I have a T-maxx, one of the old originals with the trx.15 engine. Its been resleeved a few times, but still has the original engine in it. Other than that and the belly pan, not much else is stock. I used to race it at a local track weekly back in the late 90's and as the stock parts broke, I replaced them with RPM heavy duty parts. For a monster truck it is set up fast and low since the track had a lot of tight turns and was mostly loose dirt with a few tacky clay areas.
Here is a pic of it with my Bro's Duratrax MAX-ST
