FA-18621ST FANTOM HELIX RS SPEC EDITION by Yokomo 1/10 stock motor  [FA-18621ST]

FANTOM HELIX RS summary for event compliance

The Yokomo FA-18621ST, offered as the FANTOM HELIX RS SPEC EDITION, features a titanium shaft rotor and lists JMRCA official certification, making it suitable where stock-class restrictions apply. The description emphasises the materials and certification to indicate steady output under ROAR-style rules without overstating unregulated capability.

As a 1/10 touring car motor, it is aimed at competitors and mechanics who need conformity with event rules. The titanium shaft rotor is the documented technical attribute and is relevant when assessing shaft rigidity and rotational balance for setups.

Standard installation steps are recommended: check pinion-to-spur alignment, ensure motor mount spacing and cooling clearance match your chassis, and confirm wiring and connector compatibility with your ESC. For tuning in stock classes, select gearing and ESC settings that respect class limits and improve on-track driveability.

The FA-18621ST is presented as a competition-aligned, regulation-compatible motor for 1/10 touring car stock classes, with a titanium shaft rotor and official certification for events that mandate specified motor characteristics.
