Rear ESC mount compatible with YD2-Z, SD1.0, and others.
It is compatible with any YD2 version which has the interchangeable quick-change diff cover. (Older YD2-s and E variants will not work)
The two screws holding the diff cover will be fed through the print before the cover, according to the images.
The mount can also be flipped upside down to provide a higher ESC mounting position.
