Saitek stick/throttle....rudder issue

Hey,
This is a pretty good stick/throttle combination, but it causes a quirky
behavior in that the aircraft rudder becomes very unstable on takeoff roll.
It slips from side to side, making takeoff a real challange. I'm pretty new
with this stick and would appreciate if anyone else having this problem
could give some feedback on it.

Thanks,
