This Hirobo HI0402313 Tail Pitch Lever Set is supplied as a replacement component for S-30 tail assemblies and restores the linkage that conveys servo motion to the tail rotor pitch mechanism. It is intended for use when original levers exhibit wear, looseness, or have been damaged.
Fitting involves removing the tail boom access panel, freeing the old lever from the pitch link and pushrod, and securing the replacement lever to the same mounting points while ensuring correct orientation and unimpeded movement. After fitting, check servo travel and neutral to prevent a biased pitch condition.
As a maintenance item the lever preserves the intended kinematic relationship between the tail servo and rotor pitch control rather than acting as a tuning upgrade. Regular inspection of fasteners and linkages will help keep tail behaviour stable.
