FAQ

Is the HPI SD-07WR servo waterproof? No. This servo is water-resistant only. It can handle splashes and brief moisture exposure, but it is not designed for full submersion.

What torque does this servo produce? The SD-07WR produces 6kg-cm at 4.8V and 7kg-cm at 6V.

What spline does this servo use? This servo uses a 25T spline, so it requires a compatible 25T servo horn.

Is this a standard-size servo? Yes. The main case measures 40 x 37.5 x 20mm, making it suitable for many RC vehicles that accept standard-size servos.

Does this servo include a servo horn? No servo horn is listed with the supplied contents. OZRC recommends checking your vehicle’s original horn or purchasing a compatible 25T horn if required.

Important Notes

  • This servo is water-resistant, not waterproof, and must not be submerged.
  • Before driving in wet conditions, make sure all fitted electronics are water-resistant, waterproof or properly protected.
  • Disconnect non-water-resistant cooling fans before wet running and allow them to dry fully before reconnecting.
  • Lubricate exposed drivetrain and metal parts before and after wet driving.
  • Rinse away dirt, mud or salt residue after wet use, then dry and re-lubricate exposed metal components.
  • Check servo spline count, servo dimensions, mounting hole centres and horn compatibility before installation.
