Since you say that gyro is good and calibrated, make sure the belt tension is correct if the tail is belt driven and not torque tube. If torque tube instead, verify the tail gear is not stripped.

Awaiting the next tornado to fly my kites..

The gyro may not not set correctly or there is another possibility of the rudder servo binding, which may cause this type of problem. Check if the tail rotor pitch slider is perfectly smooth.
