Do you have a computer radio? If so, you can mix the down elevator trim to your flap setting, so when you set your flaps for takeoff, the correct elevator trim to keep it from pitching up is also set. When you retract your flaps after takeoff, the elevator trim will go to its regular setting; this way you don't have to continually re adjust elevator trim. It works the same way when you use full flaps for landing.

Why use flaps? Because the plane has them, and it's another skill to work on.
