It took a bit for me to realize I now had to dissassemble some of the vertical stabilizer spar assembly to assemble onto the tail cone box. The lower vertical fin spar piece has to be assembled into the back of the tail cone box to get things in place to mount the horizontal and vertical stabilizers and control surfaces.the spacers (2) must be used to hold the upper and lower angles in the proper place for locating the mounting holes, and will then be discarded as the rest of the vertical fin spar assembly is added to the mount.
Here I just have the lower vertical fin spar clecoed into place to see how it all goes together, and how to best assemble the angles into place to drill mounting holes via the pilot holes.
