Lepton Lex Tail Fin Set HI0304054 Replacement Hirobo  [HI0304054]

Lepton Lex replacement tail fin

This Hirobo HI0304054 tail fin set is offered as a direct replacement for Lepton Lex helicopters, shown by model to help hobbyists confirm correct fit before buying.

The set restores tailplane geometry that influences yaw stability and tail response, and is supplied to replace worn or damaged fins while enabling routine trim and tracking work.

Installation follows standard tail maintenance: remove the old fin from its mount, reuse suitable retained hardware where applicable, and align the new fin with the tail boom and vertical stabiliser. After installation, check tail tracking and make small trim tweaks until straight flight and controlled yaw are restored.

During tuning, a properly aligned fin contributes to steady tail authority and reduced flutter. Final behaviour is influenced by the rotorhead and tail control setup, so make incremental changes and verify hover trims before full-power testing.
