Hi, Congratulations on your extra, i`m currently building one, i decided to make a modification to the tail by ading an airfoiled vertical fin and modifying the actual airfoiled stabilator, i have made the modification in other kits and the results are awesome. if you like we can exchage information share some tips etc, write me on [email protected]. as i can see yo can still add a new airfoiled tail to your model, if you like to i would send you the plans and how to make it

best regards.
