SkyRC Ares PRO 4 540 Modified 3.5T Brushless Sensored Motor

The SkyRC ARES PRO 4 is a sensored 3.5T competition brushless motor designed for 1/10 scale stock and modified on-road and off-road racing. It features a CNC-machined aluminum heatsink can, dual sensor ports for neat cable routing, and high-purity copper windings resistant up to 220 °C alongside heat-resistant neodymium magnets up to 150 °C. The fully disassemblable, maintenance-friendly housing allows easy cleaning and part replacement with standard RC tools, while the timing can be finely adjusted directly on the motor for on-track tuning. This lightweight, 148 g motor is equipped with a 3.175 mm shaft, premium ball bearings, and a precision-balanced rotor to ensure linear, cog-free power delivery.
