Joe as you know i have converted my X2 using the TeknoRC mount but had to brace the centre diff to the rear chassis brace to stop centre chassis flex , since the mount is seperate from the diff .
I aslo have a CR mount coming from Mike to try out as he seemed to think a couple of guys are already using it in the X2 .
I posted a thread on this but they haven't responded yet so will let you know when i get it
