Overview of the Yokomo FA-19021S FANTOM Motor

The Yokomo FA-19021S FANTOM with the HELIX RS SPEC update focuses on balance and thermal control, delivering a more predictable power band for racers tackling mixed terrain or tight club tracks.

What the Helix RS Brings

Conceived to meet ROAR standards, the HELIX RS SPEC features a dual balance rotor that reduces bogging and improves corner exit stability, making it a solid option for both track sprints and rougher off-road races. JMRCA approval is listed as pending in the specs.

Construction and Rotor Choices

The FA-19021S uses a refined stator architecture to achieve a useful combination of torque and efficiency while using durable stator plates. Racers can pick from RSR 24mm, RS 25mm (Standard), and RST 26mm rotors to tune acceleration and top speed to suit their driving style.

Specifications

  • Compliance: ROAR Standard, JMRCA Approval Pending
  • Rotor Design: Dual Balance
  • Rotor Lengths: RSR 24mm, RS 25mm (Standard), RST 26mm
  • Cooling and Heat Management: Enhanced Can Design
  • Connector: Silver-Plated Solder Tabs

The Yokomo FA-19021S FANTOM motor is a practical 13.5T option for racers who want consistent, tunable performance. Its cooling and rotor options make it adaptable to a wide range of setups.
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.

Can I use this motor for dirt tracks?

Yes, the FA-19021S suits hardpack and looser dirt when paired with the correct rotor and gearing. Its dual balance rotor helps maintain traction and reduce mid-corner stalls.

Does it need special cooling mods?

The enhanced can design improves heat dispersion, so additional mods are generally unnecessary unless you are running extreme sessions; good airflow and sensible gearing are usually enough.

Are the rotor changes straightforward?

Changing rotor length requires careful handling and correct shimming, but it is a standard tuning step to balance spool-up and top speed for different tracks.

What about the solder tabs on the connector?

The motor includes silver-plated solder tabs ready for soldering your preferred leads; ensure secure joints and insulation for reliable operation.
