rc queston

I just bought my first truck. when the battery is fully charged the motor makes a high pitched humming noise which eventually goes away when the battery weakens. Is this normal?

Most likely, it could also be the ESC making the noise. I assume all is working the way it is supposed to?

If all is working well, there should be no issue. This setup is most likely brushed?
