Hirobo HI0304054 Lepton Lex Tail Fin Set  [HI0304054]

Tailplane fin for Lepton Lex

The Hirobo HI0304054 tail fin set fits Lepton Lex helicopters and is listed by model number so pilots can verify compatibility with their airframe before ordering.

This component set is intended to maintain or restore the tailplane geometry that affects yaw control and response. It replaces damaged or aged fins and supports routine adjustments like trim and tracking.

To install, remove the damaged fin and transfer any usable mounting hardware, then align the replacement with the tail boom and vertical stabiliser. After fitting, confirm tail tracking and make small trim changes to bring the model back to straight, predictable flight.

In tuning, the fin assists in delivering consistent tail authority and lowering the chance of flutter when correctly installed. Overall tail behaviour will still depend on rotorhead tuning and tail control settings, so proceed with gradual adjustments and hover checks.
