Found on traxxas site.
The Titan 12T 550 modified motor is designed for incredible mod-motor power output with virtually maintenance-free operation, and long-lasting performance. The Titan 12T 550 motor’s integrated cooling fan pulls cool air through the motor to keep temperatures down.
Airflow is routed through vent tunnels molded in the motor plate. A cooler running motor equates to faster speeds, longer runtime, and extended motor life. The XL-5 Electronic Speed Control offers high current handling, EZ-Set® one-button setup, and smooth high-frequency control. Three drive profiles, thermal shutdown protection, gold-plated connectors, and incredibly low resistance are all features you might expect to only be available on an expensive replacement ESC. As today’s batteries store more and more energy inside their cells, traditional battery connectors could no longer keep up. The included Traxxas High-Current Connector opens the door for unrestricted current flow.
I didn't read that well enough the first time.
