What is your Pitouette consistency and Rudder delay?

Hi the rudder delay is 2 and pirouette consistency is 177. My rudder servo is kst bls805x
Some extra infos, my gyro gain is at 70% i try 80% but now changes
Rudder dynamic is 6. Thanks

Any tips please?

Hello,

your tail servo is little bit specific and require different servo arm length.
Can you also let me know what are your current Rudder End-point values?
Changing Rudder servo arm length can help a lot. Your settings looks good. You can set Rudder Delay to 0.

Also make sure that tail slider (if present) is not touching the push rod or even that push rod is not bent there.
Any friction there will make tail performance worse.

Decreasing Gyro gain will help for sure too. Then if needed, you can set Rudder Revomix to 2-3. Revomix shouldn't be needed normally in any case, but can be helpful when using lower Gyro Gain.

Hi the tail end points are both 90

Do you think that i must reduce a bit rudder end point to the side that makes overshooting? So to decrease litle the angle of tail blades?

You can try to make rudder servo arm shorter if possible. Then please readjust rudder end-points.

Ok i will move ball link one hole up but what you think is godd value for end points, 90 -100 is ok?
