Do you think the .061 will be enough, or do I need to go up to a .074 or .09? It looks small in there....

In the meantime, I framed up the tail assembly, awaiting finishing sanding, and built the keel for the formers. It serves no structural purpose other than to serve as a guide for aligning the formers. You can see a rough design for a former right below. This should reduce weight and free up a lot of space. The stringers and sheeting should provide the strength for the fuse.
