Scorpion HK-4025-550KV (6mm Shaft)

The Scorpion HK-4025 motors have been developed for the 550 to 600 class electric helicopters and the HK-4025-550KV motor is suitable for

the glow to electric conversation of 50 size helicopter. 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.

This Scorpion HK-4025-550KV 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. For maximum strength, this

Scorpion HK-4025-550KV motors feature an 8mm motor shaft that is ground down to a 6mm diameter at the output end to fit standard size

pinion gears. 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 5mm 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!
