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. 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 0.20mm 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 40mm motors come with the new 3.5mm Scorpion Bullet connectors already installed, along with a set of matching female connectors for your speed controller, and include a complete hardware package that contains a cross style backplate mount with 4 screws, and threaded shaft prop adapter.

The new Scorpion 4035 series airplane motors are built around an 8mm motor shaft for rock solid stability and larger 16mm x 8mm bearings to be able to handle the higher prop load
