The HK Series motors are high Kv versions of the popular 22mm Scorpion Outrunner Motors. They are designed for applications requiring a fast motor such as Helicopters, Ducted Fans and Hi-Speed Direct Drive applications such as Mini Hotliners and Zagi type flying wings. They all have 9 pole stators and 6 magnet poles using the same 200°C N50 magnets and 180°C magnet wire as all other Scorpion motors. Suitable pinions for helicopter use can be found here.

All Scorpion HK 22mm motors come with 3.5mm male Bullet style connectors already attached, and include a hardware package that contains the following: 3 matching female Bullet connectors for your speed controller and a cross style backplate mount with 4 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 running a prop on an HK 22mm motor, you will need to purchase a prop adapter for a 3.175mm shaft (1/8 inch). Read more about Scorpion Motors and Scorpion ESC. Spare shafts, and motor mounts are available.

Scorpion have commissioned Louis Fourdan to create a special version of his motor calculator. This is an awesome tool which allows you to play around with various power and prop configurations on different motors to see how they will perform. You may download the latest version from here.
