HKIII 4025-730kV Brushless Motor from Scorpion - SCO-333

The Scorpion HKIII-4025 Series Motor is designed for use on 600 class helicopters running on 6-10 cell Li-Po power.  This motor qualifies as an excellent upgrade motor for the Roban 600 class scale helicopters.  Representing the most technologically advanced power source ever offered for a 600 class electric helicopter.

Scorpion Competition 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 Electro-Coated to provide a beautiful, long-lasting finish.  The stators are made with 0.2mm laminations to give maximum efficiency, and minimum Eddy current losses. he 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 high temperatures, making a motor that is virtually impossible to burn up in normal use.

For the best overall combination of quality, performance, and value, we highly suggest using Scorpion Motors in your Roban helicopter!

Brushless Motor Measurement Key

Tech Note:  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.
