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

Technical details

The Futaba FU11K06401 drive plate is supplied as a direct replacement for the main gear/VR drive assembly in Futaba S9257, S9301, and S9304 servo models. Its primary function is to convey gearbox output to the servo horn while maintaining the VR drive coupling found on these variants.

Compatibility is confined to the listed Futaba models, so verify your servo model before ordering. Typical installation requires opening the servo case and transferring the internal gear stack; keep any original shims and bearings to ensure correct gear mesh and axial clearance. This component is intended solely for model servo repair and upkeep.

Use this drive plate when servicing to restore VR sensing engagement and replace worn mounting surfaces on the main gear. After completing the rebuild, confirm the servo centres, check horn alignment, and ensure smooth travel across the full range to prevent binding once reinstalled in the model.
