The force that your hand puts on the stickshould be stopped at the stick, not transmitted through the linkages, thecontrol wires, the pulleys, the control horn, or the control surface.If stops are required to pass the inspection, I would like to know thereasoning. My guess (please read: I don't know so I'm guessing) is thatstops located at the control surfaces would provide accurate, possitivemovement control regardless of errors or failures in the control linkage.Also, aren't these planes considered EXPERIMENTAL? When the examiner findssomething that he doesn't like, just tell him its an experiment. (Nostops?.. it's an experiment in your control system. Markings numbers toosmall?.. it's a experiment in stealth. You get the idea.)Robert HainesMurphysboro, Illinois________________________________________________________________________________
