This carbon A-side collective pitch lever is specified for Hirobo Eagle, Freya, EX and SX series helicopters. It functions as the A-side arm in the swash-to-rotor linkage and is supplied as a replacement or upgrade to retain accurate collective control.
Fitment follows the published parts lists for Eagle, Freya, EX and SX platforms, so this HI0404743 item is appropriate where an A-side carbon collective arm is listed. This product is an aftermarket replacement made for hobby helicopters rather than full-scale aircraft.
Installation advice: examine linkage pins and ball links for wear before fitting, orient the lever correctly relative to the swashplate and pitch links, and confirm full travel and servo endpoints after installation. Small tweaks to collective throw and dual-rate settings will help tune feel after fitting this carbon arm.
Service note: inspect the lever and mating hardware regularly after demanding flights, and swap any worn pins or links to keep collective behaviour predictable.
