You can install MINI and MICRO servos in thin wings, and REMOVE them with these servo FLAT MOUNTS!

Servo Flat Mounts allow the servo to lie with its side flat against the bottom so the servo installation will take up no more depth than the actual thickness of the servo itself. About 1" long and 1/2" high, 6 screws and plastic washers. In a thin wing the aileron servos need to be mounted like this. Servos can sometimes be mounted by this method inside fins and horizontal stabs. You can shorten the vertical legs to the thickness of your servo. Insert a small screw and washer into the hole in the leg to clamp the servo in place. The screw can also hold the access plate or a fairing in place on top of the servo. Fits all "mini" and "micro" servos.
