So TopCap or Sledge?
If your building the plane I would go w/ the sledge. right now its probably the hottest little profile on the market. I saw the designer Jeff Williams fly it this weekend at the Profile Brotherhood flyin. Its no doubt that is a great flying plane. but Jeff is definately a better pilot than I am.
I own the top cap ARF. I am not that happy w/ it. its a Pig compaired to the kit built sledge. Mine weight 5.5lbs. Were jeff said his Sledge weighted in at 4.1lbs. He does the sweetest elevator w/ his sledge.
