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

Flat washer for RC helicopters

This flat washer is an RC-scale plastic component listed under helicopter general parts, specified as 6 x 22 x 1.3 mm in the product identifier. It serves as a thin, load-spreading spacer typically placed between fasteners and mating surfaces to reduce bearing stress and help maintain consistent gaps in tight helicopter assemblies.

Installation notes: seat the washer flat on the mating surface, ensure surrounding parts and fasteners are clean, and avoid over-torquing which can compress plastic washers and alter spacing. For routine maintenance check the washer for deformation or wear and replace if its flatness or thickness no longer provides the intended spacing or load distribution.

Tuning role: when trimming vibration or adjusting linkage geometry, a washer of this thickness can be used to fine-tune clearances without modifying components, allowing small incremental changes to alignment and preload in housings, bearing seats, and bolted joints.
