Designed for Tight-Corner Touring Circuits

The Yokomo FA-19221S is a 21.5T stock motor aimed at 1/10 scale touring competition under R.O.A.R. stock motor rules. It employs Yokomo’s FANTOM stator, an American-patented design, and is mentioned in recent Japanese touring car rule changes that reference this stock category.

Driver feedback highlights the FANTOM stator's contribution to stronger low-speed torque while staying within the 21.5T stock specification, which can improve corner exit acceleration on technical tracks.

Installation is conventional for brushless 1/10 touring motors and fits common motor mounts and pinion/spur configurations on current touring chassis. Ensure correct clearances and maintain cooling airflow to avoid thermal roll-off during competition.

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

Positioned as a competition-focused 21.5T choice, the FA-19221S offers a torque-oriented character for drivers running R.O.A.R. and recent Japanese touring regulations, and it fits into standard 1/10 touring drivetrains with normal installation and cooling precautions.
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.

How will the FA-19221S change on-track handling?

Expect a bias toward improved low-end torque inside the 21.5T envelope, which can make corner exits punchier and affect traction balance; tune suspension and throttle control accordingly.

Does the FANTOM stator have a patent?

Yes. The FANTOM stator is a Yokomo design that carries an American patent and is intended to influence torque characteristics within the 21.5T stock rules.

What gearing or pinion advice applies?

Gearing choices should be made to suit track layout and the FA-19221S's torque profile; small adjustments to pinion size can help tailor acceleration without breaching stock motor limits.

Any special fitment considerations?

Mount the motor using standard 1/10 touring practices, confirm correct pinion mesh, and keep clearances and cooling pathways unobstructed to ensure stable output during races.
