6. Install the pulley axle hardware.
7. Place a small weight on the stabilator to hold it trailing edge down. Remove the
slack from the upper cable by tightening the upper turnbuckle until the control
stick and stabilator just start to lift off the stops at about the same time when the
stick is moved aft.
Remove the slack from the other cable by adjusting the lower turnbuckle. Check
the entire length of the cables to ensure they are free from interference, are
properly aligned in the pulleys, and do not touch each other. Pull the stick aft to
make sure that the stabilator trailing edge moves up.
