HIROBO HI0404680 Mixing Arm for EAGLE EX Helicopter Control Link  [HI0404680]

Mixing arm for Eagle EX

This replacement mixing arm is intended as an RC-scale control linkage component for the Hirobo Eagle EX family. It functions at the junction between cyclic/collective inputs and the swashplate linkage, providing the mechanical interface used when setting up or repairing rotor mixing geometry.

When servicing the mixing arm, check the mating pivots and linkages for free movement and minimal slop prior to final installation. Fitment typically requires aligning the arm with the swashplate and securing it to the control link using the original hardware; retain any original washers or spacers to preserve intended lever ratios and throw.

For tuning, the mixing arm position affects collective-to-cyclic responsiveness and overall swashplate tilt. Small adjustments in arm position or swap of an alternate-length arm will change rates and feel at the swashplate, so make incremental changes and test hover stability before full-power runs.

Compatibility

• Eagle, Freya, EX, SX series common parts.

This part is a straightforward service item for Eagle-series helicopters, suitable for replacement or setup work where the original mixing arm is worn or when refining mixing geometry.
