Now, when your gain is configured, your tail can still not hold the position exactly. That's because your mechanical gain is not high as necessary. You can fix it by increasing Advanced/Piro Consistency value. Increase it by 5 gradually until the tail will hold. The value should be nearly in all cases between 165 - 200. With higher values the rudder will rotate more constantly and will become sharper. With bigger size helicopter the value is always higher. It depends mostly on the helicopter construction (manufacturer), servo arm and servo type. For Futaba BLS servos or similar, it is needed to increase the value even more (in rare cases to value of 220). You shouldn't set the parameter too high if not necessary (always set only as high as really necessary), otherwise tail oscillation in high extent can occur. You can verify it in a Fast Forward Flight or Pitch Pumps whether the value is too high and you can see any oscillations.
