This is the Scorpion HK-5025-440 Brushless Motor with 6mm Shaft. Developed for the Logo 600 SE and for those that want to convert their .90 size nitro helicopter to electric power, the 5025-440 features a larger diameter 50mm stator to produce insane amounts of torque with a maximum continuous power rating of 4200 watts at 95 amps, and a peak power rating of 5700 watts at 130 amps!
Scorpion HK Series Brushless Motors are built from the highest quality materials, and deliver quality and performance at an affordable price. The parts are machined on the latest CNC milling machines and gold anodized to provide a beautiful, long-lasting finish. The stators are made with 0.2mm laminations for 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), producing a motor that is virtually impossible to burn up in normal use.
Scorpion Motors are built to last, and are backed with a 2-Year manufacturers 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!
