Competition-grade rotor for the HELIX RS lineup

The FA-18613ST from Yokomo is the titanium-shaft rotor variant made for the FANTOM HELIX RS SPEC EDITION motors, and the original product notes JMRCA certification. It is supplied as a direct substitute rotor for that motor series, intended for regulated 1/10 on-road competition.

In practice the titanium shaft increases resistance to wear and corrosion versus conventional steel, which helps sustain true running and reduces mechanical drift under frequent race cycles. The unit is intended to enhance mechanical reliability without impacting the motor's electrical characteristics.

Fitment advice: check bearing seating and rotor axial clearance during installation, ensure the rotor is oriented as specified for the HELIX RS SPEC EDITION motor, and verify pinion mesh with the spur after reassembly. Avoid using excessive force when seating the shaft to protect the motor internals.

Tuning notes: because this rotor maintains factory timing, focus tuning efforts on drivetrain setup, gear ratios, and ESC configuration. Schedule routine inspections for shaft wear and replace the rotor if any irregularities are observed.

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.

Does swapping to this rotor alter motor timing or speed?

No. This rotor keeps the factory mechanical timing intact; it is a structural/durability upgrade and not intended to change motor speed or electrical timing.

What should I recheck after installation?

After fitting, recheck rotor endplay, bearing seating, and pinion-to-spur mesh to ensure no binding or excessive play has been introduced.

Can this rotor affect ESC or gearing choices?

Because electrical output remains unchanged, your ESC and gearing strategy can remain the same; use the upgrade to focus on drivetrain reliability rather than altering gearing for performance gains.

How often should I inspect the titanium shaft?

Inspect the shaft before each event for scoring or deformation; replace the rotor if you find any wear that compromises bearing fit or concentric running.
