The Xerun XR8 Pro G3 Brushless ESC and motor combo is Loaded with cutting-edge technologies and features, this 1/8 competition combo is designed to provide a higher level of performance and reliability for all competitive racers looking for the ultimate smooth control and supreme power you’d come to expect from Hobbywing! For added protection, this ESC (Electric Speed Control) is equipped with advanced thermal protection and reverse polarity protection. These advancements allow for an ESC that is designed to outperform the competition. Use appropriate settings provided by the factory or team drivers. Check the operating temperature in order to maximize your electronics. The wrong settings may damage the ESC or motor. Smart freewheeling technology enables the ESC to have higher drive efficiency and lower operating temperature. Compared with the XR8 Pro G2, the maximum temperature is reduced by approximately 59F. Advanced Turbo and Boost timing technology. Built-in reverse polarity protection circuit. Real-time data recording function, easy to obtain power running status. Capacitor thermal protection is designed and implemented into the ESC and will effectively prevent capacitors from exploding and causing irreversible damage to the ESC due to overload.
