42KG High Torque Brushless Digital Servo, Full Metal Gear HV Waterproof Servo for RC Crawler/Mechanical Arm/Drone DJ6

Key Selling Points

• 42KG Ultra High Torque Output
  Delivers up to 42kg/cm torque at 8.4V and 38kg/cm at 7.4V. It handles heavy-load applications like RC crawlers and robotic arms easily without slippage under aggressive operation.
• Stainless Steel Gears + Brushless Motor
  Equipped with stainless steel gear set and brushless motor for high transmission efficiency, low noise and longer service life. Much more durable than standard brushed servos.
• Wide Voltage & Precise Control
  Supports DC 5.0-8.4V wide voltage input. Digital signal ensures zero-backlash positioning and fast response for smooth control.
• Metal Housing with Efficient Heat Dissipation
  Heavy-duty all-metal case with heat dissipation structure features great pressure resistance. It dissipates heat quickly during long operation to maintain stable performance.
• Rich Accessories for Out-of-the-Box Installation
  Comes with multiple servo arms, mounting screws and washers. No extra parts needed, easy to fit most RC vehicles and mechanical arms right out of the box.
• Multi-Scenario Hardcore Compatibility
  Ideal for RC crawlers, off-road trucks, drones, robotic arms, automation equipment and DIY modification projects.

User Guide & Precautions

• Confirm the servo voltage matches your device's power supply before installation to avoid damage from overvoltage.
• Perform center calibration before first use to ensure control signals match the servo travel range.
• Do not forcefully tighten the servo arm during installation to prevent damage to gears or the output shaft.
• Monitor the servo temperature during prolonged high-load use to avoid overheating-related performance issues or damage.
• This servo is IP65 splash-proof, do not immerse it in water for a long time. Please seal wiring connections when used in wet environments.
