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

Replacement horizontal fin band

This Hirobo HI0304151 horizontal fin band is an RC-scale replacement component intended for the Embla EB tail assembly. Its role is to secure the horizontal fin to the tail boom and keep alignment consistent during preflight checks and low-speed tuning. The description here references the product name only and does not add unverified specifications.

Installation commonly involves removing the tail boom access panel, seating the band around the fin root, and re-tightening the original fasteners to the aircraft's specified torque. Verify fin alignment on the bench before flight and confirm the band clears rotor wash and other moving parts. Use standard hand tools that match the model's fasteners and inspect clearances after fitting.

For routine maintenance treat this as a small-scale replacement: inspect for cracks or deformation following hard landings, ensure mounting screws remain secure, and check that the fin angle stays true relative to the tail boom. Proper seating and alignment of the horizontal fin helps deliver predictable tail behaviour and eases follow-up adjustments to the tail rotor and gyro setup.
