Yokomo FANTOM FA-19021S Performance Overview

The Yokomo FA-19021S FANTOM motor series brings the HELIX RS SPEC upgrade to club and circuit racers, focusing on improved rotor balance, a revised can profile, and precision build quality for consistent lap-to-lap performance.

Helix RS Improvements

Made to meet ROAR standards, the HELIX RS SPEC uses a dual balance rotor to cut stalling in tight corners and to boost throttle response across both asphalt and loose surfaces. The unit remains JMRCA approval pending and is tuned for predictable, controllable speed rather than unpredictable spikes.

Design and Stator Details

The FA-19021S stands out with a refined stator layout that balances torque, efficiency, and durability. Improved stator plates increase longevity, and the three rotor length options RSR 24mm, RS 25mm (Standard), and RST 26mm let drivers tailor acceleration and top speed to their track setup.

Specifications

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 tracks suit the FA-19021S best?

This motor is versatile for tarmac club tracks and mixed-surface layouts. Choose shorter rotors for snappier response or the longer RST 26mm for higher top speed where straights dominate.

How should I pick a rotor length?

Select rotor length based on track demands: RSR 24mm for quicker spool, RS 25mm as a balanced option, and RST 26mm when you need extra top-end. Match rotor choice with gearing and battery setup.

What cooling upgrades are included?

The FA-19021S uses an enhanced can and end plate design to improve airflow around the windings, helping the motor run cooler under sustained load.

Is this motor competition legal?

The motor meets ROAR standards and shows JMRCA approval pending in the specifications, so it is intended for sanctioned events where those rules apply.
