Regulator Body B 50ST

This replacement Regulator Body B is an RC-scale spare part intended for use with YS 50ST regulator assemblies and related engine regulator mounts. It serves as a direct-fit replacement piece that restores the external housing and mounting interface of the regulator assembly without altering the regulator's internal tuning or performance.

Installation is straightforward for hobby technicians familiar with RC engine service: remove the affected regulator housing, transfer any internal components as required, align the housing to the regulator assembly mounting points, and secure with the original fasteners. No special tools beyond common hobby hex drivers are required for basic swap-out, but inspect mating surfaces and seals during reassembly.

In practical tuning and maintenance workflows this part helps maintain consistent regulator placement and mounting geometry after repair or wear, supporting repeatable adjustments and easier troubleshooting. Treat the item as an RC engine spare part and avoid use outside model-scale applications.
