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.
AEROBATIC “EXTRA”
If you use as “inflatable fuel tanks cuts rubber catheters are recommended… not to throw away spent cartridges from under aerosol mixtures. The fact that after cutting of the cylinder is possible without damage to remove from the mounts the valve with the housing. And the valve is the ideal adapter for the production of “inflatable” tank. From the larger diameter valve has a shoulder, as if
Many modelers use in training a discrete instrument. Its advantages — low cost and high reliability. But from failures nobody is guaranteed, and discrete hardware problems can lead to jamming of the steering wheel in extreme position. To be able in any case to save the model, just need to modify the drive wheels, causing a few power elements (regardless of their type, whether electromagnets, solenoids, or the centrifugal machine with thrusters on the course or pitch) to work in a single wheel, and separately for half.
In 1988 there was a serious prerequisite to the beginning of work on items for ignition, and primarily on spirals candles glow plugs of internal combustion engines. This was due to the currency problems, which almost completely stopped the flow of imported candles and candle-heads. Also affected by the desire to have a set of coils with different geometrical parameters (for fine-tuning of the engine).
It would seem, what can there be secrets? Many people use on flying models trapezoidal wings — it appears that the process of their manufacture is well established: two templates of the root and end of the profile fixed to the foam blank; two move the cutting filament thermolabile, watching the cutting speed by marking the length of the chords. However, to completely synchronize the movement never fails, which is clearly seen on the “waves” on the surface of the product.
Timemay any flight models are, in fact, consists of two clearly differentiated stages. The first — motor climb. The main objective here is any means for a strictly limited time for a given mass model and power plant to raise timesnow for possible high altitude and to accelerate to maximum speed, allowing for a transitional land use kinetic energy for an extra lift transition point in the planning mode. The most logical way to achieve these requirements is the reduction of aerodynamic drag of the model in take-off configuration.
…Already left behind a crucial period of the war. Vienna, like many Austrian cities, a lot of bitter’ve seen over these difficult years. Destroyed the magnificent palaces and buildings, and striking in its beauty of the bridges in the centre of Vienna there was only one “Imperial”. Yes, and it is now given purely strategic value — now only it connects the two halves of the city between them.The command of Hitler’s troops, based in the Austrian capital, could not know about the approach of Soviet troops, and therefore a lot of attention to the protection of the Imperial bridge. And despite this…
Today we offer young modelers rather unusual development of high-speed cord models apropriada. Novelty design in unusual approach to design. Perhaps this is an approach based on the full (but competent at the same time, taking into account all the important factors) simplification, truly perfect. For good reason, among these designers, there is a widespread saying: “a Difficult decision can find any, and to solve the task a minimum number of simple parts and assemblies — only genius.”
