Features: *Integrated cooling fan of the motor pulls cool air through the motor to keep temperatures down. Heat-resistance running motors allow faster speeds, longer runtime, and extending motor life. *With precision-balanced rotor, smoothness for best reliability, and maximum RPM. The motor is suitable for racing cars trucks Replacement for TRX 1/10 SLASH. *This 60A ESC is compatible with a brushed motor and suitable to1/10 remote control Car. And it has protections of Lipo battery low voltage, cell quantity autotest, high-temperature protection, throttle signal loss protection. *The ESC possesses an aluminum cooling system offering excellent heat dissipation a strong resistant current capability. Also, the high-quality components of this ESC allow it splash-proof anddustproof, which is durable. *The ESC has a forward and reverse mode which means forward, reserve and brake, for the daily practice purpose. The mode backs the car with a double click, when the throttle moves to neutral and moves twice reversely (means double clicks), the motor would stop running. It still brakes instead of backing. Need to move throttle to neutral and move to reverse to make car backed. Double click mode is applied to avoid that many times of brake cause wrong back. *After-sale Service Guarantee: Any problem, please contact our store without hesitation. Honor to serve you.
