Engineered 21.5T Stock Motor for Technical Courses

The Yokomo FA-19221S is a 21.5T motor intended for RC touring competition where R.O.A.R. stock motor regulations are enforced. It incorporates Yokomo’s FANTOM stator design, which holds an American patent, and the unit is referenced in recent Japanese touring car regulation updates tied to this stock class.

On-track reports from domestic teams suggest the FANTOM stator skews the motor's character toward stronger low-end torque inside the 21.5T rules, making it effective for tracks that demand controlled exits and precise throttle modulation.

Mounting and installation are standard for 1/10 touring motors and match common brushless motor mounts and pinion/spur arrangements used on contemporary touring chassis. Take care to set clearances correctly and preserve cooling paths to keep output consistent during extended runs.

Specifications

  • Item Yokomo FA-19221S motor
  • Material FANTOM stator (patented)
  • Model Number FA-19221S
  • Compatibility Compliant with R.O.A.R. stock motor rules, adopted for Japanese touring car events
  • Motor Type 21.5T stock

Marketed as a rules-compliant 21.5T option, the FA-19221S suits pilots seeking a torque-prioritised stock motor within R.O.A.R. and recent Japanese touring specifications, and it integrates with standard 1/10 touring drivetrains following routine installation guidelines.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What regulations is the FA-19221S made to meet?

The FA-19221S is manufactured as a 21.5T stock motor intended to comply with R.O.A.R. stock motor regulations and is noted in Japanese touring car rule updates referencing that stock class.

How does the FANTOM stator change motor behavior?

The FANTOM stator design concentrates on delivering usable low-end torque while remaining inside 21.5T limits, aiding acceleration control and corner exit traction on twisty circuits.

Which chassis are guaranteed to fit?

The documentation lists the MRTC-BD7RS as a supported platform. For other chassis, verify motor mount spacing and pinion engagement before assuming compatibility.

Any recommended service or care?

Routine checks such as confirming secure mounting, correct mesh, and unobstructed cooling airflow will help the motor maintain peak performance under race conditions.
