Futaba S3401/S9404 Replacement Servo Case Set - FUAS3097 EBS3221  [FUAS3097]

Replacement shell for S3401 and S9404

This servo case set is an accessory referenced by Futaba FUAS3097 and part code EBS3221, intended for use with Futaba S3401 and S9404 radio-control servos. It is supplied without original retail packing and serves as a replacement outer housing for routine maintenance or repair work on model servos.

Use this case set when replacing a damaged outer shell or when preparing a spare set for track-side or field service. The set supports common service tasks: removal of the old case, careful transfer of internal gears and electronics, and final reassembly. It is sold as a component-level housing rather than a complete servo unit.

Installation notes: perform work in a clean area, keep small screws and parts organised, and mark gear orientation before disassembly. This housing helps speed up repairs by allowing quick replacement of the external shell without sourcing a full new servo.

Role in setup and tuning: the case itself does not alter servo output, but having spare housings reduces downtime after crashes and makes serviced servos available sooner during setup cycles.
