Thanks for the quick reply guys,
I am using the JR 9x2, in the US it is the 9303.
I have reduced the gain in the Gryo setup menu on the Tx.
End points set to 100%, I believe this is right?? Let the Gryo set the travel via the limit pot??
original setup for centre point made in RATE mode, adjusted the pushrod to get steady hover, no yaw.

If the limit pot is reduced is that just effecting full rudder travel, as opposed to gryo sensetivity in centre?

Cheers
