Here is what they say in their website
Scorpion Power System is pleased to announce the release of our new series of Brushless Outrunner Motors. These motors raise the bar in both quality and performance, and are establishing themselves as the new Gold Standard for model aircraft power! All of the Scorpion Brushless Motors are manufactured from the finest quality components using state of the art CNC machine tools. Every component of the motors are of the highest quality, from the materials used, to the box they ship in. They are designed to provide reliable power for your model aircraft at affordable prices, offering a total performance solution.
Scorpion Motors are designed from the ground up with the best quality components available to provide an excellent value for you, the R/C modeler. We utilize high quality aluminum alloys that are CNC machined and anodized for a fit and finish that is second to none. Unlike other motor manufactures that use off-the-shelf NdFeB magnets with a maximum Curie temperature of 80 to 100 degrees C, our motor magnets are custom manufactured to be able to withstand high temperatures. The wire we use to wind the stators is rated to 180 degrees C (356 F), so it can take the heat and keep on performing. This all adds up to a motor that can provide you the power you need, without going up in a cloud of smoke if you push it a little too hard. With all these features, you would expect to pay top dollar for a motor of this caliber, but with our efficient manufacturing procedures and streamlined distribution chain, Scorpion motors retail for about 1/2 the price of other "Name Brand" Brushless Motors, making them one of the best overall values on the market today. We are so confident in the quality of our motors that we back them with a 2-Year Warranty against defects in materials and workmanship. You deserve the the best quality motor available at an affordable price, so the next time you need a brushless motor, do yourself a favor and give Scorpion Brushless motors a try, you will be glad you did!
What's included?
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).
About this HKII-2221-2010 motor
For helicopters that are designed to run on a 6-cell pack, like the Outrage G5, the new HK-2221-2010 motor
is the one to use. This motor was designed for 6-cell Li-Po use to take full advantage of the efficiency that is
available from running a higher voltage system in a 450 class helicopter. Many people are converting their
Trex 450 and Thunder Tiger Mini-Titans to 6S power, and this is just the motor for that.
