BLS151 BLS171HV BLS171SV Protective Servo Case for Futaba - FUEBS3368  [FUEBS3368]

Replacement housing for Futaba BLS servos

The Futaba FUEBS3368 servo case set is an aftermarket replacement housing intended to protect the Futaba servo models shown in the title. It provides a snug fit to limit unwanted motion that can introduce steering or control surface inconsistencies.

This case is compatible only with the listed Futaba models: BLS151, BLS171HV, and BLS171SV. Check that the servo horn orientation and the spacing of the mounting screw holes match the case openings to ensure correct positioning before final assembly.

Fitting notes: take off the servo horn and unplug any linkages, slide the servo into the case so splines and screw holes align, then use the servo's original screws with controlled torque. Inspect travel and horn alignment again before reconnecting any linkages.

Performance note: using a dedicated case helps maintain a consistent servo location inside the model, which can cut down on play and make trimming more predictable. It also assists with neat cable routing away from moving parts.
