Precision Flight Control with Futaba GY520 and S9254

The Futaba GY520 Gyro combined with the S9254 Digital Coreless Servo gives model pilots precise tail and cyclic control for advanced RC helicopters. This matched set focuses on quick response and consistent stability during demanding manoeuvres.

Compact MEMS Gyro for Stable Tail Control

The GY520 uses a compact MEMS sensor and a refined PID control loop to keep models steady. It supports selectable F3C and 3D modes plus six programmable parameters, making it straightforward to tune for a range of flying styles and both analog and digital servos.

Rapid Coreless Servo for Sharp Inputs

The S9254 Digital Coreless Servo features a lightweight coreless motor and a dual ball bearing gear train for crisp, low-latency movement. Its dust and water resistant design increases durability, making it suitable for helicopters that demand frequent, precise corrections.

For pilots trimming a helicopter for tight control or freestyle flying, the Futaba GY520 and S9254 combo offers reliable tuning options and fast servo response to dial in precise handling.

Begin with neutral PID values and F3C mode for general stability, then incrementally adjust the response to match tail authority and rotorhead setup.
Yes, the coreless motor and dual ball bearings provide quick actuation and consistent performance under frequent, high-rate commands typical in 3D flying.
Regularly check servo linkages and seals, clean dust from the gyro area, and verify power connections to maintain accurate sensor and servo performance.
The GY520 integrates with standard receiver and flight controller configurations; confirm signal polarity and range before final installation.
