ofna stands for "oh f***, not again!"
anyway, id go fot the xtm rather than the tmaxx.i have a friend that has a rusty and his receiver and batteries are TAPED to the chassis until the stuff to fix it comes in. the engine in the maxx, once you get it tuned right, will scream, but thats only if you get it tuned good. over here, it doesnt hold a tune worth crap, but the air pressure etc changes quite a bit and often too. go for the xtm
