Spirit pro tail issue

I have a spirit pro on a agile 7.2. Did a maiden today. And when i pitch up from a hower the tail gets a fast wag/flutter. It is fine on hard stops left and right. What would cause this. Servo is a kds 690tail servo

Hello,
you have to configure Pirouette Consistency and Rudder Delay correctly for your model.
For KDS Agile 7.2, Pirouette Consistency may be around 170. While Rudder Delay can be between 0 - 5.
If it is brushless servo then you should configure Pirouette Consistency even higher and Rudder Delay must be at 0.

I brought rudder delay down to zero.and had pirouette consistency at 185. Was better. I then tried 200 but got worse. So i will try lowering it and hopefully this helps. Would the hard stop affect it at all

I also noticed that when i landed the tail servo slowly kept moving. Blades had stopped spinning and heli was staionery. What would cause this.

Thank you for the info.
You can decrease the value, but not less than 160 for your helicopter.
What is your Stick Deadband? Did you used any trim or subtrim in the flight?

No trim or subtrim. Got trim disabled on the tx.

I tested it today with piro consistency on 160 170 180. But not much difference between them. I will dial up my gyro gain in the tx. And move ball on servo horn in one hole.

I testes it today with piro consistency at 160 and rudder common gain on 1.1 was on 1.4. Big improvement not perfect tho so going to try common gain at 1.0 now. And see how that goes.
