Futaba S3171SB Compact Digital S.Bus Servo  [S3171SB]

Slim digital performance from Futaba S3171SB

The Futaba S3171SB is a slim-profile digital S.Bus servo built to give hobbyists accurate, repeatable positioning in cramped installations. Its compact footprint suits aircraft, cars, and other models that need precise control without bulk.

S.Bus integration and easy programming

Designed for use with Futaba S.Bus systems, this servo can be configured using the SBC-1 Channel Setting Tool, an S.Bus receiver, or PCLink software. That flexibility makes setup and fine tuning straightforward for pilots and drivers alike.

Long life from dual ball bearings

Dual ball bearings reduce internal friction and help the Futaba S3171SB run smoothly under load, which contributes to consistent performance and extended service life during frequent use.

Included horns and fittings for quick fitment

The servo ships with a selection of horns and mounting parts, including a 1" (26mm) 4-point horn, a 1.4" (35mm) round horn, a 1.5" (39mm) 4-point horn, a 1.8" (45mm) double arm horn, plus grommets, eyelets, and screws to simplify installation.

For RC hobbyists wanting precise, programmable control in restricted spaces, the Futaba S3171SB is a reliable choice that balances size and capability.
