Feature: 1. Powerful Motor: The motor has pole 4 rotor design, which has strong torque and stable output power, low friction, low noise and high accuracy. Explosion proof rotor, high toughness stainless steel output shaft and high accuracy premium bearing make the motor super durable. 2. Waterproof ESC: The ESC adopts all weather waterproof and dust proof design, specially designed for RC model cars, with excellent starting, acceleration and linear functions. The ESC is used for sensorless brushless motor with strong current resistance and excellent heat dissipation. The built in switch mode is 6.1V 5A or 7.4V 5A (switching mode), which is compatible with high torque and high voltage servo. 3. High Hardness Aluminum CNC Shell: The motor ESC set has high hardness aluminum CNC shell, high temperature resistant copper coil, 0.2mm thick silicon steel sheet, high permeability, high silicon content, and good insulation and heat resistance. 4. Multiple Protection: The set has low voltage cutoff protection for lithium or nickel batteries, ESC overheating protection, throttle signal loss protection, motor stall protection. The motor is equipped with a built in temperature sensor and interface, which can be matched with the ESC to realize the motor overheating protection function. 5. Removable Structure: The removable structure design is convenient for cleaning and maintenance, effectively prolonging the service life of the motor and improving the working efficiency. And the set is easy to program, and compatible with pocket sized program cards.
