Here it is, the new V2 series HK-2221-10 motor. Improvements include
better cooling with the integrated centrifugal blower fan, higher efficiency
with a new stator design and a new threaded-on flux ring for more solid
construction.
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.
All
Scorpion HK Series 22mm motors come with 3.5mm male Bullet style connectors
already attached, and include a hardware package that contains 3 matching female
Bullet connectors for your speed controller and a cross style backplate mount
with 4 screws. 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 3.175mm
shaft (1/8 inch).
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.

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!
