Yes you are quite right there is a weight saving even taking into acount the 10% increase in tail area added to allow for the decrease in planform area for the dihedral on the tail plane.

Yup, the top mounting looks better but the lower mounting using the V to locate the tailplane, is more practical & saves work
Most comp flyers seem to prefer X tails but I like V tails. There only disadvantage in my eyes is there lack of steerage when in landing configuration with only rudder for steering. Works best with full crow breaking.
