Simviation Forums

So I finally booted FSX up after months of not playing due to other commitments (although I have been flying in real life).  I've been attempting to fly the 172 in fair weather, but every time I level out, the aircraft starts a slight bank to the right.  I've turned the realism settings down, unplugged the rudder pedals, recalibrated my yoke, and yet the problem still persists.  Any idea as to what I am doing wrong?

Does it happen with all aircraft or just the 172?

I think this is a sim problem, not a technique problem... I've had the same thing happen with FS9, for no apparent reason.
I've gotten rid of it by deleting the FS9 cfg file, but once I had to re-install FS9 completely to fix it.

But I don't know diddly about FSX...

I won't move this, but you should definitely post your question in the FSX forum.

A couple of things come to mind...

The rudder trim could have been set a little to the right, during a flight, and then saved that way..

A aircraft with a fuel selector could have been left on one tank . Sometimes in FS9 you could fly a plane like the Howard.. manage your fuel and then load up a C172 and even though the fuel selector was set for "both", your subsequent flights would be taking fuel from just one tank..

If the fair weather theme in FSX is the same as FS9, there would be a little breeze that goes along with it. Does this happen when the weather is clear?

(Probably considered that already, but just in case you hadn't)

Steady wind will not push the airplane in cruise... the airplane moves with the wind. So I don't think wind is causing it to roll.

Suggestions
recalibrate joystick
check torque and p-factor settings in realism
did some addon overwrite yout fuel tank switch (making it a left / right affair)

I've have this happen in FSX with several aircraft, if its your joystick check to see if the yoke in the cockpit is moving slightly, because thats what happened to my joystick, but I re-calibrated it and all was well
