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

Overview of the FUEBS3368 protective case

The Futaba FUEBS3368 servo case set serves as a replacement housing to protect and stabilise the Futaba servo models named in the product title. It is intended to reduce unwanted play and protect the unit within tight model compartments.

Compatibility is limited to the specific Futaba models listed: BLS151, BLS171HV, and BLS171SV. During planning, verify the servo horn direction and the mounting screw pattern match the case openings so the unit mounts correctly on final assembly.

Fitting advice: remove the servo horn and any connected linkages, seat the servo into the case ensuring splines and screw holes align, then secure with the servo's original screws using moderate torque to avoid damaging threads. Once fitted, re-check travel and horn alignment before refitting linkages.

Why use a case: a dedicated enclosure keeps the servo position consistent which reduces play and helps with repeatable trimming of steering and control surfaces. It also makes it easier to route and protect servo wiring from moving parts.
