Did you know that a lot of aircraft Amateur-built are based on BRO-11M – glider initial training famous Lithuanian aircraft designer B. I. Oscines. Very easy to manufacture and reliable in operation, designed on the basis of classical schools of design of aircraft of the 1930-ies, the glider won the sympathy not only of beginners glider, but Amateur aviators, who saw in the design of the BRO-11 M, and its elements useful for the creation of Amateur gliders and airplanes. While some used the scheme of the airframe as a whole, others copied the design of the wing, a third of its original control system… Word, BRO-11M was a kind of tutorial of novice aviators.
BRO-11M – STEP INTO THE SKY
In your journal repeatedly describes the various designs of devices for removing pressed on the shaft bearings, bushings, pulleys. I propose another option — simple in construction and quite versatile. This puller has become my indispensable assistant: allows you to avoid damage to parts during disassembly, making the work easier.
To the journal is receiving increasing numbers of letters from modelers who make their first steps in the class RC. And, as a rule, one request — publish a description of the glider or plane for the initial training. Increased attention to the units of this complex model aircraft class is clear — the domestic industry began to produce proportional radio control systems, and the achievements of modern radio electronics, in particular the emergence of new circuits, give the opportunity to build a good improvised equipment. Published drawings and a description of the “flying coach”, an interesting series of design solutions that allowed to create a universal multivariate training model. It is made entirely of domestic materials.
When designing the model of the catamaran, calculated under domestic motor KMD-2,5, revealed the need to adjust speed on the radio. Had to carve out two parts aluminum diffuser carb increased length and a rotating door. New diffuser installed instead of the original, so the dimensions of the parts included in the rear wall of the housing, to accurately duplicate the dimensions of the serial. The remaining proportions are random. Note that when performing the planting hole under the flap is necessary to provide a dense enough mutual fit of these two parts. A cross hole in the valve corresponds to the inner diameter of a diffuser in the open position of the ledges at the entrance should not be. The control lever is formed by filing a thin disk, machined integral with the valve.
To make a coffee table for any house master. But when choosing a design most often stop at the traditional scheme: the working Board and four legs. However, such structures are inherent, unfortunately, a serious common drawback of low — stiffness. If you introduce additional crossbar, spacer or stretch marks, will worsen the appearance.
Probably the majority of readers, modelers had to build a model microelectrophoresis. These are good motors, easy to maintain — put it on the car, hooked up the batteries, and you can experience the new design in action. But how well able to use the power of the motor depends on the manufacturing quality of the drive. First and foremost, from its driving member connecting the motor with the mechanism. The slightest imbalance mounted on a gear shaft, the runout of the friction roller or pulley, and the engine will not even crank gear. The origins of the errors most often lie in the landing accuracy of a leading element on the axis of the armature. As a rule, planting the diameters of the parts do not match, and you have to wind on the shaft threads with glue or pull on it cuts the vinyl chloride pipe. It is clear that to talk about alignment in these cases is not necessary.
What processing methods but use the young technology for the manufacture of shells of rocket modeling! The most affordable and waste — vikla CA on the blank paper cylinder, master, “the one receiving a novice can just a few classes. For more complex models, especially copies, it is necessary to use a metal mandrel, fiberglass and epoxy resin. To make such tooling without a lathe, you might need it and when processing fairings models.
