About the HK5-4525 Brushless Motor


Extreme Power and Torque

The Scorpion HK5-4525-535kV brushless motor delivers unmatched torque per amp and up to 10,200W of power, making it ideal for 700-size helicopters and high-demand UAV applications. Its manually wound ultra high-temperature windings rated above 250°C, combined with imported high-quality bearings and a hardened steel shaft, ensure smooth operation, maximum power output, and long-lasting reliability under extreme conditions. Specially designed ARC magnets further enhance efficiency and torque, giving pilots precise control and responsive performance.

Advanced Cooling Design

The HK5-4525-535kV features an innovative dual-fan system with a updated internal fan and a proven external centrifugal fan, nearly doubling airflow through the motor. This extreme cooling reduces operating temperatures by 20%, improves durability, and maintains peak performance during extended flight sessions. Optimized for 12S–16S LiPo batteries with 690–720mm blades, it offers flexibility with blade size selection while minimizing maintenance, making it a top choice for serious RC enthusiasts and UAV operators.
