Wag Aero's fuselage

Having rebuilt several J3's, I am thinking about building up an experimental Cub using Wag Aero's tack welded fuselage. I have been waiting for info from Wag Aero, in the meantime, does anyone have any experience with them? Especially, is it an exact copy of a J3, or did they add a little cabin room, as in a PA 18? Thanks, Joe

Its a direct copy, except its chromemoly, not mild steel. Also they use a tab on thier elevator for trim, rather than the jack screw. They can put in the jack screw mount.
