Hirobo HI0304021 Lepton SZM Slide Block  [HI0304021]

Lepton SZM slide block details

This is an RC-scale replacement slide block listed as HI0304021 for the Hirobo Lepton SZM rotor head. The part is intended to interface with the slide mechanism in the rotor assembly and serves as a direct replacement for the original slide block design.

Functionally, the slide block locates and guides the sliding elements that control pitch and cyclic linkage geometry; correct fit reduces lateral play and helps maintain predictable servo-to-rotor response. Inspect the mating surfaces and linkage clearance when installing to ensure smooth movement without binding.

Installation notes: fit the block into the rotor head slot and secure using the original hardware, checking for free travel across the full blade pitch range. After installation, verify linkage geometry and control throws before flight, and re-check for any unwanted axial or lateral play as part of routine maintenance.
