JR Propo S89HR 2K N760, Futaba spline 25T

Output gear with Futaba spline (25T).

Brushless helicopter rudder servo.

By default this servo is set-up with 760μSec neutral. Can be changed to 1500μSec or 1520μSec with servo programmer.

XBus Programmable Full Metal Servo Series introduces brushless servos exclusively for heli rudder. Quickly responds to gyro control by optimizing control parameters. Dramatically improved holding power and followability to stick operation. The highly rigid metal case and metal gears eliminate distortion due to repeated movements, thereby reducing motor power loss and contributing to longer life.

This product adjusts the control parameters assuming use at 7.4V or higher. Therefore, if you feel that the control is weak or the stoppage is poor when using at a low voltage, adjust the parameter value in the XBUS setting.
