RC Servo Mount, Box & Cover

This is a mounting system that I use for 9 gram sized servos.
For large foam aircraft I glue the box in place then mount the servo mount to it using 4 * 3mm screws, placing a small piece of foam between the servo & the box to secure the servo.
For smaller foamies I use hot glue to glue the servo to the mount plate & then the mount plate to the foam.
For balsa planes I use hot glue to glue the servo to the mount plate then screw the plate to the plane.
The cover can be used in all configurat
