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).
