Scorpion HK5-4026-545KV (6x32mm shaft)
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 HK5-4026-545kv is designed for 550 - 580 class of helicopter running on 12s battery, or other UAV application requiring up to 4218w of power!
