FANTOM HELIX RS SPEC EDITION Titanium-shaft Rotor Yokomo FA-18613ST  [FA-18613ST]

FANTOM HELIX RS titanium rotor details

The Yokomo FA-18613ST is the titanium-shaft rotor option developed for the FANTOM HELIX RS SPEC EDITION motor series and referenced with JMRCA certification in the original material. It is offered as a direct replacement rotor assembly for competitive 1/10 on-road use under regulated limits.

Titanium provides enhanced surface hardness and corrosion resistance compared with standard steel shafts, which helps preserve concentricity and decrease mechanical wear during sustained race use. This component targets mechanical reliability and consistent timing rather than electrical modification.

Fitment reminders: confirm correct bearing fit and rotor endplay during assembly, maintain the original rotor orientation for the HELIX RS SPEC EDITION motor, and re-verify pinion mesh with the spur gear after reassembly. Use correct tools and avoid forcing components to protect the motor internals.

Race preparation tips: because the rotor is intended to preserve the factory timing profile, direct tuning efforts to drivetrain alignment, gear selection, and ESC configuration. Inspect the shaft frequently and replace it if you notice any scoring or deformation.

For racers and teams using the FANTOM HELIX RS SPEC EDITION motor, the Yokomo FA-18613ST titanium rotor is a dependable replacement focused on sustaining mechanical integrity; always confirm fit and clearances during servicing.
