All of the Scorpion S-30mm motors include a cross style backplate mount, but occasionally, you need a spare or a replacement. The Scorpion 30mm Cross Mount is designed to fit the back of the 30mm Scorpion motors and provide a method on mounting the motor to a model's firewall.
The Scorpion 30mm Cross Mount is made from strong aluminum alloy and finished in a durable and attractive black Electro-Coat finish. The mount comes packaged with four 3mm machine screws to attach it to the back of your motor. The mount weighs only 3.8 grams by itself, and with the 4 screws, it weighs 4.7 grams. The hole spacing on the back of the mount where the motor ataches measures 25mm center to center in both directions.
