Can Brushless ESCs be used as limiters.
Can Brushless ESCs be used as limiters, set to a precise power output limits when connected to the same model motor.
Given the electronic nature and the precise linking of motor RPM and the output of the ESC, and the elimination of variables like comms, brushes and springs) wouldn't it be possible switch the ESC between say low med and high, or stock spec,19t spec and mod spec, or simply have adjustment screw/pot and a LED readout of the output equvalence in turns.
However it is done you could have one motor and one ESC capable of being used for multiple classes.
also you could instigate a handicap system for club races, where the winner would have to adjust out a click of power and/or the losers up a click.
