This is an RC-scale replacement case set for Futaba S5801 class servos, supplied without retail packing. The set provides the external housing components used to enclose the servo internals and secure the output shaft and mounting tabs.
Intended use is maintenance and field repairs where a damaged shell needs replacement, or when transferring internal electronics and gears into a fresh housing during workshop tuning. The parts are designed to accept the original S5801 internal assembly without modification.
Installation involves removing the original case screws, transferring the PCB, gears, and output horn into the new shell, and reassembling with the matching fasteners. Check alignment of the output spline and horn before final tightening to preserve neutral centring during bench setup.
