A plane question.

Put VERY simply the offset is there to counteract the effect of the swirling air of a rotating prop hitting the tailfin like a corkscrew, producing more pressure on one side of he fin than the other.....and effectively "yawing" the 'plane to the left - it also helps to counter the torque effect of the model trying to rotate around the engine.
