The Scorpion HK-4035 motors have been developed
for the newer 600 and 700 class electric helicopters that are now coming
onto the market. 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.
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 shrink
tubing. This Scorpion HK-4035 motors feature an 8mm motor shaft
diameter. 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.
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.
For the best overall combination of quality, performance, and value, use Scorpion Motors in your helicopter!
