First, I replaced the single rib on the centerline with two ribs separated by roughly 6 inches so that each rib was aligned over the support area on the fuselage/vertical stab. Second, I installed an additional partial spar at approximately 25% of chord (including the elevators). I made this spar out of 1/4" foam core with 2 bid, and attached it with one bid. I ran it out to the ribs in the middle of the span. It's something like 24" long, but I can't remember without digging out the progress photos. I also installed some nylon tubing inside the horizontal stab so I could install a wire nav antenna later on if I wanted. But it is probably impossible for me to reach that area of the tail cone now even if I wanted to. Sounded like a good idea at the time...
