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. The new SII series motors are an updated and improved version of the popular 30mm motors that have been so successful. Scorpion starts with high quality aluminum alloy parts that are produced on the latest CNC milling machines. These parts are then gold Electro-Plated 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.

All Scorpion SII-30mm motors come with Scorpion's new 2.5mm male Bullet style connectors already attached, and include a complete hardware package that contains the following: 3 matching female Bullet connectors for your speed controller, a cross style backplate mount with 4 screws, and a threaded shaft prop adapter.

Scorpion Motors are built to last, and are backed with a 2-Year warranty against defects in materials or workmanship. For the best overall combination of quality, performance, and value, give Scorpion Motors a try!
