Hirobo HI0404748 EX carbon tail pitch lever stay B - carbon tail pitch linkage part  [HI0404748]

Tail pitch linkage part overview

This HIROBO HI0404748 EX carbon tail pitch lever stay B is an RC-scale replacement part for tail pitch linkage assemblies on EX series helicopters. It serves as the mounting and lever interface between the tail pitch control rod and the tail assembly, intended for use during repairs or targeted tuning of tail response.

Manufactured in carbon material as indicated by the product name, the component is intended to provide a lightweight mounting option for the tail pitch lever. Use it to replace worn parts, to restore correct linkage geometry, or when reconfiguring the tail servo-to-linkage connection during setup.

Installation notes: remove the tail assembly cover and existing lever stay, transfer any required hardware such as bushings or bearings from the original part, and secure the replacement without overtightening fasteners to avoid deforming carbon sections. After installation, check for smooth free travel and adjust the tail pitch linkage to eliminate play before flight testing.

Role in tuning: the lever stay is a small but critical element in tail control precision. Swapping it during tuning sessions can help ensure consistent lever geometry when testing tail gain or servo endpoints, and it is commonly used as part of routine maintenance on RC helicopters.
