Track-Focused Power: Yokomo FA-19017S FANTOM HELIX RS SPEC 17.5T

The Yokomo FA-19017S FANTOM HELIX RS SPEC 17.5T motor is built for consistent top-end speed and efficient power delivery across a range of surfaces. It meets ROAR standards and is progressing through JMRCA approval, making it a solid option for stock-class competitors in current race rosters.

Design Details and Driver Adjustments

This unit uses a dual balance rotor to boost torque and midrange response. The stator is made from a refined metal composition and the upgraded collector ring improves conduction, while silver-plated solder tabs offer dependable electrical connections. Three rotor lengths are offered: RSR 24mm, RS 25mm (Standard), and RST 26mm, so racers can fine tune acceleration and top speed for different tracks.

Specifications

  • Rotor Lengths: RSR 24mm, RS 25mm (Standard), RST 26mm
  • Compliance: ROAR Standard
  • Design Improvements: Enhanced rotor balance, case design, and wire cooling

For racers chasing a performance edge, the Yokomo FA-19017S FANTOM HELIX RS SPEC delivers strong speed and reliable operation, suitable for both on-road and off-road stock events.
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 run this motor in off-road stock classes?

Yes. The FA-19017S is built with torque and durability in mind, making it a good match for off-road stock racing when paired with appropriate gearing and setup.

Which rotor length suits tight technical tracks?

Shorter rotor lengths like the RSR 24mm generally improve acceleration and responsiveness, which helps on twisty circuits where immediate throttle response matters.

How should I maintain the collector ring and tabs?

Keep the collector ring clean and inspect the silver-plated solder tabs for secure joints. Light contact cleaner and routine visual checks will help maintain consistent performance.
