Futaba S9157 Servo for High Load RC Applications

The Futaba S9157 Digital Hi-Torque Servo uses a coreless motor together with dual ball bearings to produce smooth, accurate motion for advanced hobbyists. It is well matched to large-scale aircraft and other models where reliable control is essential.

Key Performance and Build Details

The servo incorporates a metal middle case to aid thermal dispersion and improve endurance under continuous use. It delivers 425oz-in (30.6kg/cm) of torque at 6V and achieves 0.14 sec/60° at 6V for precise, rapid position changes.

Specifications

  • Torque: 425oz-in (30.6kg/cm) @ 6V
  • Speed: 0.14 sec/60° @ 6V
  • Dimensions: 1.6 x 0.8 x 1.5" (41 x 21 x 37mm)

The Futaba S9157 is a dependable option for modelers who need strong torque, swift response and a durable construction for competition or advanced builds.

Yes, the published torque rating indicates it will handle sizeable control surfaces when correctly mounted and paired with suitable linkages.
A stable power source that sustains voltage under load is crucial. Using a regulated BEC or equivalent supply near the 6V rating helps maintain torque and speed figures.
The servo uses a 3x8mm horn screw size, so replacement horns and fasteners matching that specification will fit correctly.
