Hirobo HI0403209 Compatible Pitch Arm for SHUTTLE RG GPH 346  [HI0403209]

Shuttle RG GPH 346 pitch arm details

Sold under Hirobo part number HI0403209, this replacement pitch arm is intended for the SHUTTLE RG GPH 346 pitch assembly. It is supplied as a direct service component for repair and routine maintenance tasks.

The arm acts as the mechanical link that moves collective and cyclic blade angles in response to servo input. Check ball link seating, control horn clearance, and ensure there is no binding before the first flight, and torque any reused hardware to the chassis maker's specs.

Replacing worn pitch arms often restores original stick-to-blade response. Match the replacement's geometry to the part removed to avoid changing servo throw or blade angles unintentionally, and apply threadlocker to metal fasteners when recommended by the maintenance guide.
