Features 1、HIGH PURITY COPPER WINDINGS: RC car bushed motor ESC uses high purity copper windings and sealed bearings to produce less heat, more power, less friction and less noise. 2、MAXIMUM ENERGY CONVERSION: 550 brushed motor for precise and maximum energy conversion. The rotor is precisely balanced and stable for increased reliability and maximum speed. 3、IMPROVED EFFICIENCY: High purity copper winding maximizes brushed motor efficiency and high strength magnets provide stable brushed motor performance. 4、MULTIPLE PROTECTION FUNCTIONS: 65A brushed ESC has multiple protection functions, ESC with strong current resistance and good heat dissipation. Long service life, a good choice for RC car replacement. 5、OVERHEAT PROTECTION: When the temperature reaches 100°C, the output power decreases and the speed slows down, when the temperature drops, the speed will return to normal. 6、HIGH POWER: 65A waterproof brush ESC compatible with brush motor with for Tamiya white plug, high power, can be used for different types of ships or cars.
