It would certainly help more to know what sim you're using.

On the other hand, it might not be the sim. Dropping the nose in turns is one thing I work on with some of my students. It's a timing thing that depends on the model being used, it's speed and how the pilot moves the sticks.

If you pull elevator a bit sooner or a bit more the next time you come into that same turn at that same speed, you just might not see the model's nose drop. If you roll the model a bit less next time, you might not see it drop the nose. If the wind is gusting in the right direction.... if the wind is gusting in the wrong direction..... If you fly faster next time......

Lots of things matter. We often judge our model's speed by how loud the motor/prop sound. My sims don't sound anything like my models. That can cause us to fly our sim models at much different speeds than our real ones.

Lots of things can cause the difference you see.
