This RC-scale replacement part is the main gear stopper specified for the Sceadu SD series, engineered to hold the main gear assembly steady during setup and routine maintenance. Its retention and positioning function keeps the gear located while you adjust meshing or service the transmission on Sceadu SD helicopters.
Installation is straightforward: remove the main gear cover to access the gear seat, place the stopper into the designated mounting point on the Sceadu SD main assembly, then check axial alignment and clearance before reassembly. Follow standard RC hardware practice when tightening fasteners and confirm the gear train rotates freely by hand after installation.
During tuning and rotorhead adjustments the stopper enables repeatable mesh checks and temporary locking so you can fine tune drivetrain engagement. It is supplied as an RC hobby replacement part and should be fitted only to compatible Sceadu SD airframes where the original component is specified.
