Tokyo Echo (oz1338)

About this Plan

Tokyo Echo. Radio control power model. Originally single channel, on ailerons only. For .15 to .19 power.

Quote: "During the past ten years I have designed about 100 RC models, almost all of which were single channel planes. To some, it is a source of amazement that anyone could construct this many without losing interest. But, being charmed with the conciseness and simplicity of form in single channel RC, I am working with it continuously in order to obtain the best possible performance.

The Tokyo Echo has been designed for single channel equipment employing only the aileron, instead of the rudder, for control. This departure from normal single channel practice came about when it appeared that aileron-only control seemed to correct many of the faults of rudder-only systems. Although the latter has been used with relative success on high wing, low wing, biplanes, and scale models, it is definitely limited in its scope of control.

In the case of low wing models, it is virtually impossible to obtain adequate control-power even if we made a minimum dihedral of more than ten degrees. Furthermore, in the case of scale models, it is a decisive weakness that single channel RC has been stuck in the mud in its development. On the other hand, multi-channel has made excellent progress, both at home and abroad, with the help of good designs and improved RC equipment. Today, with multi-control, even complexly designed scale models are capable of performing stunts similar to their full-scale counterparts. Therefore, with the idea of enlarging the scope and repertory of single channel, we present an aileron only, low wing design with a small dihedral angle - the Tokyo Echo.

We will say at the outset that this ship is not designed as a first model for beginners. The RC'er with a reasonable degree of single channel experience, however, will find an entirely new challenge and flight experience in this design. As you know, multi aircraft fly smoothly because we can use such controls as elevator and trim in addition to the aileron function. Without these additional controls, the Multi craft would not fly smoothly. It is, therefore, necessary to note the characteristics of aileron-only control, its limitations, and the design measures necessary to compensate for the lack of other control functions..."
