Hirobo HI0304139 EMBLA EB Rudder Servo Spacer  [HI0304139]

Rudder Servo Spacer for Embla EB

This is an RC-scale rudder servo spacer intended for use with the Embla EB tail assembly, identified by Hirobo model HI0304139. The spacer provides a compact way to correct servo alignment and axial spacing between the tail servo and tail linkage when fitting the factory tail layout on Embla EB models.

Compatibility: the part name indicates fitment for Embla EB series tail servo installations, use the spacer where the servo-to-tailframe gap requires a dedicated shim to maintain straight linkage geometry. Do not substitute this part for unrelated tail assemblies unless mounting points and clearances match.

Installation notes: remove power from the model and secure the airframe, then fit the spacer between the servo bulkhead or mounting bracket and the servo case as required to obtain correct linkage alignment. Fasten using the same mounting hardware and torque considerations used for the original servo mount, and verify full travel and clearance before flight.

Tuning role: this spacer is a fitment accessory rather than a tuning component by itself, its function is to help maintain neutral tail alignment and consistent geometry so that endpoint and trim adjustments on the transmitter yield predictable tail response.
