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

Technical overview

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 serves the specific role of transferring output motion from the servo gearbox to the horn while retaining the VR drive interface used by these servo variants.

Compatibility is limited to the listed Futaba models, so verify your servo model before ordering. Installation is a component swap within the servo output stack, typically requiring removal of the servo case and careful transfer of the internal gear stack; retain original shims and bearings where present to preserve gear mesh and endplay. This product is an RC-scale accessory and intended only for model servos.

For tuning and maintenance, use this drive plate to restore proper VR sensing engagement and to replace worn main gear mounting points. After reassembly, check servo centring, horn alignment, and free movement through the travel range to avoid binding before reinstalling in the model.
