The aluminium ULTRA-LIGHT pinion is a dedicated RC motor pinion produced to reduce rotating mass while retaining strength by using hard coated 7075 T6 aluminium. It is machined on a specialised gear machine to produce precise tooth profiles and true running, which helps decrease drivetrain vibration when paired with a matching spur gear.
Service-friendly features include fine internal threading for reliable mounting, etched tooth-count marking for easy identification, and a hard coating that increases wear resistance without adding notable weight. The specification "20T / 64" clarifies the tooth count and pitch reference used for selection and matching.
When tuning, this pinion is intended to cut motor inertia for better throttle responsiveness and lower rotating losses while maintaining the dimensional stability required for consistent gear engagement under load.
Use this pinion when you require a lightweight, accurately machined 20T / 64 option for motor setups where reduced rotating weight and dependable tooth geometry are essential.
