Gordon,

Don't know if these will help, but here's a few pics off the tail bracing on my old Lanier Giant Stinger that I had. The tail feathers sound like they are fastened to the fuse just like your Cap"s. I used 2-56 wire and bolts. Dubro metal clevis with one side cut off, hole drilled out for bolt. I'm sure you could use CF rod to lighten it a bit. This was back in the old days before CF was used very much.
