Nothing at all wrong with traxxas, both the 2.5 and 3.3 are good engines, I suggest the revo or tmaxx. However, traxxas isn't the only brand out. Do lots of research, nitro isn't hard, but takes lots of patience. Oh, and buy lots of glow plugs, and if you get something with ez start, I recommend to remove the blue wire and use a good quality stand alone glow plug ignitor.
