RE: What you think ???
The drawing on the right shows that it has 2 fins at the end of the stab, the drawing on the left shows a single fin on the fuse. If you are going to use a single fin I would increase the size of the fin or I suspect you will see the fuse hunting in a straight line. I'd shorten the wheel pants up by half too, they look a little odd being nearly the same length as the root chord of the wing. For a speed plane I'd shorten the fuse and move the wing back as well.
