Introducing the Scorpion HK5-4026-1115KV — part of the fifth-generation HK5 Series, built on Scorpion’s award-winning HK motor platform and tuned for high power, high efficiency helicopter performance.
The HK5 Series is engineered to deliver exceptional torque-per-amp performance while maintaining cooler operating temperatures under heavy load. A redesigned internal fan working with Scorpion’s proven external centrifugal fan dramatically increases airflow through the motor, helping improve cooling and temperature stability during aggressive flying.
The HK5-4026-1115KV 6×32mm shaft version is designed for 550–580 class helicopters on 6S LiPo setups and other high-demand electric applications, delivering up to 4050W peak power.
