High-Performance 17.5T: Yokomo FA-19017S FANTOM HELIX RS SPEC

The Yokomo FA-19017S FANTOM HELIX RS SPEC 17.5T motor focuses on efficient speed and thermal stability for race day consistency. It adheres to ROAR rules and is undergoing JMRCA clearance, so it fits the needs of club and regional stock racers.

Key Engineering and Setup Notes

Built around a dual balance rotor, this motor improves torque delivery and smoothness under load. The stator uses a carefully selected metal alloy and the collector ring design has been refined for better conductivity, while the silver-plated solder tabs help preserve solid connections under vibration. Choose between RSR 24mm, RS 25mm (Standard), and RST 26mm rotor lengths to match throttle response to track conditions.

Specifications

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

The Yokomo FA-19017S FANTOM HELIX RS SPEC is a reliable 17.5T choice for racers prioritising consistency and tunability across a variety of stock formats.
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.

Is this motor a good match for club-level stock racing?

Yes. Its ROAR compliance and balanced performance make the FA-19017S a solid pick for club and regional stock categories where consistent lap times are important.

How do rotor lengths affect handling?

Shorter rotors bias the motor toward quicker acceleration, while longer rotors tend to smooth power delivery and raise top speed. Try different lengths to match your track and driving style.

Any recommended setup tips for cooling?

Ensure adequate airflow around the motor, check case clearance, and monitor temperatures in practice runs. Proper cooling helps maintain consistent power and extends component life.
