Tight Tail Response for Futaba GY611 and S9256

If you fly RC helicopters and want cleaner heading hold and quicker correction, the Futaba GY611 gyro combined with the S9256 servo gives a compact, high-response solution. The setup is aimed at pilots who expect steady performance without extra in-flight trimming.

Core Advantages of the Futaba GY611

  • Microcomputer Processing: Dedicated microcomputer arithmetic improves gyro reaction and consistency.
  • Advanced Sensor Technology: 12-bit A/D conversion together with SMM micro-machining helps reduce vibration errors and boosts precision.
  • Heading Hold System: The AVCS heading hold cuts rudder wander and reduces the need for manual trim.

S9256 Servo Characteristics

  • High Response: Super narrow pulse drive delivers a speed of .06 sec/60X for rapid tail inputs.
  • Durable Design: Alumite outer case with an internal heat sink helps keep the motor cool under load.
  • Compatibility: Works seamlessly with the GY611 gyro and other super narrow pulse systems.

Specifications

  • Operating Voltage Range: DC 3.8V to 5V
  • Current Drain: 70mA @ 5V, including sensor
  • GY611 Dimensions: Amp 57 x 32 x 15mm / Sensor 30 x 30 x 18mm
  • GY611 Weight: Amp 34g / Sensor 30g
  • S9256 Servo Dimensions: 40 x 20 x 36.6mm
  • S9256 Servo Weight: 57g
  • Speed: .06 sec/60X (at 4.8V)
  • Torque: 47 oz-in (3.4 kg-cm) (at 4.8V)

A good upgrade path for pilots who want steady heading hold and a responsive tail setup in rotorcraft applications.

Use a 4.8V receiver battery for the S9256 as specified. Running higher voltages risks overheating or damaging the servo.
Yes, the GY611 allows adjustments to match tail rotor sizes and control link geometry; small tuning steps usually yield the best balance between stability and agility.
The S9256 offers high speed and moderate torque, making it a solid choice for many 3D and scale tail applications, but always verify torque needs against tail rotor setup.
