Compact Futaba S3157M Digital Micro Servo for precise control

The Futaba S3157M Digital Micro Servo is a compact solution for builders who need reliable, repeatable movement in small RC platforms. It offers a strong balance of speed and control without adding bulk.

Drive Performance

Designed to perform efficiently, the S3157M delivers useful speed and torque for many small-scale tasks. At 4.8V it runs at 0.1 sec per 60 degrees with 1.5 kg.cm torque, and at 6.0V it reaches 0.09 sec per 60 degrees with 1.7 kg.cm torque, giving extra responsiveness when needed.

Form Factor and Fit

At 21.8 x 11 x 23.2mm and weighing 7.9g, the Futaba S3157M is ideal for cramped installations. Its micro profile lets you mount it in narrow bays while keeping precise control over surfaces or steering linkages.

  • Speed: 0.1 sec/60 degrees at 4.8V, 0.09 sec/60 degrees at 6.0V
  • Torque: 1.5 kg.cm at 4.8V, 1.7 kg.cm at 6.0V
  • Dimensions: 21.8 x 11 x 23.2mm
  • Weight: 7.9g

Is the Futaba S3157M good for lightweight servo mounts?

Yes, its low weight and compact size make it a good match for lightweight mounts on gliders, small foamies, and micro cars.

Can I use this servo with a 6.0V BEC for better response?

Using a 6.0V supply will increase speed and torque, but ensure other electronics are rated for that voltage before switching.

What should I inspect during routine maintenance?

Check horn tightness, wiring for chafe, and smooth travel through the range; any binding or noise can indicate the need for service or replacement.
