I think you are right. Once motor is going ESC calculates correct phase using back EMF. But bigger peak energy calls for increase ESC rating.
Well, when we are running 490Hz update cycle, would it make a difference if ESC reacts instantaneously or say with ramp-up time of 10-20ms?
And we don't counting motor+prop inertia... What do you think?
