I put an Airtronics 94773M servo for throttle/brake and a 94771M servo for steering in my buggy. This is my first nitro buggy build, so please excuse my "noob" question haha. How much static do servos normally make? When I turned the receiver on for the first time just now, there was a bunch of static noise coming from the servos. Is this normal? The servos are performing normally, receiver battery pack is 6 volts.

That sound is normal for digital servos. nothing to worry about.

Okay thanks. These are my first digital servos so I appreciate the clarification.

Once the servos center themselves they shouldn't make any sounds. They only make noise when there is a load on them.

how to differential a good servo. a servo should centralize without any sound. it's normal to have some sound on power on.

if it shaking or rattling while centering like retries. there is something not right.
