Product Details & Advantages

• CNC Aluminum Housing: The anodized CNC aluminum case enhances structural strength and heat dissipation, reducing vibration during operation for improved stability.
• Coreless Motor Performance: Compared to traditional iron-core motors, the coreless motor offers faster response and lower noise. Combined with metal gears, it delivers smooth power output and excellent wear resistance, preventing gear stripping under heavy use.
• Wide Voltage High-Voltage Drive: Supports up to 8.4V high-voltage input for significantly improved torque and speed, perfect for aggressive driving in micro and drift cars.
• Low Deadband Precision Control: With only 2μs deadband, the servo offers ultra-precise control with zero slack, enhancing handling feel in RC models.
• Programmable Function: Customizable parameters allow adjustment of travel range, speed and more to suit different models and scenarios.
• Lightweight Fit Design: The 9.8g ultra-light weight and compact dimensions fit perfectly in MINI Z and other micro RC car mounting positions without modification.

Application Scenarios

• Servo upgrade for MINI Z and Q series drift cars
• Control for 1/28 scale RC cars, planes and boats
• Arduino and DIY robot projects
• Other RC applications requiring micro, high-speed, high-torque servos

Usage Notes

• This servo is not waterproof. Do not use in wet environments to avoid circuit damage.
• Adjust the servo to the center position before installing the servo arm to prevent jamming.
• Use within the 4.8V-8.4V voltage range to avoid motor burnout.
• The programmable function requires a dedicated programmer. Verify compatibility before use.
