 This is the Scorpion HK-3226-1600, 1600kV Brushless Motor. Scorpion HK-3226 motors have been developed specifically for 500 class electric helicopters with 425-450mm blades. These motors are designed to provide all the power that you can use, while still maintaining excellent efficiency and cool running characteristics.
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. 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.
All Scorpion HK-3226 series motors come with 4mm male Bullet style connectors already attached, and include a hardware package that contains 3 matching female Bullet connectors for your speed controller with matching heat shrink tubing. 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 5mm shaft.
Scorpion Motors are built to last, and are backed with a 2-Year warranty against defects in materials or workmanship. However, due to the high RPM of these motors, and the fact that we cannot control the installation and setup, the bearings are not covered by the 2-Year warranty, nor is any subsequent damage caused to the motor by a bearing failure. Bearings are a normal wear item, and as such, need to be maintained and changed periodically. For maximum life, make sure that a sufficient gap is left between the pinion and main gear during motor installation to avoid binding, and put a small drop of oil on each bearing every 5-6 flights. It is the responsibility of the pilot to ensure that the bearings are maintained properly.
