Accurate Control from the Futaba S9650 Mini Servo

The Futaba S9650 Digital Mini Servo provides a reliable mix of torque and speed for 1/12 and 1/18 on-road cars. Its digital control and coreless motor help produce consistent steering inputs for precise handling.

Coreless Motor Performance

The coreless motor in the S9650 removes the weight of a conventional armature, resulting in a lighter rotor that responds more quickly. That faster shaft response helps keep steering crisp under dynamic driving conditions.

Reliable Nylon Gear Train

Equipped with nylon gears, the servo maintains smooth operation and good wear characteristics during regular track use. The gearing focuses on dependable centring and reduced friction for longer intervals between services.

Fitment, Hardware and Compatibility

Intended for 1/12 and 1/18 on-road vehicles such as the HPI Micro RS4, the servo comes with four rubber grommets, brass eyelets for mounting and a 21mm round horn to suit common linkage styles.

Specifications

  • Length: 43mm between centers of side mounting holes
  • Servo Body Length: 35.5mm
  • Width: 15mm
  • Height: 28.6mm
  • Weight: 26 grams
  • Speed: .14 sec/60° @ 4.8V, .11 sec/60° @ 6.0V
  • Torque: 3.6kg-cm @ 4.8V, 4.5kg-cm @ 6.0V

Recommended for modelers seeking compact, high-torque performance; for best results run the Futaba S9650 at 6.0V when your system allows.

Measure the side mount hole spacing of your chassis and compare it to the 43mm centre-to-centre spec, and confirm the body height and width will clear your servo bay.
Yes, the digital control and coreless motor reduce jitter under rapid inputs, provided your radio and power supply are stable and the servo is properly mounted.
The 21mm round horn is versatile for many linkage geometries, but for very tight turn ratios you may prefer a different horn or a servo saver to fine-tune throw and mechanical advantage.
