Yokomo FANTOM HELIX RS Spec: Precision Torque and Track Stability

The Yokomo FANTOM HELIX RS Spec Motor appeals to racers who want measured power and engineering that supports tight control. Engineered to ROAR standards, the unit benefits from refined rotor balance, a stable case layout, and a stator configuration designed for efficient torque output. It suits drivers who prioritise consistent lap performance over raw, unpredictable power.

Stable Rotation with Advanced Rotor and Stator

The motor's dual balance rotor minimizes vibration and aids in cleaner power delivery through the powerband. Together with the optimized stator, the design yields reliable torque and RPM while maintaining efficiency. The titanium shaft option, offered in Japan, helps prevent stalls in technical sections.

Flexible Setup for Different Tracks

Choose from RSR 24mm, RS 25mm (standard), or RST 26mm rotor lengths to tailor response versus top end for specific surfaces. The improved collector ring and silver-plated solder tabs are focused on durability under race conditions.

The Yokomo FANTOM HELIX RS Spec Motor provides a tunable and dependable platform for racers who want controllable performance across varied track layouts.
