Oh, you're welcome.
We talked about this a couple times here. If you use the motor as a brace, the motor screws (and motor itself) take a hard beating.
Mike himself made a post about this, and why he designed his mounts like the way they are. Let me see if I can find it.
edit: found it, read mikes post in that thread. Good point
