EAGLE EX Replacement Mixing Arm HI0404680 Durable Control Link HIROBO  [HI0404680]

Durability and wear guidance for the EAGLE EX mixing arm

This replacement mixing arm is designed as a control linkage part for the Hirobo EAGLE EX series, providing the mechanical connection between cyclic/collective inputs and the swashplate. It is intended for refurbishment and service scenarios where reliable pivot action is required.

When replacing the arm, inspect pivots and link joints for wear and free movement before final assembly. Install by aligning the arm with the swashplate and securing with the original fasteners; preserving any original washers or spacers helps keep the correct lever ratios and travel limits.

Worn or loose mixing arms will change collective-to-cyclic response and can affect swashplate tilt. Check the linkage during routine maintenance and replace the arm if you detect excess play, then verify trim and hover stability after installation.

Compatibility

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

A practical replacement component for Eagle-series helicopters, suitable when the original arm shows wear or when restoring proper mixing geometry and control response.
