| Richard,
It has been awhile since I had the STD Vigor, but as I recall I believe that the control assembly does not have any bushings. I could be wrong in this case though. You best bet is to disconnect all the links and see how the assembly moves without any resistance from the head or tight links. Then one by one add a link and see if the resistance changes, if it does you probably need to resize the link some. As I remember, my assembly was pretty smooth, and all I did was what I mentioned above.
As far as the servo lagging. I assume it looks visually that the throttle servo is lagging the pitch servo? This is perhaps not the best way to determine if the servo is behind, instead (assuming you engine is reasonably tuned) try doing a vertical climbout and listening to the engine to see if it keeps up with the load or gets bogged down.. Usually, most of these problems can be corrected with working on your TH geomeotry, instead of replacing servos. (I believe Ron Lund had a good aticle on TH geometry on his site) Incidentally, I have found that the larger Servo Wheels (16-18mm hole) work best for maximizing TH geometry on the Vigors. Just my observations.
Hope this helps
