Actually it's probably due more to the fact that that truck is not very well known and to be honest I don't think I've ever even seen a video of one running.
Get us some vids already!
Nobody carries anything Tamiya around here. Wish they did. I like the TNX, it was one of my choices for my first monster. The Savage won out due to parts availabity.
Here is my TNX. It was a Terra Crusher that I converted in to a TNX 5.2 in all but engine. It has an OFNA/PICCO .26 outlaw engine and an OFNA pipe. I used a earlier version of the body because I hate the looks of the 5.2 body. This thing has awesome power. I do hate the fact that Tamiya parts are impossible to find but I think this is a top quality truck.
