Thanks fot the quick reply. I now realize that I should have went with the Mamba in the first place. As far as the power being to much to control I am hoping to be able to play with the ESC settings with my computer and the EPA on my Specktrum DX3.0 to keep things under control unless I want to let it all hang out. I know the drivetrain will take a beating but all of the parts are pretty inexpensive and easy to fix in a 2wd. That is why I am doing this to my XXX-T and not my E-Maxx.
