Scorpion HK5-4020-850kv
We introduce the fifth generation of Scorpion's renowned and award winning "HK - Series" motors. The Scorpion "HK5 - Series"
The HK5 Series lives up to and exceeds our standards of the most Powerful and Efficient motors with market leading Torque per Amp capabilities. In addition on the HK5 series we focused specifically on motor cooling and motor temperature. With an all new Internal Fan design combined with our proven external centrifugal fan we have nearly doubled the amount of airflow passing through the motor. The result is much improved cooling and cooler operating temperatures.
The HK5-4020-850kv is designed primarily for the SAB RAW 500 helicopter based on the guidelines set forth by SAB Factory directly.
