Hirobo HI0304053 horizontal fin band for Lepton Lex horizontal fin assembly  [HI0304053]

Horizontal fin band for Lepton Lex

This Hirobo replacement part is an RC-scale horizontal fin band designed from the product name to suit Lepton Lex series layouts. It serves as a dedicated mounting element for the horizontal stabiliser assembly on compatible Lepton Lex airframes, providing a focused role in tailplane placement and alignment rather than changing control geometry.

The band is used where a discrete horizontal fin support is required; installers should verify fit against the Lepton Lex fin mount points and confirm that the part seats flush with the tailboom and stabiliser surfaces. During installation check that the fin sits straight in the neutral position and that any linkages are free to move across the intended travel range without binding.

For tuning, this component helps maintain consistent stabiliser positioning after adjustments to tail pitch or rotor trim. It is primarily a mechanical location and retention item, so its impact is on repeatability of setup and ease of swapping replacement parts during maintenance.
