Quoting Tommy Terry <[EMAIL PROTECTED]>: > Does anyone know the amount of slack that is "tolerable" in the center > control section? 93929 has about 1/8 inch movement of the aileron bell > crank before the rudder bell crank moves. = The correct test (according to SB something-or-other) is to lock the yokes firmly (or the opposite aileron). Then, assuming that the aileron counterweights have been removed, I think you are allowed 3/16" free-play at the aileron trailing edge. Not much. My experience is that it feels much better with less. And that the culprit is usually the bell-crank in the wing root that is the last thing before the aileron push-rod. It gets play in the bearing. I've found that, if they're even 3/16" loose, I get a sort of oscillation in the wings at about 121MPH IAS. Not encouraging. Can you say 'flutter?' Take it down to 'real tight' and it goes away. They seem to last about 300 hours. Easy replacement.
