Features
  • The Scorpion HK-5020-450 motor is designed for 700 class Electric Helicopters, and for people that want to convert their .90 size glow helicopter to electric power. This motor has a maximum continuous power rating of 3770 watts at 85 amps, and a peak power rating of 5320 watts at 120 amps! The larger diameter 50mm stator allows these motors to produce insane amounts of torque. To handle all of this power, the Scorpion HK-5020-450 motor features a massive 10mm main shaft that is precision ground down to 6mm at the pinion end. This allows the use of over-size main bearings, and still be able to fit the stock 700 class pinion gears that have a 6mm bore.
  • 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.
  • 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.
  • The Scorpion Motor Bearing Lubrication Kit is now available for maintaining the bearings in your helicopter motor. To view this product, please check out the Bearing Lubrication Kit.
  • For the best overall combination of quality, performance, and value, use Scorpion Motors in your helicopter!
