Replacement Servo Housing for Compact JR Propo Servos

This servo case set is an RC-scale spare designed to match the mounting and footprint of the listed JR Propo servo models. It serves as a direct replacement housing to restore a damaged case or to secure a servo after maintenance, keeping alignment and gear mesh stable within the model-scale drivetrain.

Installation is intended for hobby-level workshop use, using common hand tools. Check the original servo screws and internal mounting posts for wear before transfer, and verify horn alignment and end-stop before reinstalling into the model. The part supports routine tuning tasks by ensuring the servo remains fixed under load and reducing play that can affect steering or throttle feel at scale.

Will this housing swap straight onto my listed JR Propo servo models?

The case is manufactured to align with the original footprint for the listed JR Propo models. When installing, compare screw hole positions and post heights to the old housing and transfer components carefully.

Do I need to tweak anything after fitting the new case?

After assembly, confirm the servo horn centers correctly and that full travel is unobstructed. Make minor trim or reindexing adjustments if there is any binding before putting the servo back into service.
