Hirobo HI0414533 mixing arm SSZ-IV for Eagle Freya helicopters  [HI0414533]

Mixing arm for Eagle Freya

The Hirobo HI0414533 SSZ-IV mixing arm is an RC-scale replacement part intended for use with Eagle Freya series helicopters. It serves as a direct component in the rotor mixing link system, transferring motion between control linkages and the mixing mechanism. The description and numbering indicate the SSZ-IV variant without implying additional materials or altered geometry beyond the original part code.

Installation is straightforward for experienced hobbyists: remove the existing mixing arm, align the replacement to the original mounting points, and fasten using the vehicle's original hardware while verifying free movement through the full collective and cyclic range. Confirm the part number and visual fit against the removed component before final installation to ensure correct fitment.

In tuning and setup, the mixing arm functions as part of the mechanical chain that sets mixing ratios between swashplate inputs and tail or cyclic outcomes; small differences in arm length or mounting position affect control response, so re-check trim and endpoint settings after replacement and perform hover tests before full flight.

This part is presented as a like-for-like replacement for the SSZ-IV mixing arm on Eagle Freya helicopters, intended for hobby-scale rotorcraft maintenance and tuning where maintaining original part numbering is required.
