Lepton Lex Tail Fin HI0304054 Replacement Component Hirobo  [HI0304054]

Replacement fin for Lepton Lex models

This Hirobo HI0304054 tail fin set is a replacement accessory for Lepton Lex helicopters and is identified by model number so owners can confirm fitment prior to purchase.

The fin set helps re-establish tailplane geometry that governs yaw stability and control response. It arrives as a component set to swap out deteriorated fins and to support standard trim and tracking procedures.

Fit the new fin by removing the damaged unit, transferring any sound mounting parts, and seating the replacement so it is aligned with the boom and vertical stabiliser. Once mounted, inspect tail tracking and make small trim changes until flight becomes stable and predictable.

When tuning, expect improved tail authority and less chance of flutter if the fin is secure and aligned. Remember that overall tail characteristics are influenced by rotorhead settings and control linkages, so proceed with conservative adjustments and hover testing.
