Sensors are the norm and required in many industrial applications for brushless motors. They provide maximum torque at a stalled condition just like a brushed motor and won't switch to the next set of phases until the rotor gets there. Ideal for RC cars.

Sensorless works in RC planes because we don't care if the motor stutters SLIGHTLY at start up and the prop doesn't need maximum torque to start spinning.
