EAGLE EX Swashplate Mixing Arm - Tuning Link HI0404680 by HIROBO  [HI0404680]

How the mixing arm alters swashplate behaviour on EAGLE EX

This replacement mixing arm serves as the mechanical link in the Hirobo EAGLE EX lineup, transferring cyclic and collective inputs to the swashplate. Its purpose is to let you set or restore the rotor mixing geometry with predictable pivot action.

Before finalising installation, verify that all pivots and link points move freely and have minimal slop. Align the arm to the swashplate and secure it with the original fixing hardware, retaining washers and spacers to preserve the intended leverage and travel.

For tuning, small shifts in arm position or swapping to a different length will alter the collective-to-cyclic ratio and the swashplate tilt. Make measured adjustments, test hover response, and re-trim after each change to dial in the handling you want.
