The HI0404136 EX-2 slide block by Hirobo is intended as a direct replacement component within helicopter cyclic link assemblies. It provides a controlled sliding surface that helps keep linkage motion smooth and predictable under normal flight loads.
Recorded as a common spare for Eagle, Freya, EX and SX series airframes, this part should be confirmed against your model's parts breakdown before purchase. It is provided as a single unit and intended for hobby use only.
Fitting advice: remove the affected linkage and check mating pins, bushes and bearings for signs of wear. Install the slide block ensuring free, unconstrained travel and do not over-tighten securing hardware. After refit, cycle the controls by hand and verify full throws via your transmitter and servos prior to flight.
Replace worn linkage slides with the HI0404136 to reestablish correct cyclic motion, and always bench-check alignment and travel before flying.
