All of the Scorpion 40mm motors include a cross style backplate mount, but occasionally, you need a spare or a replacement. The Scorpion 40mm Cross Mount is designed to fit the back of the 40mm Scorpion motors and provide a method on mounting the motor to a model's firewall.
The Scorpion 40mm 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 4mm machine screws to attach it to the back of your motor. The mount weighs 16 grams by itself, and with the 4 screws, it weighs 19.5 grams. The hole spacing on the back of the mount where the motor attaches measures 25mm center to center in both directions. The spacing of the outer holes is a square pattern that measures 41mm side to side and 58mm on the diagonal.
Here is a photo of the mount with all the dimensions listed. The one shown below is the type that ships with the motor. The ones sold as replacement parts are black electrocoated.
