Not sure what you mean when referencing the rudder, but if you're talking about the offset to the left at the point that where the fwd VS spar bolt attaches, I think that is intentional (it is shown in the plans). In my experience, most previous RV models have tended to need a bit of right rudder trim in cruise. Offsetting the LE of the VS to the left will help provide a bit of nose-right correction and hopefully negate the need for a trim tab to keep the ball centered in cruise.
