Eagle EX Replacement Carbon Collective Lever B HI0404732 by HIROBO  [HI0404732]

Compatibility checks for fitting the Eagle EX collective lever

This carbon collective pitch lever B, part number HI0404732 from HIROBO, is intended for Eagle EX rotor heads. It transfers collective input from the swash/servo link to the rotor assembly and helps keep pitch response consistent when matched and installed correctly.

When replacing the lever, check link geometry and bearing condition prior to fitting. The light carbon construction reduces rotating inertia while maintaining torsional stiffness, supporting crisp pitch changes under aggressive control inputs. Use the original mounting hardware where possible and examine retaining pins and ball links for any 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: small alterations in lever spacing or ball link position affect pitch sensitivity more than broad head changes, so adjust gradually and check hover characteristics after each change.
