The Yokomo FA-19221S is a 21.5T stock motor designed for RC touring car competition where R.O.A.R. stock motor rules apply. This RC-scale motor uses Yokomo’s FANTOM stator design, which holds an American patent, and is referenced in recent Japanese touring car regulation updates adopting the same stock class.
Performance notes from domestic team drivers who have tested the unit indicate the FANTOM stator emphasizes low-end torque within the 21.5T stock envelope, making it suitable for tight-corner tracks and technical touring layouts. The motor is presented as a regulation-compliant option for club and national RC touring events.
Installation is standard for 1/10 scale touring motors and aligns with typical brushless motor mounts and pinion/spur setups used on modern touring chassis. When fitting, preserve recommended clearances and cooling airflow typical to RC touring configurations to maintain consistent performance under race conditions.
As a regulation-focused 21.5T option, the FA-19221S targets pilots seeking a torque-oriented stock motor that fits R.O.A.R. and recent Japanese touring rule sets, and it integrates into standard 1/10 touring car drivetrains with routine installation and cooling considerations.
