Scorpion HK-3026 motors have been developed for the newer 500 class electric helicopters (425mm blade) that are becoming so popular. 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, and are wound with wire that is rated at 180 degrees C (356 F). The magnets used in Scorpion Motors are rated for operation at 200 degrees C (392 F), making a motor that is virtually impossible to burn up in normal use.

All Scorpion HK-3026 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.

Got this Motor in a HK500 Heli. It got gigantic Power, I needet to limit Current to 100A,( = 2,5KW !) or it will rip the Main Gear. With normal flying on 6S its barely warm, doing 3D with 3500mAh in 5min. it got about 70Deg. C. outside.
Only Problems I had was the Shaft beeing slightly to small (Diameter) and starting to move inside the Bearings and by that ruin the Bearings.
With a self made precision Cobalt-Steel shaft and SKF Bearings no more problems since a year now. Bearings now fit very strongly on the Shaft, while the original simply fall down on the original shaft. My Motor is a 2009 make, I cant say if there has been any change on the shaft quality.
Probably 250h of runtime until today.
With 15 T Pinion and a 75A CC-Ice its good for max 2350 U/Min Headspeed - For Higher HS you need a bigger Pinion.
