I own three nitros currently a 1/10 ST, 1/8 MT and the X-Terminator. She can handle the same jumps I put my savage through, as far as clearance its not right infront of me to give you a precise measurement. I havent broken a thing on it and Ive owed it since early May, the engine even as stock is pretty dependable compared to some others I had to fight with. 1 or 2 pulls and shes roaring, I was going to go with the ofna buggies at first and then I said let me try my chances with this company and Im pleased and I got her for a great price and there are plenty of hop ups. As far as a Tmaxx? I havent seen one on the road just mainly the talk I see in the forums about it, Im thinking about getting one myself to add to the family. So Im not bias to what manufacturers I purchase from, I look at what the product can offer me and how much its going to cost for me to get it in my hands. Sometimes your going to have to sacrifice your happiness for some outdoors fun! Most will tell you to get a MT if you want to bash because the are bulit alittle tougher, I brought my buggie because sometimes you cant run on the streets yet I like speed and the look people get when they see rocks roostertailing towards them[>:] back to my point if you dont know which one.. GET BOTH! good luck
