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

Durability and material benefits for Eagle EX installations

This carbon collective pitch lever B is supplied as part HI0404732 from HIROBO and intended for use on Eagle EX rotor heads. Its mechanical duty is to pass collective commands from the swash and servo link to the rotor, contributing to steady pitch response when installed and tuned properly.

When replacing the lever, inspect link geometry and bearing condition ahead of fitting. The carbon construction trims rotating mass while preserving torsional rigidity, which supports precise pitch movement under demanding flight inputs. Retaining the original mounting hardware is recommended and all pins and ball links should be checked for wear before reuse.

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: minor changes to lever spacing or ball link position will shift pitch sensitivity more than bigger head changes; make incremental moves and reassess hover performance.
