HI2539030 M2.6 x 5 Hirobo Guide Pin for General Helicopter Parts  [HI2539030]

Hirobo helicopter guide pin overview

This HI2539030 guide pin is an RC accessory intended for Hirobo helicopter general parts. It acts as a locating and alignment pin for compact subassemblies, helping to maintain correct relationship between gears and rotor components during routine setup and tuning.

Intended compatibility is with general Hirobo components categorized under pins and general parts. Do not presume compatibility with specific airframes unless those parts explicitly list HI2539030.

Installation is direct: insert the pin into the corresponding locating hole so mating components seat squarely, then fasten using the assembly's original securing method. After fitting, verify there is no lateral play and that rotating elements move freely without binding.

For maintenance and tuning, treat the guide pin as a replaceable item: inspect for bends, scoring, or corrosion during service and swap it if it causes play. Keeping mating holes clear of debris helps preserve correct alignment.
