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

Carbon collective pitch lever for Eagle EX

This carbon collective pitch lever B is an RC-scale replacement part labelled HI0404732 from Hirobo, intended for use on Eagle EX rotor heads. Its role is mechanical: it transmits collective input from the swash/servo link to the rotor assembly and contributes to consistent pitch response when tuned and installed correctly.

When replacing the collective lever, check link geometry and bearing condition before fitting. Light carbon construction reduces rotating mass while maintaining torsional stiffness, which helps keep pitch movement crisp during aggressive cyclic and collective inputs. Use the original mounting hardware and inspect 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: small changes in lever spacing or ball link position affect pitch sensitivity more than gross head changes, so make incremental adjustments and recheck hover behavior before flight.
