Futaba S3155 High-Speed Slim Wing Servo (Digital)  [S3155]

S3155 Technical Highlights

The Futaba S3155 is a digital high-speed slim servo crafted for wing-mounted control surfaces on model gliders and small electric aircraft where space is at a premium. The slim black housing and metal gear set give a compact, responsive package suitable for tight installations.

Ensure your power delivery is capable of handling the servo's startup and loaded current. Shorten leads where practical, avoid unnecessary harnessing, and check pushrod alignment and hinge freedom to reduce drag on the servo and prevent premature wear.

For dependable wing control, secure a clean mechanical installation, use the appropriate horn from the kit to set travel and centring, and ensure your power system and wiring are sized to cope with brief high current demands.
