Hirobo HI0304054 Lepton Lex tail fin set  [HI0304054]

Lepton Lex tail fin spare

This Hirobo HI0304054 tail fin set is a direct replacement accessory intended for Lepton Lex series RC helicopters. The listing identifies the part by model number and function so hobbyists can confirm fitment against their existing tail assembly before purchasing.

As a tail fin set, its role is focused on restoring or maintaining the tailplane geometry that affects yaw stability and tail response. It is supplied as a component set to replace worn or damaged fins and to support routine setup work such as trim and tracking adjustments.

Installation follows standard tail maintenance practice: remove the damaged fin from its mounting location, transfer any retained hardware where appropriate, and fit the new fin so that it's aligned with the tail boom and vertical stabiliser. After fitting, verify tail tracking and make small trim adjustments as needed to restore straight flight and predictable yaw behaviour.

When tuning, expect this part to contribute to consistent tail authority and reduced flutter when properly aligned and secured. Final tail behaviour depends on the overall rotorhead and tail control setup, so use incremental changes and test hover trims before full-power runs.
