Once upon a time (as many of you will remember) our servos used a square output peg, instead of being fitted with fine splines. There was no electronic neutral adjust, no exponential, no total travel control (volume) and you had to set up your model to fly through the maneuvers with only your ability to "see the angles" needed in the servo's output wheels. Honest! I laugh when I hear people bellyaching about having to set up radios today.
