VBAR - Tail rotor problems with mini VBAR
I have a lot of experience with Align GX3, but this is my first VBAR and I have these two problems.

1 - Oscillation of the tail - the same helicopter, doesn't do it with 3GX.
2 – I can’t change the gyro function from “Hold” to “Normal” from the Tx (Spektrum DX18).

These are my best vbar settings on Align 450 DFC.
Main rotor: Style 100, Agility 80, Gyro gain 55.
Tail Rotor: Gyro speed 90, Gyro gain 70.
Tail rotor: Band 2, Acceleration 55, Gain P 40, Gain I 40,
Stop Gain A 30, Stop Gain B 30, Expo 50%,
Prec. Torque: Collective 22, Cyclic 9, Zero Col. 0.

The main rotor it’s perfect but the tail NO.

Does someone know where I could have been wrong and give me suggestions?
Last curiosity: is there really difference between VBAR and KBAR apart the price?
Thank You

I'm new to Vbar and Fltbarless altogether, but to stop the tail from oscillating lower the normal gain.

Here is a good tutorial of the Vbar tail: http://www.rchelination.com/flybarl...arlogo-example/
I made a mistake once, but I was wrong?

One more question,
but can you change directly from your TX the tail funcion from mode "hold" to mode "normal"?
