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

Tail Lever Stay: Purpose and Use

The Hirobo HI0404748 EX carbon tail pitch lever stay B is supplied as a replacement for the tail pitch linkage assembly on EX series helicopters. It serves as the lever mount between the tail pitch control rod and the tail structure, intended for repair work or precise tuning of tail behaviour.

Being a carbon part, it offers a lightweight mounting solution that preserves alignment and resists flex under normal loads. Replace worn components with this stay to restore correct linkage geometry or to alter the tail servo-to-linkage arrangement during setup changes.

Fitting advice: remove the tail cover and existing lever stay, carry over any reusable bushings or bearings, and secure the new stay without over-tightening to protect the carbon. After installation, check the linkage for smooth operation and remove any endplay before attempting flight.

Effects on setup: although small, the lever stay impacts repeatability of tail geometry. Swapping it can ensure consistent lever positions during testing of tail gain, servo travel, or flybarless tuning routines, and is a common service item for RC helicopters.
