I found this setup to be less stable than other methods. Heavier as well. Much harder to install.

I prefer to run a normal Y push rod with bushings where the push rods exit the fuse. This approach keeps the push rod centered in the plane and imparts the exact movement to the Elevators without any side to side or up and down flexing. I used short piece of inner and outer Ny rod as the bearings. The outer is glued to the fuse side, the inner is glued to the push rod. Simple, cheap and light, easy to install even on an airplane that's fully built. I've fixed many airplane tracking problems with this method, even those with the afore mentioned push rod set up. Think of it as a early version of the Deps setup.
