Motor whine with HFI?

I'm running two sensorless motors with the FOCBOX in HFI mode. Controlling the speed via ADC in PID speed control (reverse button).

HFI is working great to start from a stand-still, but the motors have a continuous loud whine from HFI even when there is zero throttle. Is there a way to configure HFI to disable unless a throttle is applied?

That feature is coming in the new firmware update that is currently in testing.

Thanks TechAUmNu - is there a beta version of that firmware I can try out?
