The Futaba S9551 Low Profile Digital Servo is designed for crisp, repeatable control in tight installations. Its low height and compact footprint let you tuck it into wings and slim car bays without compromising throw or reliability.

Metal Gears: Robust gearing that stands up to repeated high-load use.
Dual Ball Bearings: Provides steady, low-friction operation for consistent feel.
Dust and Water Resistant: Basic sealing protects against dust and light moisture but is not a substitute for waterproof servos.
