This is an RC-scale one way hub designed for Kyosho FW05-R and FW05RR applications, produced by 3Racing as part number FW05-010. The component uses aluminum to increase rigidity compared with softer materials, and serves as a direct replacement option where a one way hub is required on the FW05 series.
Functionally, the part affects how the driven wheel decouples under certain throttle and cornering inputs, providing a firmer engagement profile useful when adjusting differential behavior and traction transitions. It is intended for hobby use on model chassis and should be handled as a scale accessory only.
Installation notes: the hub is intended to follow OEM fit dimensions for the FW05-R/FW05RR hubs. Confirm compatibility with your existing hub carriers and fasteners before installation, and inspect fitment after first run to verify engagement and clearance.
Use this aluminum one way hub when you want a firmer mechanical response from the one-way assembly on Kyosho FW05-R and FW05RR chassis; verify fit and perform routine checks after fitting.
