Rudder
Elevator
Install rudder and elevator servos as shown. Note: Use 18-24" servo extension.
A NOTE about servo arms on the 72" SC. The Extra 330SC uses ball-links on its controls for precise control-
surface motion. It is extremely important to make sure that the ball-links have free motion throughout the servo
travel, and do not touch the servo arms. For example, when using Hitec servo arms, this is easily
accomplished by cutting or sanding away the corner of the arm as shown.
