YS Engine YSS1040 Replacement Regulator Body A 50ST for S1036-style Assemblies  [YSS1040]

Body A 50ST Replacement Overview

This RC-scale regulator body is the YS Engine YSS1040 alternative to the S1036 regulator body, supplied as a direct-fit spare for regulator assemblies. It restores the original housing form and mounting points so internal components remain properly positioned during maintenance or setup operations.

Install this part when the existing regulator body shows wear or damage, or when conducting bench tuning and routine servicing. The component functions as a like-for-like replacement for S1036-type assemblies, and no special modifications are normally required if the part is fitted and aligned correctly.

Installation guidance: remove the regulator assembly from the engine using standard disassembly procedures, note the orientation and fastener locations, swap the old body for the YSS1040, and reinstall using the original hardware. Check clearances and linkage alignment before operating at higher settings.
