Futaba GY611_S9256 - GY611 Gyro and S9256 Digital Servo Set  [GY611_S9256]

Gyro + Servo set for model helicopters

The Futaba GY611_S9256 bundle pairs the GY611 yaw-rate gyro and control amp with the S9256 digital servo to provide a complete tail stabilization solution for radio?control helicopters. The gyro uses a high-resolution 12?bit A/D converter and a microcomputer control loop to reduce rudder neutral drift, while the S9256 is a super?narrow?pulse?drive compatible digital servo with a cooled Alumite case.

The package focuses on the mechanical and signal-chain elements that affect tail control: the GY611’s SMM (silicon micro machining) sensor technology and AVCS angular vector control system provide stable angular velocity detection and low output drift, and the S9256 delivers a fast response compatible with Futaba’s narrow?pulse protocols. Together they reduce in?flight rudder trimming when installed and tuned correctly.

This Futaba combination is intended as an RC?scale tail stabilization solution; use the included hardware to mount the sensor and amp inboard of the tail assembly, supply a regulated 4.8V receiver battery, and follow the manual for initial gyro gain and servo endpoint tuning to achieve neutral rudder behavior during flight.
