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

Precision locating pin for Hirobo helicopters

This HI2539030 guide pin is an RC-scale accessory intended for use within Hirobo helicopter general parts. It serves as a locating and alignment pin for small assemblies where accurate positioning reduces play and helps keep gears and rotor components aligned during setup and light tuning.

Compatibility is limited to general Hirobo helicopter components classified under pins and general parts, as indicated by the product category. Do not assume fitment to specific airframes or kits unless those parts explicitly reference HI2539030.

Installation is straightforward: seat the pin into the corresponding locating hole so mating parts sit squarely, then secure with the original fastener or retaining method used by the assembly. During installation check for lateral play and confirm that the pin does not bind rotating elements; the pin is intended to stabilise alignment rather than to carry heavy loads.

For tuning and maintenance, treat the guide pin as a wear item: inspect for bending, scoring, or corrosion when you service the helicopter, and replace the pin if it introduces play into the joint. Keeping mating holes clean and free of debris helps maintain accurate positioning.
