Race-proven performance tuned for 1/10 - 1/12 STOCK class dominance.
Stay legal at ROAR-sanctioned events and tracks enforcing "ROAR Approved Motors" while enjoying enhanced cooling and performance from the open, non-epoxy design.
Fully compliant and future-proof under current ROAR rules. This non-epoxy G4R version meets the updated ROAR spec motor requirements (no epoxy windings allowed starting September 1, 2025
Built to the team's exact specifications with the pre-installed High Torque Tuning Rotor (the setup our race team and top event competitors use 99.9% of the time for superior punch, torque delivery, and consistency), delivering the edge you've seen on podiums without individual hand-tuning.
Elite heat management for sustained power under pressure. Innovative fully exposed stator core maximizes heat dissipation surface area, combined with a large rear-end opening structure, ensuring cooler, more consistent runs during long mains and qualifying heats, with improved airflow thanks to the non-epoxy construction.
Dual sensor port versatility for flexible wiring and layout options, accommodating any chassis or installation preference without compromise.
User-friendly high-current solder tabs. Custom widened copper bar spacing makes soldering wires faster, cleaner, and more reliable—perfect for quick pit changes or precise builds.
Precision linearity and smoothness. High-precision Hall sensors paired with a meticulously balanced, high-torque rotor deliver exceptional throttle feel, predictable power delivery, and zero cogging for total driver confidence and control.
Built to dominate with premium components. High-performance stator core, 220°C high-temperature-resistant enameled wire, ultra-precise high-strength bearings, and heavy-duty copper solder tabs engineered for extreme current endurance, ensuring reliability and longevity in the toughest spec racing environments.
Specification:
Notes: The KV value is determined with no load on the motor, with the motor's timing set to default and the ESC timing set to Zero. To ensure optimal performance, it is important to prevent the motor from overheating. If the motor does become too hot, allow it to cool down before using it again.
Recommended FDR (Final Drive Ratio)
The FDR (Final Drive Ratio) is the ratio between the angular velocities of the pinion gear and the tyres. In simple terms, the number of laps the motor will rotate when the tyres spin one lap. Different conditions like track type, grip, tyres, temperature, vehicle weight, gearing mode, driving mode influence the performance of your vehicle and have different requirements on the power system, therefore one FDR can not be applicable for all conditions. All the values in the table are initial FDRs recommended for the motors in Blinky mode. Please starts testing with the recommended values, and determine the final value as per the test results. If no recommended FDR is applicable to your vehicle, please start with a big FDR and then adjust gradually as per the demand.
