Futaba FUAS4098 S9072SB S9451 Servo Case Set  [FUAS4098]

Servo case set for listed Futaba servos

This servo case set is an RC-scale replacement shell intended for the Futaba model codes listed in the product name. Use it to renew damaged outer housings or to restore fitment when a servo has been disassembled for maintenance.

Designed as a direct housing replacement, the set allows reuse of the original internal gearbox, PCB and motor while providing a new mounting interface and exterior finish. When replacing the shell, take care to preserve gear alignment and brushless/coreless motor clearance where applicable, and confirm the spline and mounting flange match the original parts before final assembly.

Practical tuning role: swapping the outer case does not change the servo’s electrical performance, but it can affect mounting tolerances and clearance inside model bays, so verify servo travel and horn seating after reassembly.
