The elevator control rods are combined together using the supplied joiner. Each end is bent at a right angle to keep it from slipping out under force. I used Pacer Z-42 thread locker on the three nuts before tightening them in place.

The elevator and rudder control horns were mounted into the pre-drilled holes of the control surfaces. All the hardware was supplied and the pre-mounted tubing ends even had the fuselage covering sliced at the opening so the control rods could slide through. This provided a very clean look. However, I needed to open the holes in the control horns for the clevises using a 5/64" bit. All three clevises were installed into the second hole from the outside or second farthest from the control surface.
