Hirobo HI2506063 Flat Washer 4x7x1T  [HI2506063]

Flat washer for RC helicopters

This Hirobo HI2506063 flat washer is an RC-scale accessory intended for use in helicopter maintenance and assembly tasks. The part is identified by its 4x7x1T designation which denotes its nominal inner diameter, outer diameter, and thickness as listed by the manufacturer name and model number.

Use cases include acting as a thin spacer or load-distributing washer in rotor linkages, frame joints, and other fastener locations where precise spacing helps maintain alignment. The washer's role in tuning is to manage play and ensure consistent contact between mating parts without changing the core geometry of components.

Installation advice: confirm fit on the target bolt or shaft and check clearance within the surrounding hardware before final assembly, the washer should sit flat and not introduce bending on fasteners. Replace if deformed or excessively worn to maintain reliable fastener performance in RC helicopter systems.
