YS Engine YSS1037 Regulator Body B 50ST Replacement Housing for RC Engines  [YSS1037]

50ST Regulator Body B Replacement

This Regulator Body B is provided as a replacement component for YS 50ST regulator assemblies and related engine regulator mounts. It replaces the external housing and mounting interface but does not modify the regulator's internal tuning or operational setup.

To fit the new housing remove the old casing, transfer any internal components that are needed, align the replacement housing with the regulator's mounting points, and tighten using the original fasteners. Standard hobby hex drivers are normally adequate; inspect mating surfaces and any seals as part of the reassembly sequence.

As an RC engine spare, this item helps keep regulator placement and mounting geometry consistent after repair or wear, aiding serviceability and repeatable adjustments. Do not use this component outside model-scale applications.
