Here are a couple of pictures of my M24 Mid with a Mini-Z motor mount. I found out the motor mount lines up perfectly using the Mid's suspension plate. The only thing that must be done is add an extra hole -- better yet, make a shorter plate using CF as I think the Mid's plate is too long for this setup. Or make them like o-plates and call them donut plates
Using the Z motor mount is great because I get to use my Mini-Z wheels, diff, and motors while taking advantage of the Mid's superior steering mechanism and ability to use electronics of my choice. The front will accept Mini-Z wheels without modification.
