Should a new 120$ servo be making this noise?

Its a brand new JR 9001. This was the first time it was used.

My 9100t only sounds like that when it's strained. You might want to check that your steering linkage isn't binding.

I'm at work and can't listen to the video but servos usually do make some noise, especially when strained at their limits but can make all kinds of noises even when not strained.

For the most part it's ok. I've been using digital servos in helis for 10 years now. We call them "nervous servo's" because of the noise they make. Just make sure the end points are adjusted correctly. To do this put youre radio on the EPA or ATV screen (depending on radio) Turn the wheel all the way to the right and make sure that it's not binding, or pulling it too far. Then back it down 3%. Then do the same for the left. Sometimes the endpoint numbers can be different.

Yeah, I have two of them... a 9100s and 9100t and both do that. One on the steering and one on the throttle/brake.
Listening to your video your 9100 acts just like mine. Buzzing at the ever so slight force against it. You can take your finger and slightly touch the servo arm to make that noise happen. When your turning your wheels sometimes it's quiet at neutral and sometimes it makes a buzz. Just means there is very slight pressure remaining on the arm.
If there is absolutely no resistance, and I mean NONE, it will go quiet just as
your video shows.
I think your servo is fine.
BTW, the sound acutally helps me set my end points.

I just wasnt sure if that was 'healthy" for it or not.

ya thats perfectly normal...my hitec 5995 in my revo makes a ton of noise and it seems the more torque the servo has the more noises it makes so thats perfectly normal just make sure your EPA's are set right otherwise that 120 dollar servo will burn out very quickly
