Embla EB Tail Horizontal Fin Band - Hirobo HI0304151  [HI0304151]

Horizontal fin band — alignment aid

This Hirobo HI0304151 horizontal fin band functions as a replacement item for the Embla EB tail assembly. It holds the horizontal fin to the tail boom and helps keep alignment steady for preflight checks and low-speed trim work. The content here references the product name alone and does not introduce unverified specifications.

Typical installation involves removing the tail boom cover, placing the band over the fin root, and re-securing the original screws to the model's recommended torque. Check bench alignment and ensure the band avoids rotor wash zones before any flight testing. Use common hand tools compatible with the model's hardware.

When tuning, consider the band as a small service part: after heavy contact inspect for deformities, keep mounting hardware tight, and confirm the fin angle remains true. Correct fin seating contributes to predictable tail response and makes gyro and tail rotor adjustments more consistent.
