XRAY RX8 7075 Pulley Collar Upgrade for RX8 - Arrowmax AM-RX8-345800  [AM-RX8-345800]

About the 7075 pulley covers for RX8

Arrowmax AM-RX8-345800 supplies a 7075 aluminium pulley cover set as an RC-scale swap for the XRAY RX8 kit plastic collars. The machined aluminium parts increase rigidity where the pulley mounts, helping to preserve belt tracking during setup changes and under load.

These covers are designed to fit the RX8 kit arrangement and take the place of the standard plastic pieces without altering the gearbox layout. Installation involves removing components around the rear pulley and reusing the original fasteners where applicable, then checking pulley runout post installation.

In practice, the aluminium covers give firmer shaft support which can reduce small amounts of belt deflection and make belt tension settings more repeatable. They are a practical, long lasting upgrade for hobbyists who prefer metal over plastic for these collars.
