EX Series Tail Pitch Lever Stay B - HI0404748 by Hirobo  [HI0404748]

Tail Pitch Lever Stay — Function and Fit

This Hirobo HI0404748 EX carbon tail pitch lever stay B is a precision replacement part for the tail pitch linkage on EX series helicopters. It provides the mounting interface between the tail pitch control rod and the tail assembly, intended for repairs or fine-tuning of tail response.

Made from carbon as indicated in the product name, the piece offers a lightweight option that helps keep linkage mass low while maintaining alignment. Use it to replace worn components, restore correct geometry, or reconfigure the tail servo-to-linkage connection during setup.

Installation notes: remove the tail assembly cover and the existing lever stay, transfer serviceable hardware such as bushings or bearings from the original part, and secure the replacement without overtightening fasteners to avoid crushing carbon sections. After fitting, verify smooth free travel and set tail pitch linkage to remove any play before a hover test.

Impact on tuning: the lever stay is a small but important element in tail control accuracy. Replacing it during tuning helps preserve consistent lever geometry when testing tail gain, servo endpoints, or flybarless settings, and it is a common item in routine helicopter maintenance.
