WORKBENCH by Bill Northrops.


Electronically radio control has pretty much narrowed itself down in the past few years to two basic methods of control. One is the exotic and expensive digital feedback system usually in the form of a two stick four control unit . . . the other is the much simpler less expensive pulse proportional system mostly limited to rudder- only control.
The latter is not as well publicized mostly because it is not adapted to any of the competition categories presently established on a national basis in AMA. This does not mean that single channel is gelling short changed ... it is simply that for the most part single channel is enjoyed by a large segment of modelers who dont give one hoot about competition.
Wed like to try to clear up one misconception about sc that probably causes many modelers to look down their noses at it. Sc is not really radio control as we most commonly know it today. It really relates back to the early days of radio control when the models used were basically free flight and a rudder controlling device was employed to interrupt the models otherwise natural flight as determined by preset trim adjustments. In those days the successful RC flier carefully trimmed his plane for free flying and then lacked on the radio as a means of keeping the plane in the same county maybe even the same field. If the radio happened not to work the plane just kept on flying much as it did before the owner stuffed it full of wires tubes relays batteries and other junk.
As radio systems improved and became capable of more control the airplanes became less and less inherently stable in many cases by necessity since the radio could now do what the plane used to have to do by itself . . . maintain smooth and steady flight. If the plane is too stable by itself it becomes difficult for the radio control to overcome the stability in order to perform certain maneuvers.
OK so now back to single channel. Here it is still a radio control system but now under the new concept of let the radio do it the uninformed modeler figures that if its a radio itll control his airplane . . period . . exclamation point. And so he saddles the single channel to some bomb that probably needs all the help it can get from at least a 4 channel proportional system and expects it to do the job ... . No way
