Remove the Servo Horns
Parts List
(2) Parallax continuous rotation servos, previously centered
Instructions
- Use a Phillips screwdriver to remove the screws that hold the servo control horns on the output shafts.
- Pull each horn upwards and off the servo output shaft.
- Save the screws; you will need them again soon.
STOP! Before taking the next step, you must have completed these activities: Chapter 2, Activity 4: Connect Servo Motors and Batteries, and Chapter 2, Activity 5: Centering the Servos.
