OK got the clutch sorted out

Tail still feels notch and does a the periodic, (not constant) waggle. (waggle waggle, pause, pause, pause, waggle waggle)

No binding anywhere, gain is around 37% AVCS and 55% Normal.

No delay set, limit at 100%

T/R servo seems to be OK, no oddness when tested independantly, the linkage moves smoothly when on the ground and motionless.

Any ideas? I just replaced the entire tail hub/grips/bearings assembly.

Totally at a loss here...
