Features:
1. ROAR-certified ARES PRO 4 features professional-grade power output. Built with high-temperature copper windings & neodymium magnets, it delivers strong torque, higher top speed and stable performance under heavy load across all race tracks.
2. Race-optimized construction adopts low-resistance solder tabs to minimize power loss and maximize current transmission, bringing outstanding acceleration and consistent racing performance for RC competitions.
3. Precision CNC aluminum heatsink case with rear ventilation optimizes airflow around Hall sensor, accelerating heat dissipation to maintain stable long-time operation during intense races.
4. Premium international bearings paired with precision shaft & dynamically balanced 200°C explosion-proof rotor greatly reduce vibration, enabling ultra-smooth rotation, high RPM and extended service life.
5. Advanced sensor eliminates low-speed cogging & throttle delay for precise corner control; customizable 0°~60° adjustable timing switches power mode for corner/drift/straight-track
racing as needed.
6. Dual-direction redundant sensor ports simplify wiring and keep racing going if one port malfunctions;
7. Seamlessly matched with SkyRC TS50/TS120/TS160 ESCs via proprietary algorithms for sharp throttle response; also tunable with SkyRC Motor Analyzer to unlock the motor’s full racing potential.
Description:
ROAR-approved SKYRC ARES PRO 4 racing motor delivers stable powerful performance with premium heat-resistant components, adjustable timing, dual sensor ports & modular build, perfectly compatible with SkyRC ESCs and tuning analyzer.
