This product was added to our catalog on February 11, 2013.This is the Scorpion HK-2206-3900 Brushless Motor. The HK2206-3900KV motor was designed specifically for 250 class helicopters, such as the T250 and GAUI-EP255*, as well as ducted fan applications. Since the HK series motors are primarily designed for Helicopter and Ducted Fan use, a prop adapter is not included. Scorpion HK Series 22mm motors come with 3.5mm male Bullet style connectors factory installed, 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.
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 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 custom manufactured to be able to withstand temperatures of up to 200°C (392°F).
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 Scorpion 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.
*NOTE: For GAUI EP-255, customers are required to use a 2.5mm Pinion Gear with this motor.
