If you do a search you should find something. I have 2 TMaxx with the 2.5 motors and they run great.
I only run one of the trucks regularly (My Wife's) Most time when I run I use my buggy for bashing. I am thinking of selling my TMaxx. After I broke it in I have not driven mine since.
I figure I could always drive my wife's TMaxx when I want. If I keep mine I need to modify it. I find just stock is to boring and breaks to much. Everytime she takes it out it breaks something. I bash my OFNA buggy much harder and the only thing happens is it gets very dirty.
I would like to get the Sirio .18 for my wife's TMaxx.
