Trim?

[mondo]

trim used to counter the lift of the wings to keep level flight and the torque of the propeller.

German planes typically only have elevator trim and have the other trim preset on the ground using flettner tabs. Most British planes have rudder and elevator trim and most US planes have trim on all three axis.

Trim is massivly important, it means the pilot can 'dial in' a direction they want, it also means that they are not fighting the stick to keep the plane straight/level or at a desired angle. In real life this means a pilot on a 4 hour sortie isn't fatigued by having to keep a constant 10lbs or more pressure on the stick of rudders.
