I roughed in the top block over the fuel tank compartment. I felt I needed some ideal of how it might interface with the cabane struts.
Speaking of cabane struts, I am in the early process of working on them.
I installed the mount points and blind nuts in the top wing. There are only two attach points and nuts in the top wing. The cabanes will bolt onto the center line, one forward and one aft. The opposite side will make an inverted V, and will be in the usual N layout. The bottom ends of the struts will be epoxied into the fuse. Seems simpler and maybe lighter.
The Struts will be built just like the other two were, 4 40 rod into the same size hollow carbon fiber rods. Well on the top any way. The 4 40 rods are bent into a V, for both the front and back. The front 4 40 attach rods exactly the same as all the others were, But then soldered together to give me the needed four legs.
