bone doc is absolutely right. the right throttle postiion is the key. steer with rudder.. if you get into using aileron to correct it usually ends up just rocking more.. the rudder correction wont be as abrupt so between that and the throttle you will have it.. some planes however will wing rock slightly in harrier no matter what you do. on those the more you fly it the more you can tame it (practice). to make them not look so bad.
