Futaba S9257 S9301 S9304 Servo Main Gear VR Drive Plate FU11K06401  [FU11K06401]

Overview and fitment

This Futaba FU11K06401 drive plate is a direct replacement component intended for the main gear/VR drive assembly used in Futaba S9257, S9301, and S9304 servo models. The item transfers output motion from the servo gearbox to the horn while preserving the VR drive interface specific to these servo variants.

Fitment is restricted to the listed Futaba models, so confirm your servo model before ordering. Installation is a swap inside the servo output stack and generally requires removal of the servo case and careful transfer of the internal gear stack; keep original shims and bearings to maintain correct gear mesh and endplay. This item is an accessory for scale RC servos only.

For maintenance and tuning, the drive plate restores VR sensing engagement and renews worn main gear mounting points. After reassembly, verify servo centring, horn alignment, and smooth travel through the entire range to prevent binding before putting the servo back into service.
