Bruce, I didn't like having the MM on the chassis either. I took some 1/2" aluminum rod and cut them about 1.75" long (or whatever works for you) and then drilled and tapped 5mm holes on one end and 4mm holes on the other. I used the 5mm holes to mount the rods to two of the existing motor mount holes. I then cut a 1/8" thick piece of aluminum plate that would accommodate the MM and punch two holes into it and screwed the plate to the rods and then used some good servo tape to stick the MM to the plate. it all looked like this...
Sorry, but that's the only pic I had of my Turmoil showing the MM mount.
I think that my standoffs were a bit long. You only have to make sure that the plate clears the chassis brace and drive shaft.
