Savox servo keeps making noise in neutral position

[murky123]

I have a new servo. Brand is Savox. It is the first savox 1256 digital coreless servo I have.
It just keeps on producing a humming sound when I do not steer.
I have tried adjusting the neutral position and subtrim, but with no luck.

the savox has a super high 12 bits (4096) resolution, mabye that is why?

tx/rx is a traxxas TQ 2 channel 2,4Ghz

Is it ok to make that noise?

I have also a thundertiger DS1015 and he does the same but nearly not as much.

They are very noisy but work great and are a bargain, for that I can stand the noise.

Actually you can minimize it by making sure that your steering is free of any binds and that the draglink is at 90 degrees to the servo arm and the tierod is as parallel to the drag link as posible. That should quiet it a little.

I'm having the same problem with my SC-0251, anyone have any other answers to this humming noise?

Most if not all digital servos do this

All of my high torque Savox's hum, no biggy.

Savox digital servos are noisier than most. Nothing wrong with it just noise. High torque digital servos make noise.

The best bet is to remove the servo from the car and throw it into the trash can. Then buy a Hitec and never look back.

The best bet is to remove the servo from the car and throw it into the trash can. Then buy a Hitec and get used to sending it in for warranty when it dies every few months.

Fixed it for accuracy.


Even the hitec digital servos chatter at idle, it's not a problem. I've have fantastic luck with savox. No busted gear sets or smoked electronics, just a broken case which I've done to a few different brands so it doesn't reflect poorly on any brand in particular.

The noise is attributed to the 4096 resolution. Digital servos have a tighter band for where center and positions are..... Hence the buzz to find an imperfect point on the scale. The resolution numbers represent how many points on the scale they have in movement. It's typical for all digital servos to buzz..... Savox more than others..... It's normal.
