Brushless verses Brushed Motors

[Shakey]

The throttle is not controlling the RPM though in brushed. It is controlling the effective voltage fed to the controller, capping the throttle means you won't feed it full voltage and hence will lower max power. "the speed increases as the voltage increases" That's normal operation for any brushed DC motor (And the brushless DC motors we use). Motors all have a 'kv' or 'rpm/v' which is a measure of how fast it turns per volt that is fed into the motor.

Brushed is often the simpler route due to the number of already paired motors and gearboxes out there and ESC's made for them being much closer to what we actually want. But brushless, especially these days, easily out performs on a weight for weight basis.
