Scorpion HK5-5024-535KV Brushless Motor (6mm × 55mm Shaft)

Scorpion HK5-5024-535KV Helicopter Brushless Motor

The Scorpion HK5-5024-535KV represents the fifth generation of Scorpion’s renowned and award-winning HK Series helicopter motors. Developed for demanding high-power applications, the HK5 platform builds on Scorpion’s proven motor technology with improved torque, efficiency, durability, and thermal management.

Designed primarily for high-performance 700-class electric helicopters, the HK5-5024-535KV uses a larger stator diameter to generate impressive torque and power while maintaining a competitive overall weight. Compared with the previous HKII-4530-540KV, the HK5-5024 is engineered to deliver stronger performance and improved power capability for modern high-load helicopter setups.

⚡ High Torque and Efficient Power Delivery

The HK5 Series is designed around Scorpion’s focus on excellent torque-per-amp performance. This allows the motor to deliver strong rotor acceleration, consistent headspeed recovery, and dependable power during aggressive collective inputs and demanding 3D maneuvers.

Its 535KV winding makes it particularly well suited to high-power helicopter configurations where smooth power delivery, strong torque, and efficient operation are essential.

❄️ Advanced Dual-Fan Cooling System

Cooling was a major focus during the development of the HK5 Series. The motor features an all-new internal fan design working together with Scorpion’s proven external centrifugal fan system.

This updated airflow system significantly increases the volume of air moving through the motor, helping reduce operating temperatures during sustained high-power flights. Cooler operation can improve consistency, efficiency, and overall motor reliability, especially in demanding 700-class applications.

🚁 Built for High-Power 700-Class Helicopters

The HK5-5024-535KV is intended for pilots who want serious performance from a modern 700-class helicopter. Its combination of a larger stator, high torque output, improved cooling, and robust construction makes it well suited to aggressive 3D flying, high-headspeed setups, and other demanding power systems.
