Centering a Servo

While it sounds simple, centering a servo is a task that many do not know how to do properly. It's a rather simple procedure, but if done incorrectly it can cause improper steering or possibly throttle control, if you are using a MSC. Follow the steps below to properly center your servo.

• Remove the servo saver, or servo horn, if it's attached to the servo.
  
  
• Make sure you have a fully charged battery powering the RC vehicle and have the truck itself turned on.
  
  
• Turn on the radio, and adjust the trim for the servo you're working with to the centered position.
  
  
• Now install the servo saver/horn as close to centered as possible on the servo. If you have a servo with an insert, you can place the insert on first or you can push the whole saver on as one piece. It's not necessary to remove the steering linkages before doing this.
  
  
• Install the screw that secures the servo saver/horn, and tighten it down. If you have problem with the screw backing out while you run your truck, a drop of blue lock-tite in the servo output shaft will help keep the screw in place. Do not do this with a plastic geared servo, as the lock-tite will weaken the plastic over time.
  
  
• Fine tune the servo center position using the appropriate trim knob on the radio.
