Service and installation for EAGLE EX mixing arm

This replacement mixing arm is supplied as a control linkage component for the Hirobo EAGLE EX family. It sits between cyclic and collective inputs and the swashplate linkage, providing the mechanical joint used when installing or repairing rotor mixing geometry.

When fitting the mixing arm, inspect the mating pivots and linkages for free movement and minimal play before final assembly. Typical fitment involves aligning the arm with the swashplate and fastening it to the control link with the original hardware; keep any original washers or spacers to preserve the intended lever ratios and throw.

Small setup errors at installation can change collective-to-cyclic feel, so secure all fasteners, confirm link geometry, and perform a hover check at low power to verify correct movement before a full-power flight.

Compatibility

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

A straightforward service replacement for Eagle-series helicopters, useful when the original mixing arm shows wear or when performing fitment work on swashplate geometry.

Reuse the factory screws, washers, and spacers where possible to maintain correct lever ratios. If any hardware is damaged, replace like-for-like before flight testing.
Move the assembled linkage by hand to feel for binding or slop. Slight free movement is normal, but excessive side-to-side play means a worn pivot or missing spacer.
Start with low collective and small trims, then test stability at a low hover. Confirm swashplate movement is symmetric before increasing power.
