Some of the cheap brushless ESCs have an option to control "Top Speed" with one Pot with another Pot controlling acceleration. Given there is no good way to know motor RPM on a sensorless motor I'm wondering how this is achieved? Given these cheap brushed 550 motors double their speed going from 12 to 24v, I'm wondering if there is a way to cap voltage (top speed) while not impacting the acceleration.
I'm using Duty Cycle in the ADC Settings and DC settings are all default.
