Compact High-Speed Wing Servo

The Futaba S3155 Digital HS Wing Servo is built for wing-mounted use on gliders, EDF jets and electric sport planes. Its low-profile case fits narrow bays for tidy installs, and the fast response helps precise aileron and flap work during active flying.

Rugged Build and Multiple Horn Choices

This digital servo features dust and water resistance but is not fully waterproof. Inside the black plastic shell are durable metal gears (FUTM3331) designed for extended service life. It ships with several servo horns, including a pre-installed 1" (25.4mm) 4-arm horn, a 1.5" (39mm) 4-arm horn, a 1.75" (45mm) straight horn, and a 1.4" (35mm) diameter round horn for flexible linkage layouts.

Specifications

  • Speed: 0.16 sec/60° @ 4.8V, 0.13 sec/60° @ 6V
  • Torque: 28 oz-in @ 4.8V (2.0 kg/cm)
  • Dimensions: 1.2 x 0.4 x 1.1" (30 x 11 x 29mm)
  • Weight: 0.72 oz (20g)
  • Lead Length: 6" (154mm)

Hobby pilots who need a fast, compact wing servo will find the Futaba S3155 balances speed and durable construction for reliable flight control.

Can I run this servo from an AM transmitter?

No. This modern digital servo expects standard PWM neutral signals and is not compatible with legacy AM outputs, so use a compatible receiver.

What power and wiring should I use?

Use a stable 4.8V to 6V supply and keep lead runs short where possible. If you need longer runs, use heavier gauge servo extension wires to avoid voltage drop and heat.

Which horn is best for aileron travel?

Choose the horn that provides the mechanical advantage you need. The supplied 1" 4-arm horn is good for tight setups, while the larger 1.5" horn gives more throw when you need greater control surface movement.
