The Scorpion SII-6530 Aircraft Motors are the second generation of high efficiency electric motors from Scorpion that are widely used to power 50cc to 80cc size aircraft. The re-designed SII-6530 motors are an upgraded version of the earlier S5545 motors that feature a new magnet configuration along with an updated housing design which provides higher efficiency, higher power and less eddy current losses with lower internal resistance than our previous S-55 series.

Scorpion starts with premium materials including 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 by top grade 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 custom manufactured to be able to withstand high temperatures.

Scorpion Motors are built to last, and are backed with a 2-Year warranty against defects in materials or workmanship.
