Product Details
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 N-50EH style, which are rated
for operation at 200 degrees C (392 F), making a motor that is
virtually impossible to burn up in normal use.
This particular motor is specifically designed for the new smaller
electric helicopters such as the T-Rex 250, and features a 2.5mm output
shaft that fits the stock Trex 250 pinion gears.
All Scorpion HK Series 22mm motors come with the new 2.5mm male
Scorpion 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 use, they do not include a prop adapter.
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.
The Scorpion Motor Bearing Lubrication Kit is now available for
maintaining the bearings in your helicopter motor. To view this
product, please check out the Bearing Lubrication Kit.
If you need mounting screws for this motor, please check out our selection of Motor Mounting Screws.
For the best overall combination of quality, performance, and value, use Scorpion Motors in your helicopter!
