Josh is right in some aspects. As far as durability, Traxxas vehicles are tough, but on the other hand, their target demographic is more towards younger kids. And on top of that they dominate the market. In my opinion I think the Monster Jam "replicas", if we can truly call them that, are for the lack of a more appropriate word crap. The trucks are 2wd and are independent suspension. Two main things that their real life counterparts are not. This was probably done to keep costs down and make the trucks easier to operate and maintain for their demographic, kids. Don't get me wrong though, as an owner of a Traxxas E-Maxx myself I can say that they are tough vehicles, easy to maintain, and parts for them are readily accessible, but as far as realism and true to scale goes, I would've loved if HPI had gotten the license to do the replicas. My Wheely King is hands down a better looking replica of a real life monster. I know you Clod guys will most likely chime in and say that the King is crap too, but for the price point and the realistic look you can't beat it. I for one love the work I've seen on many Clods, but some of us can't afford to drop that kind of money into a truck. My solution for keeping costs low and still having great realism? Buy a Wheely King and put a Traxxas replica body on it. So with all that said, yes I think the Traxxas replicas are crap realistic wise, but you have to appreciate the fact that someone is finally making the trucks that we enjoy and have wanted to see in a "store bought" version for a long time.
