Nope, the HV is an Opto-ESC. Meaning it requires brains power from an external source. We are just used to ESCs that have their own built-in BEC. Even when we "disable" it by removing the wire, it still is powering the internal circuits. Any HV ESC will be an Opto design unless it happens to have a switching BEC built-in. The losses of a typical linear regulator are too great after just 3s, and who runs 3s on a 10s-12s controller?
