Feature: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 100C, 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.Specification:Item Type: RC Car Brushed Motor ESCMaterial: Iron, Plastic, Copper550 Motor:Use Voltage: 7.4-12vMotor Length: Approx. 57mm / 2.2in (Without Shaft)Motor Diameter: Approx. 36mm / 1.4inShaft Diameter: Approx. 3.175mm / 0.1inMotor Shaft Length: Approx. 16mm / 0.6in65A ESC:Battery Support: 5 9Ni MH, 4 6Ni Cd (4.8V-7.2V)Li Ion Battery 2-3S: 7.4V-11.1VBEC Output: 5V 2A (Power Supply For Receiver, Servo)Function: Forward, Brake.
