Default CG

There are two reasons for filling in the wing planform between the insides of the elevons. First, is that it will make your CG calculations valid. Second, It will improve performance appreciably by improving the profile drag of the wing center airfoil where it ends bluntly and it will also reduce induced drag because of a better lift distribution.
