Electric motors and regulators
The electric motors differ in brushless and brushed. There is a separate controller for each of the two motor types. Without a regulator, the engine would either not move or full throttle when turned on. Brushed motors and regulators are indeed cheap to buy, but also less powerful and do not last so long. Brushless motors, are very powerful, fast and have a long product life. While brushless motors and the matching ESCs do not have a real expiration date, the brushed equivalents will wear off the coals and anchors depending on usage. Visually, the brushless motor is recognized by its closed motor housing and the three outgoing cables, while the brushmotor has ventilation holes and only two motor cables.
