Very high pitched direct drive motor noise on HW-40
You might think I'm crazy, but HW-40s have always had a very high-pitched noise I could hear coming from somewhere in the motor circuitry as long as the motor is running. It's not exceptionally loud or obnoxious but always noticeable and it's always been there across multiple units so it's not a sample defect.
Does anyone know whether the implementation of the direct drive circuitry in the Avenger Direct and/or Titan Direct also have this noise?
I would imagine they would, unless VPI changed the motor control circuitry for those models, and I don't know why they would have.
