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.

Used in Sebart Katana 30E with 3s setup - plenty of power!
Bearings quality is very poor. I replace them after one flying session because of significant bearing play.
In general - very good motor, but needs bearing replacement to quality ones.
Bearings size 10x5x4.
