Replacement Pitch Arm HI0403209 for SHUTTLE RG GPH 346 - Hirobo  [HI0403209]

Service pitch arm compatible with SHUTTLE RG GPH 346

This RC-scale pitch arm carries the Hirobo part number HI0403209 and is intended for the SHUTTLE RG GPH 346 pitch assembly. It is offered as a maintenance item to preserve correct pitch link function during part swaps or setup updates.

The component transmits servo motion into collective and cyclic adjustments. Inspect fitment and ball link engagement before flying, make sure control horns move freely without binding, and follow your airframe supplier's torque recommendations when reusing original fasteners.

Replacing a fatigued arm can improve stick-to-blade tracking. Check the new arm's geometry against the original to prevent unintended changes to servo throw and blade angle, and apply threadlocker on metal threads where the service manual advises.
