Eagle EX Carbon Collective Pitch Lever B - HI0404732 by HIROBO  [HI0404732]

Installation guide for the Eagle EX carbon collective lever

This carbon collective pitch lever B is an RC replacement part labeled HI0404732 from HIROBO, made for Eagle EX rotor heads. It transmits collective movement from the swash and servo link to the rotor assembly and helps preserve consistent pitch response when correctly fitted and adjusted.

Before replacing the collective lever, confirm link geometry and check bearings for play. The light carbon construction lowers rotating mass while keeping torsional stiffness, helping maintain a crisp pitch response during firm cyclic and collective inputs. Reuse original mounting hardware where possible and inspect retaining pins and ball links for any signs of wear.

Installation notes:

• Remove and retain any original spacers and screws to preserve head geometry.
• Confirm lever orientation matches the servo arm and swashplate alignment before tightening.
• After installation, verify pitch neutral and end points with transmitter trims and mechanical link adjustments.

Practical tuning tip: when setting up, make only small adjustments to lever spacing or ball link position because these changes affect pitch sensitivity more than larger head modifications. Recheck hover stability after each tweak.
