http://www.rcproductdesigns.com/EigthScaleParts.htm will alow you to mount the esc over and behind the center diff and get the esc out of dirt. See
http://www.rcproductdesigns.com/Jammin%20index.htm I like mine. Keeps the esc high and dry. Raises the COG a bit but I like the esc out of the way. It is the plate on top. The motor mount is seperate.
