wags

Maybe thru one of the rebuilds the rudder linkage was connected to the servo further from it. This would cause more reaction from the gyro than it did before. Try to move the linkage where it is connected to the server closer to it. I think the expresion is shorten the horn. You may want to check travel on the linkage too. Any adjustments to the tail make sure the linkage isn't binding back there. It would be eisier to try to drop the % on the gyro and see if that helps before getting into mechanical stuff.

Make sure all the tail grips are tight!
Tail rotors are tracking.
Boom is straight and rotors spin nice and perpindicular to the main rotors.
Tail shaft is straight.
Tail shaft is not sloppy in the bearing.
Tail slider may have excessive slop in it.

Just a few thoughts.

Good Luck,
Andy
