The only time I can see where holding a rudder input to combat a crosswind would be in a side slip situation.

With wing banked slightly into the wind and holding opposite rudder to prevent the aircraft from turning into the bank direction.

This is a valid technique for flying an approach to landing in a crosswind. (Generally used by light aircraft)

Otherwise if your goal is to fly a ground track in a cross wind then offset the heading. Once that heading is set the plane should be flown in balance. I do understand that you can make minor corrections with rudder to adjust that heading but once set the rudder can be returned to neutral and heading should not change. The plane is moving with the air at all times so there is no "weathercock' effect in steady winds. Varying gusts are a different story,

As for the comments about 'professionals' staying out of the beginners forums. I think most beginners are happy to get advice from more experienced people.

I know I always appreciate the words of an 'expert' when I ask questions about topics that are new to me.

If beginners only want advice from other beginners then it becomes a case of the blind leading the blind.

But remember we are here to help each other and should try not to brow beat one another.
