However, doesn't it then require you to recenter the surface either by trimming or by manually trimming (resetting the linkage on the servo)?
So, aren't you back to square one again?
I just don't see how moving the clevis out will lengthen the throw.
Moving the clevis closer to the hinge line (which is the effect of moving inwards a hole) means that the rudder moves more for a given movement of the pushrod.
It may be true that you have to re-centre the trim, but that doesn't effect the above.
Think of it this way . . moving the clevis, say 2 feet outwards (if there was a hole there!) would obviously reduce the throw of the rudder, it simply describes a larger circle.
