Lepton Lex Horizontal Fin Band Mount - Hirobo HI0304053  [HI0304053]

Tailplane band for Lepton Lex frames

This Hirobo replacement part is an RC-scale horizontal fin band manufactured to suit Lepton Lex series layouts. It functions as the mounting element for the horizontal stabiliser assembly on compatible Lepton Lex airframes, focusing on tailplane placement and alignment rather than altering control geometry.

The band is intended where a separate horizontal fin support is needed; installers should check fitment against the Lepton Lex fin mount points and ensure the part sits flush with the tailboom and stabiliser surfaces. During fitting, confirm the fin is straight in the neutral position and that linkages move freely through their range without binding.

For trim work, this component helps preserve stabiliser position after tail pitch or rotor adjustments. It acts mainly as a mechanical locator and retention piece, aiding repeatable setups and quick replacement during routine maintenance.
