Futaba GY520_S9257 Precision Tail Gyro and S9257 Fast Digital Servo  [GY520_S9257]

Tight Tail Control with Futaba GY520_S9257

The Futaba GY520 Heading Hold Gyro combined with the S9257 High-Speed Digital Servo provides a compact, capable package for RC helicopter pilots focused on accurate heading hold. This combination adapts well between F3C precision and dynamic 3D flying.

High-Speed PID Stabilisation

The GY520's design integrates sensor and control circuitry in a small footprint to keep weight down. A high-speed PID algorithm gives the unit swift correction capability, and MEMS integration on a single chip improves stability and lowers long-term drift.

Flexible Servo Support and Frequency

Compatible with both analog and digital servos, the GY520 supports 280Hz at 1520uS and 506Hz at 760uS operation. These modes help match the unit to different servos and ensure solid AVCS-based tail holding performance.

Accessible Setup Methods

Setup can be done with the GY520's single-button and LED status system or via PC when using the Futaba CIU-2 USB adapter, allowing straightforward configuration for a range of skill levels.

For pilots wanting accurate tail behaviour and responsive corrections, the Futaba GY520 and S9257 offer a compact, reliable pairing that handles both precise and 3D flight demands.
