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.

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.
