There is about the same (50/50) good and bad said about it! As far as the conversion kit goes XTM makes IMO the most complete kit out there! It comes with steel CVD's and drive shafts so there is no need to buy those. I would get a steel spur gear and a MG high tourq steering servo! I have 2 XTM conveted Maxx's one with a Torq .21 and the other with a Force .25 and both rock!
