Competition-Optimized Design
Every Detail Tuned to Win. Engineered to Excel.

Low-Resistance Solder Tabs
High-quality tabs minimize power loss, ensuring maximum current flows straight to the rotor.

Stay Cool: CNC Aluminum Heatsink Case with Rear Venting
The precision-machined aluminum case dissipates heat efficiently, while a large rear vent boosts airflow over the Hall sensor for stable, reliable performance.

Global-Grade Bearings & Precision Shaft for Ultra-Smooth Control
Top-tier international brand bearings paired with a high-precision shaft ensure buttery-smooth, accurate operation—race after race.

High-Purity, High-Temp Copper Windings
220°C-rated, high-purity copper windings ensure efficient, low-heat power delivery for stronger punch and higher top speed.

Precision-Balanced, Heat-Resistant Rotor
Meticulously balanced for ultra-smooth rotation and minimal vibration, the rotor is crafted with a 200°C heat-resistant, explosion-proof structure—delivering consistent power, higher RPMs, and lasting durability.

200°C High-Temp Neodymium Magnets
200°C heat-resistant neodymium magnets and a high-efficiency iron core deliver strong torque, stable magnetism, and consistent performance under pressure.

Advanced Sensor
No Hesitation. Just Precision.
ARES PRO 4 features advanced sensor technology for ultra-smooth throttle response and precise low-speed control—crucial for technical tracks and tight corners. By eliminating cogging, or hesitation at low RPMs, it delivers seamless, immediate power exactly when you need it.

Adjustable Timing.
Any Track.
Adjustable timing is the core of brushless precision, enabling power delivery to adapt seamlessly to any track condition.

Low Timing (0-20deg)
Later power delivery creates smooth output, stable torque, and linear starts.
Ideal for precise control through continuous corners, preventing sudden wheel spin.

Mid Timing (20-40deg)
Balances instant punch with smooth sustained acceleration.
Perfect for mixed circuits with straights and curves, such as drift tracks

High Timing (40-60deg)
Earlier power delivery drives rapid RPM climbs and explosive top speed.
Best for flat-out straights, achieving higher RPM under the same voltage.

Redundant Dual Sensor Ports.
Zero Hassle.
Placed in different orientations, the dual sensor ports simplify wiring and offer built-in redundancy. If one fails, the other keeps you running—seamlessly and reliably.
Plug in. Power on. No setup—just pure performance.
*Before use, please confirm your ESC’s continuous/peak current, supported cell count, and sensor port type to ensure compatibility with the motor specifications.

Modular by Design.
Built to Stay New.
ARES PRO 4 features a fully rebuildable, modular design—allowing easy disassembly of the housing, stator, windings, and bearings with standard RC tools.
Clean, service, and swap components to keep performance sharp and consistent, race after race.
Always fresh. Always in control.

Multiple Turn Options.
Ready for Any Track.
Each turn rating gives your car its own distinct character.
Lower turns deliver explosive speed and powerful thrust.Higher turns offer smooth, consistent power for confident control, lap after lap.
