Good rudder practice and a bit of fun to boot. When you get the airplane in the air, sim or real, do flat turns. ie... turn the plane with the rudder while keeping the plane level with opposite aileron, this is good practice for cross wind landings without putting your plane at risk. You will learn how to keep your wings level while the airplane makes needed rudder turns to stay lined up with the runway.
Play around with the rudder and ailerons while in the air and it will make you more comfortable using them when landing.
