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

Tuning impact of the carbon collective lever on pitch feel

This carbon collective pitch lever B carries the HI0404732 identifier from HIROBO and is designed for Eagle EX rotor heads. Its function is purely mechanical: transferring collective input from the swash and servo link into rotor pitch changes, helping achieve a steady response when correctly set up.

Before fitting, verify link geometry and bearing condition. The lighter carbon profile lowers rotating mass while keeping torsional stiffness, which refines pitch transitions during aggressive cyclic and collective inputs. Always inspect and, where appropriate, reuse original mounting screws and check retaining pins and ball links for 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: tiny adjustments in lever spacing or ball link position can significantly change pitch sensitivity, so tune in small increments and test hover behavior between changes.
