Feature: 1. Durable Motor: 4 pole rotor design, with strong torque and stable output power, low friction, low noise and high accuracy. Explosion proof rotor, high toughness stainless steel output shaft, high accuracy bearings make the motor super durable. 2. Premium Components: High hardness aluminum CNC shell, high temperature resistant copper coil, 0.2mm thickness silicon steel sheet, high magnetic permeability, high silicon content, good insulation and heat resistance. Strong anti current ability, excellent heat dissipation, built in switch mode 6.1V 5A or 7.4V 5A (switching mode), compatible with high torque and high voltage servo. 3. Waterproof ESC: The all weather waterproof and dustproof design of the ESC, specially designed for RC model cars, has excellent starting, acceleration and linear functions. Suitable for Traxxas, for Wltoys, for HSP 1/8 RC car. 4. Detachable: The detachable structure design is convenient for cleaning and maintenance, effectively prolonging the service life of the motor and improving work efficiency. The motor has a built in temperature sensor and interface, which can be used with the ESC to realize the motor overheating protection function. 5. Multiple Protection: Low voltage cut off protection for lithium or nickel batteries, ESC overheating protection, motor overheating protection, throttle signal loss protection, motor stall protection, easy to program and compatible with pocket sized program cards.
