Well, I will make it simple brushed motor. What now?

P.S. Motors with low inductance, almost instantaneously response to PWM from ESC. The low inductance may cause excessive current ripple and cause lots of trouble (motor heating, ESC over voltage). This effect increases at lower PWM frequencies where the current may swing from pos to neg during each PWM transition. That is way switching freq. and motor inductance match important.
In real world to gain performance extra inductors are added in between motors and drivers. Not practical for RC.
