The HUDY 294032 ULTRA-LIGHT aluminium pinion is built for R/C hobby cars where lower rotating mass and tougher tooth surfaces are advantageous. The designation shows a 32T tooth count with the "48" marking included, and the hard coating offers improved wear resistance compared with untreated aluminium.
The pinion is used to adjust drivetrain ratios by varying tooth count, affecting acceleration and top speed. It mounts at the motor/pinion interface and must be aligned with the spur gear to ensure stable mesh; verify the pinion bore and motor shaft dimensions before installation.
Focus on correct backlash and mesh clearance during setup rather than relying solely on the ULTRA-LIGHT label. The reduced mass can influence throttle response, especially in lower-weight vehicle configurations.
Ideal where aluminium lightness and a hardened tooth surface are preferred; always confirm mechanical fit and gear mesh compatibility with your spur gear and motor shaft before competitive use.
