swinging aircraft

[Capt.S.Prest]

i've been flying FS for about 4 years now but i won't say i'm that good. anyways i noticed something odd while i was flying today...i was climbing to my cruise altitude and my speed was about 265 KIAS....i noticed my plane kept swinging left to right like a pendulum..after about 2 mins of trying to figure out what was wrong, i increased speed to 400 KIAS and everything was fine....during my approach, as i lined up with the runway and had full flaps and gear down, it started again..

does anyone hav any clue why this hapened and it's not the aircraft because i've flown that aircraft several times without this experience

you might need to recalibrate your rudder controls.

Need a little more information.

1.  What aircraft?
2.  What altitude?
3.  Real world weather?
4.  When you say left and right, are you talking about roll, or like you are using the rudder?

Try adjusting your control sensitivities, set the "null zone" higher, this way it will avoid tiny movements of controls. Was the aircraft an addon or an fs default?

Wind shear (although I would think that would be more of a yaw issue)?

Sounds like Dutch Roll.

Do you have the yaw dampers on?
