The Tamiya 3515005 17T aluminum motor pinion is designed around a 0.8 module tooth profile to provide clean engagement and steady torque delivery across hobby RC models.
This 17-tooth pinion uses aluminium to lower rotating mass while keeping sufficient strength, making it useful for drivers chasing crisper acceleration on loose or hardpack surfaces.
The Tamiya 3515005 fits into many 0.8 module gear trains with accurate tooth spacing. It is a practical replacement or upgrade for owners needing a 17T aluminium option.
