Futaba FUAS3273 Servo Housing Compatible with S3117 S3157  [FUAS3273]

Product Summary: Futaba FUAS3273 Servo Housing

The Futaba FUAS3273 servo case set is a replacement shell for Futaba S3117 and S3157 servos and references the original codes AS3273 and EBS3357. It is supplied without retail packing and serves as a direct housing replacement for hobby servo repairs.

The replacement case supplies the structural enclosure and mounting interfaces that hold the control electronics and gearbox in place. Fitting a replacement housing restores the original footprint so the servo installs correctly in radio trays and lines up with the output horn.

Installation is suitable for those experienced with servo servicing: remove the servo from the model, disconnect any wiring if necessary, separate the old case with the appropriate hex driver, transplant the internals into the new case, check gear mesh and travel limits, then reassemble and bench-test prior to refit. No specialist equipment beyond standard servo tools is required.

This case set is intended for repairing damaged housings, modifying mounting options, or preparing servos for bench calibration; it is designed exclusively for hobby RC use and not for full-size vehicle applications.
