Hirobo HI0304151 Horizontal Fin Band for Embla EB tail assembly  [HI0304151]

Horizontal fin band — tail component

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 typically involves removing the tail boom access panel, seating the band around the fin root, and re-tightening the existing fasteners to the aircraft's original torque. Check fin alignment on the bench before flight, and verify that the band does not contact the rotor wash or other moving parts. Use basic hand tools compatible with the model's fasteners and confirm clearances after installation.

For tuning and maintenance, treat the part as a small-scale replacement: inspect for cracks or deformation after hard landings, ensure mounting screws remain secure, and confirm the fin angle remains true relative to the tail boom. Proper seating and alignment of the horizontal fin contributes to predictable tail behaviour and makes follow-up adjustments to the tail rotor and gyro setup more consistent.
