Just got back into racing after about 10 years or so, alot has changed. So I picked up a orion vortex digital servo for my 1/10 scale buggy, when I hooked up the servo it seems to be making a noise sounds like it could be from the digital signal, I'm using a airtronics m11 2.4, I was just wondering if this is normal?

It's a digital servo so that noise is perfectly normal. I run Team Orion servos in my 8ight and love them. They are actually the same as the Savox servos.

the noise nearly similar to the KO Propo digital servo. It's norm for digital servo.
