TSURUGI SX Main Blade Retainer - HI0404504 Replacement by Hirobo  [HI0404504]

TSURUGI SX Rotor Blade Holder Description

The Hirobo HI0404504 blade holder is an RC replacement item made for TSURUGI SX series helicopters. It serves as the mounting point that retains each main rotor blade at the rotor head and is sold as a single service part for maintenance tasks.

Fitment and role: ensure your airframe is a TSURUGI SX variant prior to fitting, since this holder is intended for that platform. The component secures the blade root and aids in keeping the blade pitch linkage correctly aligned during setup and checks.

Installation and tuning notes: remove all power and observe bench safety, then replace the old holder with the HI0404504 using the existing screws and the torque settings recommended in your service documentation. After replacement, perform static balance, vibration checks, and low-speed blade tracking verification to confirm flight readiness.
