Scorpion Brushless Motors HK 40mm Series

Print version, (22mm Series, HK 22mm Series, 30mm Series, HK 30mm Series, 40mm Series)

The Scorpion HK-4035 motors have been developed for the newer 600 and 700 class electric helicopters that are now coming onto the market. There are 2 models of this motor initially available, a 500Kv model and a 560 Kv model. These motors are designed to run on 10-12 LiPo cells, and can produce up to 4200 watts of power! They also work great in aircraft needing a high Kv motor such as pylon racers and hotliners. These motors are designed to provide all the power that you can use, while still maintaining excellent efficiency and cool running characteristics.

All Scorpion HK-4035 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 shink 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 6mm shaft; 40mm motor mounts are available here. Read more about Scorpion Motors and Scorpion 6S ESC.
