Hirobo HI2521099 Collar 2 x 6 x 6 F7.3 x 0.5 for Small Rotorcraft  [HI2521099]

Durable collar for small rotorcraft

This small collar is offered as a Hirobo general part, listed with model HI2521099 and measurements 2 x 6 x 6 F7.3 x 0.5. It is suitable for small-scale RC helicopter builds where a compact collar is needed to position or retain rotating or sliding elements on shafts.

Compatibility guidance: shown under Hirobo helicopter general parts, the collar is appropriate for Hirobo rotorcraft collections and other mini RC helicopter assemblies that accept matching collar dimensions. Check the shaft diameter and surrounding components before final assembly.

Maintenance advice: ensure correct seating and alignment on the shaft, and secure with the intended fastener type for your machine. By limiting axial play, small collars help maintain spacing between moving parts and can reduce wear in blade linkages when inspected regularly.
