One of the most important components of the control system with cord model airplane rocking chair that serves as the connecting link between the cord strands and rods for the rudders. Structures of these nodes knows a lot. But, in fact, all of them are divided only into two groups — classic rocking and disk. Both traditional schemes has its own inherent flaws. Thus, the conventional rocking chair in connection with a change in angle relative to the direction of cords in its turn has a variable gear ratio. In addition, this system takes a lot of space in the model, and at large the required control effort, the scope of the rocking becomes so significant that the node weight begins prison the cable that connects the two kordovye threads, thrown through the simple pulley, the diameter of which is limited only by the flexibility of the cable used. The rope on the pulley is not fixed and can therefore drag-and-dropped in the model for the entire length on both sides. One arm cable half-ring is attached to the sealing, which holds one of the levers easy simple politically. If you carefully consider the principle of operation of the new system, it will be clear that the selection of parameters politically fails to provide any parameters of the control system as a whole. It seems that unique rocking chair has no weaknesses.
