•
Use Fig #20 as a guide. The servo horn needs to
have one of the outside holes enlarged. Using a 5/64"
drill bit, Phillips-tip screwdriver, or hobby knife, gently
enlarge the hole slightly. When using a knife, carve
from each side to keep the hole even.
•
Test the hole size by inserting the actuator rod
through the hole.
•
Compare your work to Fig #21 then proceed to
Step #12.
Note: The pictures in the remaining steps show only one
servo horn arm for clarity.
•
Attach servo brackets to servo with 4-40 screws and
nuts. Make sure the metal brackets are placed below
the plastic servo tabs as shown in Fig #22.
•
The final assembly should match Fig #23. Double
check your work, then proceed to Step #13.
Note: Only one arm of the servo horn is shown for clarity.
