Futaba S9257 EP High-Speed Heli Rudder Servo for Gyro Use  [S9257]

High-speed tail servo designed for heli gyro control

The Futaba S9257 EP is a high-speed digital rudder servo built for RC helicopter gyro applications. It is intended to be used with Futaba gyro units to deliver swift, precise tail corrections when linked to a compatible gyro.

According to the product details, the servo is supplied with several horn options and mounting hardware and uses a dual ball bearing arrangement to improve shaft smoothness. The S9257 is for FM, PCM and HRS systems only and must not be used with AM radios.

Installation requires a connection to a compatible gyro, for example the Futaba GY401 series or the GY502. Perform proper tail linkage adjustments and endpoint tuning when integrating the servo into a tail assembly, and confirm travel limits in your transmitter to avoid overtravel issues.

Compatibility

This servo is intended for use with the Futaba gyro products mentioned above and is suited for tail control in electric model helicopters. A gyro must be connected for proper tail authority, and radio compatibility is restricted to FM, PCM and HRS types.

The S9257 delivers compact, high-speed performance for pilots using Futaba gyro systems, offering included hardware and multiple horn configurations for flexible tail setups.
