Hirobo HI2506043 Plastic Flat Washer 6x22x1.3 — Helicopter Parts Upgrade  [HI2506043]

Spacer washer for model helicopter assemblies

This flat plastic washer is listed among helicopter general parts and matches the 6 x 22 x 1.3 mm identifier. It spreads bearing pressure over a wider area and helps preserve accurate clearances in tight component layouts.

Fitment notes: lay the washer flat on the mating surface, keep fastener threads and seating faces clean, and do not over-torque since compression will change the washer's effective thickness. Replace the washer if it becomes misshapen or shows surface failure.

Tuning role: the 1.3 mm thickness is handy for incremental adjustments to linkage geometry and preload, allowing fast, reversible tuning to address vibration or misalignment without part modification.
