider with a rocket motor and control its flight using radio signals.
If you have a “no” trimmer, it will not break the neighbor… So, to paraphrase a famous song, you can start the story about the problems with manual lawn electromobility. Most of the models imported electrochimprom (from the English word trim — cutting, trimming) is clearly not designed for the Russian kolodong mowing lawns or weeds around fences.
The word “cultivator” has entered our lexicon relatively recently. In principle it is the same tractor only built on the basis of single-axle chassis and designed to actuate a replaceable mounted and trailed agricultural implements, and controlled by the levers behind the operator. In some cases, when the walk-behind articulated to the truck, he becomes the vehicle and the operator does not go and goes.
It would seem, are incompatible. However, wound in a spiral wire can be very useful in the power system. Soft hose connecting the jet engine to the tank, sometimes become a reason for stopping the motor in flight. The root of all evil, it turns out, in that the fuel tube, the bending under the action of centrifugal forces acting on the cord model. You can, of course, apply and a rigid tube, but it is inconvenient because of the difficulties of installation. And so very quickly she “gets used” to inserted into her nipple, starting to pass the fuel through the connection.
The model, which will be discussed, applies to the class of high-speed RC models with electric motor total weight of over 1 kg (F1-E>1kg). According to the world Association of ship modeling and ship modeling sport (NAVIGATION.) it belongs to the class of radio controlled. This is the most numerous class of models denoted by the letter F and a numeric index. For model class F1 (F1-V2,5; F1-V5; F1-V15; F1-E>1kg) the basic requirement to perform a “flight” in minimum time: the winner of the race, which I sudomodel showed the least course time.
The fuselage is laminated entirely of fiberglass, applying resin To Tina-153. The bow compartment to the first frame filled with foam PS-1, which cut the slots for placing the battery and receiver on-Board equipment. Top compartment closed, except the lantern, the cap, providing protection elements of the radio from getting fuel. Servos are installed between the first and second, easier, more frames. Access them from the top when removing the wing from a hatch close to the same cover. Under the wing fairing is made powerful, providing a broad area of attachment of the wing. At the same time the keel is laminated from the aft fuselage. The lantern is made of organic glass with a thickness of 1,5 mm, is in the left side of the oval hole in it glued fiberglass curved pipe to the muffler. Reload the model is carried out using ballast attached under the steering servos.
In No. 6 1981 “M-K” talked about how the members of the design circle agricultural modeling of Chernigov obsut after the tour on the kolkhoz apiary has designed the installation for thermal tick treatment bees. Having built her, the guys undertake the following tasks. In the same collective farm apiary they watched as the beekeeper awl pierces holes in Ulevich the framework under wire to consolidate the honeycombs. The awl is the awl: some plank was cracked, the other hole was tightened and the wire did not protectives through them.
The naturalists and the growers, this set is for you! If before you were with him in the greenhouse a whole bunch of different instruments, but now they are all unified and United in a package that will fit in one hand. Each of the tools can be selected from the expanded fan package and used independently from the rest. What is included in it?
