Hirobo HI0404504 TSURUGI SX blade holder, replacement part for TSURUGI SX helicopters  [HI0404504]

TSURUGI SX blade holder

This Hirobo HI0404504 blade holder is an RC-scale replacement part intended for TSURUGI SX series model helicopters. It serves as the rotor blade retention point on the main rotor head and is supplied as a single replacement unit for routine maintenance or part renewal.

Fitment and role: confirm that your airframe is a TSURUGI SX variant before replacing the blade holder, as the part is produced for that platform. The component's role is to secure the blade root to the rotor head, keeping blade pitch linkage alignment stable during pre-flight checks and tuning sessions.

Installation and tuning notes: remove power and follow safe bench procedures, then swap the old holder for the HI0404504 unit using the original fasteners and torque settings from your helicopter's manual. After installation, perform static balance and vibration checks, and verify blade tracking during low-throttle rotor spin to ensure flight-ready setup.
