Yes, you can try to decrease Cyclic Gain little bit.

So today I had some time to look into my tail issue.
From day one it gives me a CW piro stop bounce. (Never seen with my VBar.)
(CCW is perfect stop.)

I added some degrees offset by shortening my tail push rod by two full turns.
Must be something like 4 or 5 degrees.
I recalibrated rudder end-points using the software.
(Initial settings with zero offset 150-150.)
New settings file is attached.


I was a bit disappointed, the CW piro stop bounce got worse. :shock:
For the next flight I changed rudder offset to 2 or 3 degrees or so.
(Lengthen push rod with one full turn.)

We will see...

It is important to set the angle to correct side. Your tail slider should go closer to the tail boom.
You can also try to decrease Piro concistency little bit (to 160), it will help too.

Also make sure that the servo horn is at 90° when Subtrim (tuning) is enabled.

Yes, I sure did set the slider closer to the tail boom.
(Compensate rotor torque.)
The servo horn has always been at 90°.

I'll try Piro concistency as well, not really played with that number.
