Introducing the fifth generation of Scorpion’s renowned and award-winning HK-Series motors: the Scorpion HK5 Series.
The HK5 Series builds on Scorpion’s reputation for powerful, efficient, and high-torque helicopter motors. Designed to deliver excellent torque-per-amp performance, the HK5 platform also introduces major improvements in motor cooling and temperature management.
An all-new internal fan design works together with Scorpion’s proven external centrifugal cooling fan to significantly increase airflow through the motor. This improved cooling system helps reduce operating temperatures and maintain consistent performance during demanding flights.
The Scorpion HK5-4525-535KV is designed for high-performance 700-size RC helicopters running on 12S LiPo power systems. It is an excellent motor option for machines such as:
- SAB Goblin RAW 700 and iLGoblin 700 Raw/Pro/Competizione
- OMPHobby M7 and M7R
- Goosky RS7 and RS7 Ultra
- Other compatible 700-size electric helicopters
With a peak output of up to 10,200 watts, this motor is suitable for pilots looking for strong power, high torque, and reliable performance in demanding sport and 3D flying applications. It may also be used in compatible UAV applications requiring similar power and motor specifications.
Please verify motor dimensions, shaft length, mounting pattern, gearing, ESC requirements, and airframe compatibility before installation.
