You actually getting a complete motor cheaper than a rotor, perfect item as a spare as you will have a free choice of rotor and a sensor as well, sensor suits EVO II, INSANE IV motors.
This motor got the wrong lazer engraving, it is not a drag motor so we sell way cheaper because of the wrong wording. It suits 1/12 pan car or TC
