Scorpion HK Series Brushless Motors are built from the best materials available, and are designed to provide both quality and performance at an affordable price. Scorpion starts with high quality aluminum alloy parts that are produced on the latest CNC milling machines. These parts are then gold anodized to provide a beautiful, long-lasting finish. The stators are made with 0.2mm laminations to give maximum efficiency, and minimum Eddy current losses. The stators are epoxy coated to prevent shorts, and are wound with wire that is rated at 180 degrees C (356 F). The magnets used in Scorpion Motors are custom manufactured to be able to withstand temperatures of up to 200 degrees C (392 F).
All Scorpion HK Series 22mm motors come with 3.5mm male Bullet style connectors already attached, and include a hardware package that contains 3 matching female Bullet connectors for your speed controller, heatshrink to cover the bullet connectors and mounting screws. Since the HK series motors are primarily designed for Helicopter and Ducted Fan use, they do not include a prop adapter. If you intend on running a prop on this motor, you will need to purchase a prop adapter for a 3.17mm shaft (1/8 inch).

Customer ReviewsWrite a review
I have 2 of these in 6s 450s running on a Castle Edge 50 Lite and they are absolutely unboggable. They come down warm but not hot and they're easy on the batteries.
This motor is a perfect, drop in replacement, in the Curtis Youngblood Stingray, if you want to go 6S. The perfect battery size seems to be 6S 2200mAh.
I run these on all my custom stretched 450s now. And there is no going back. I picked up a full 2 to 3 minutes in flight times doing the same routines over any of my 3s setups. Plus, there is mind boggling power right up till the end, no fade, none. My components come down barely warm to the touch. This tells you how efficient the system is running. Unlike running the 3s setup where I could fry eggs on the motor and esc. Pretty much the same results on every forum the world over from guys who have done this. And they all rave after the changeover.
Plus, this system is far far easier on batteries. I have over 250 to 300 flights on some of my 1300ma 6s batts and they still perform well.
I did have to convert my fleet over to microheli delrin gears. On stockers I was blowing through them just doing pitch pumps due to how wobbly and non concentric the stock gear sets were. The incredible performance this motor produces will find and expose every weak link in your system.
Still, I will never fly a 3s or even 4s system after this ever again.
This upgrade made my helis into over driven little power hungry monsters on steroids!
