Hirobo EX Carbon Tail Pitch Lever Stay B HI0404748  [HI0404748]

Overview: Tail Pitch Lever Stay and Fitment

The Hirobo HI0404748 EX carbon tail pitch lever stay B is supplied as an RC-scale replacement for tail pitch linkage assemblies on EX series helicopters. It functions as the mounting and lever interface between the tail pitch control rod and the tail structure, useful during repairs or when tuning tail response.

Constructed from carbon, this component provides a lower-mass mounting option compared with heavier materials while maintaining the required stiffness for accurate linkage operation. Fit it to renew worn parts, re-establish correct linkage geometry, or when changing the tail servo-to-linkage configuration during setup sessions.

Fitment guidance: carefully remove the tail cover and original lever stay, move any salvageable bushings or bearings to the new stay, and tighten fasteners evenly without over-torquing to prevent damaging carbon sections. Once installed, confirm smooth movement through the linkage and remove any play before conducting flight checks.

Tuning note: although small, the lever stay affects tail control consistency. Replacing it helps ensure repeatable lever geometry while adjusting tail gain, endpoint settings, or other control parameters as part of routine maintenance.
