Regulator Body A 50ST Replacement

This RC-scale regulator body is the YS Engine YSS1040 replacement for the S1036 regulator body, supplied as a direct-fit spare for regulator assemblies. It is intended to restore the original housing geometry and mounting points so internal regulator components remain correctly positioned during maintenance or setup.

Use this part when the original regulator body shows wear, damage, or when preparing an engine for bench tuning and routine service. The component is a like-for-like replacement for S1036 style assemblies, and no modification to the regulator assembly is generally required when the part is correctly aligned and secured.

Installation guidance: remove the regulator assembly from the engine model following standard disassembly practices, note orientation and fastener locations, swap the old body for the YSS1040 unit, and reinstall using the same mounting hardware. Verify clearances and linkage alignment before running the engine at increased settings.
