Rudder Servo Alignment Spacer for Embla EB HI0304139 by Hirobo  [HI0304139]

Precision Spacer for Rudder Servo

This rudder servo spacer is designed specifically for the Embla EB tail assembly and carries the Hirobo model number HI0304139. It supplies a compact, accurate offset to correct servo alignment and axial spacing between the tail servo and the linkage while retaining the factory tail configuration on Embla EB machines.

Compatibility: intended for Embla EB series tail servo installations. Fit the spacer when the servo-to-tailframe gap requires a purpose-made shim to preserve straight linkage geometry. Do not fit to unrelated tail assemblies unless the mounting pattern and clearances are identical.

Installation notes: power down the model and secure the airframe before starting. Install the spacer between the servo case and the bulkhead or mounting bracket as needed to achieve correct linkage alignment. Use the original mounting hardware where possible and follow the same torque guidance; confirm full travel and adequate clearance prior to flight.

Tuning role: this item is a fitment accessory rather than a tuning part, intended to keep tail geometry neutral so that transmitter endpoint and trim adjustments produce consistent tail behaviour.
