R/C Trucks

I see quite a few of you have R/C Nitro cars. Maybe someone can help me make a choice? (The R/C bulletin boards that I've found are crappy and wouldn't be of much help.) I'm thinking of buying one of these Nitro 4x4 trucks. I hve my choices narrowed down to the Traxxas T-Maxx or the HPI Nitro RS4 MT Racer. Reasons I like each one:

HPI:
1) Comes unassembled - gives me something to do for the next while (This is supposed to be a hobby)
2) Lower chassis - more stability
3) I could race this (competitively) if I wanted to
4) Dosen't come with Radio or Motor - I can customize right away
5) Less bulky than the T-Maxx - Less prone to breakage

Traxxas
1) Can go more places than the HPI RS4
2) Comes RTR - I can use it the same day I buy it
3) Less expensive

Any opnions on which would be better based on the above points?

Any replies are appreciated..
:) :confused: :)

I agree, I want to know how it works and how to assemble/disassemble then I can upgrade and fix things more easily. I think I'm going to order an MT Racer today! Thanks for the reply atc3434`!:) :) :)

The racing aspect is why I went with an HPI Nitro Mt Racer. It dosen't come with a motor so I can get a high end motor to start. Plus some upgrades are already done on this model (bearings instead of shims etc.) I also like the extra stability of the MT Racer as compared to the Traxxas, this would be necessary for racing.

I also figured if I don't like this so much or don't enjoy racing and want to off-road more I can sell it quite easily and get a T-Maxx.
