I agree with @Bricks, I never add an any weight to get the correct CG. With the Versa, I do a trial CG. Build the plane and place it on the CG stand. Tape everything in place where you think it will go, then move thing around until you can get the plane to balance.
To get the battery where I want it, the motor needs to come forward 2-3 inches from the stock position. They cut away the foam to make room for the prop, similar to what they did on the Arrow.
