All of the Scorpion 55mm motors include a cross style backplate mount, but occasionally, you need a spare or a replacement. The Scorpion 50mm Cross Mount is designed to fit the back of the 55mm Scorpion motors and provide a method on mounting the motor to a model's firewall.
The Scorpion 55mm Cross Mount is made from strong 4mm thick aluminum to support the motor. The mount comes packaged with four 4mm machine screws to attach it to the back of your motor. The mount weighs 35.2 grams by itself, and with the 4 screws, it weighs 38.1 grams. The hole spacing on the back of the mount where the motor attaches measures 32mm center to center across the diagonals. The spacing of the outer holes is a square pattern that measures 63.5mm side to side and 90mm on the diagonal.
