The HELIX V2 SPEC EDITION is ideal as a stock racing motor for each category, and for classes that use boost or turbo, we recommend high-speed rotation models such as 24mm magnet length, and for racing in blinky mode where boost is prohibited, we recommend a torqueful 26mm rotor. The spare rotors also have a lineup of 25mm, which shows intermediate characteristics between them, so you can acquire your preferred characteristics according to driving conditions and regulations.
