Very nice work. Make sure those new servo rails are well secured. Can't tell if they conform to the the bottom of the fuse, or are just glued to the sheeting on each end. Might want to build a lighter ply structure with two full-depth formers and a top plate with servo cutouts...you could lighten further by drilling lightening holes in the structure.
I'm anxious to see the interior possibilities without the boxy intrusion. Pedals, etc. Should be cool.
Enjoying your show.
