First, the equipment management model. The use of well-proven systems of the type “Pilot”, “Start” or “RUM” is the only (unfortunately!) the opportunity to engage in sectarian terms radio-controlled model aircraft. They are characterized by functionality and a sufficient noise immunity, which can not be said about modern proportional systems available. Of course, digital is no longer considered “fashionable,” and start holders “Supernarrow” or “Navipromo” will look more professional. But… only as long as after a series of accidents model, they will not come to the conclusion that all the same old discrete is better “killer” is proportional to. Incidentally, this feature of proportionally could be used without quotation marks, if to remember, how many aircraft modeling technique, strength, enthusiasm and best creative time is really ditching because of the low reliability of available equipment (including a “Signal” from the GDR). And in favor of the simplest systems says 15-year experience trouble-free operation of radio in our circle.
To improve the reliability of the onboard part of the “Pilot” we’ve completely redesigned the most flawed unit — steering the machine and a separate power receiver (accumulator 7D-01) and actuators (flat battery “earth”).
New servos represent a simple mechanism with a motor and a centrifugal lever actuator, the design of which is well visible in the figure. With the shown sizes and two cargo traction machine from 0.25 to 0.47 kg, its total weight 35 g current consumption enabled machine from 70 to 150 mA. It should be noted that a simple increase in the number of goods it is possible to achieve significant gain traction. As the motor uses a motor from regular rulemaking or DK-5-19. By the way, for odnokolernyh models instead of the receiver “Pilot”, which is not always available to club members, and you can use the receiver equipment of the children’s “Signal”. With the transmitter “Pilot” the system works reliably.
Under a discrete instrument we can recommend two types of models for learning aerobatics. The first type is the simplest, with only a rudder. This technique is shown in figure 1. This model characterize the flat fuselage, in complexity close to the simple wing training airplanes basic force diagram and… good flying qualities. Besides learning the approach and take-off, it fails to execute and figures such as steep descending spiral and corkscrew, of which the model leaves itself.
