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.

How to Properly Soak Water Gel Beads

  • Prepare a container and add plenty of clean water to fully submerge the water gel beads.
  • Soak them for 4–6 hours until the beads expand, soften and become fully plump.
  • Keep the beads completely under water during the whole process; otherwise, they will not be fully soaked and may easily cause jamming.
  • If the soaking time is insufficient or there is not enough water, some water gel beads will not absorb enough water, which may cause poor firing or jamming.
