Futaba S9404 Aerobatic Coreless Servo - High Speed  [S9404]

Accurate Inputs from the Futaba S9404

The Futaba S9404 offers a combination of fast response and steady torque for critical control roles. Removing the typical magnet assembly in favour of a coreless motor gives a cleaner, more reliable motion profile.

Benefits of a Coreless Motor

With the Futaba S9404, the coreless motor design helps reduce uneven torque peaks and improves consistency across repeated movements. That makes fine corrections feel more natural and predictable.

Ideal for 3D and Aerobatic Use

When rapid throws and precise centring are needed, the Futaba S9404 performs well as a rudder or elevator servo in aerobatic and 3D models, supporting sharp manoeuvres and tight routines.
