SkyRC Ares PRO 4 540 Modified 4.5T Sensored Brushless Motor

The SkyRC ARES PRO 4 is a sensored 4.5T modified brushless competition motor designed for 1/10 scale on-road and off-road applications. Featuring dual sensor ports and adjustable timing, the ROAR-approved motor combines advanced sensor technology for linear, cog-free power delivery with a CNC-machined aluminum heatsink can. It is constructed with high-purity copper windings rated up to 220 °C, heat-resistant neodymium magnets up to 150 °C, a precision rotor, and premium ball bearings. For convenient maintenance and fine-tuning, the entire housing is fully disassemblable. Weighing approximately 148 g, the motor has a can diameter of 35.8 mm, a length of 52 mm, and a 3.175 mm shaft.
