Hirobo HI2506043 6x22x1.3 Plastic Flat Washer for RC Helicopter Parts  [HI2506043]

Flat spacer for RC helicopter assemblies

This plastic flat washer is listed as a helicopter general part and matches the 6 x 22 x 1.3 mm size shown in the product identifier. It functions as a thin spacer to spread bearing loads and preserve precise gaps inside tight helicopter assemblies.

Installation notes: seat the washer flat on the mating surface, keep surrounding fasteners and contact areas clean, and avoid over-torquing which can compress plastic washers and change spacing. Inspect periodically and replace if the washer shows flattening, cracking, or loss of thickness.

Tuning role: a 1.3 mm washer can be used to make small, reversible adjustments to linkage geometry and preload, helping to reduce vibration and fine-tune alignment without modifying other components.
