Hey Steveb,
I, too just completed that section of building this plane.
Put the battery tray and walls in, and top formers F4-F6 in all at once, it's the easiest way. I also beefed up this area, because i didn't like all of that weight on top of that single sheet of balsa.

I have to update it tonight with pictures of the formers in, tray installed, and stringers on.
I don't see the "balsa fill" for this area on the plans either...
I have a question on how the Rudder is securely glued in. Per plans and instructions it looks like it just sits on top of the stringers!? Then you're told to spackle the fillet!? I must be missing something...
Pat's really good about answering questions, I'll ask him too.
Email me if you wish at:
