SOKOL1: To stabilize a rolling tendency in an airplane with ailerons that are not moving, such as during "hands off", wings level flight, adjust the rudder trim. Observe the turn & slip indicator and add rudder trim until the slip indicator is centered. This will remove the rolling tendency until you change a control element like pitch, bank, power, or prop. CLoD has a great cheat in the "T" key, which will center the rudder trim for you.

This gets to be a nuisance during constantly changing attitude or power, so get it close with the trim and then use your feet on the rudder pedals to adjust as necessary to center the slip indicator. Since many slip indicators look like a tiny ball suspended in fluid, the common term, "step on the ball", is the memory aid for which rudder to apply. (i.e. if the ball is off center to the right, step on the right rudder until it centers). If you have no pedals, you can try the rudder keyboard controls, but you will have a distinct disadvantage in a fighter plane.

I have the rudder trim assigned to an axis knob on my throttle controller, but it is very sensitive and requires practice to master. The rudder is a wonderful thing and is well worth spending a little time on the web to study all the things it can control.
