The X-T has different mounting holes, but if you get an un-reamed body then it should fit. There's a company in the UK that has put 1/8 on road bodies onto the Rex-X (UK equivalent) so almost anything is possible. Links to this site are in my web page.
The X-Term has some weaknesses - the rear diff case has lots of problems if you jump & land on the wing. The case breaks apparently but it's a US$8 part so not too bad, plus it's not hard to make a brace to add support & strength. Many people have done this and not broken the diff case again.
I've hammered mine around an on-road course, but done very little off-road yet. I haven't broken a rear diff case, but have broken 2 front lower suspension arms. These are AU$16 for 2 at my LHS, so should be around US$5 each or better.
The 24.7 has a lot of torque, but supposedly not a great top-end.
They are also sold in Europe and Australia by GV and called a Rex-X. There's a number of Alu and Carbon hop-ups and the buggy is sold in 3 setups - RTR, RTR Deluxe (a few hopups including bigger cooling head) and a PRO which has no engine or electrics.
Personally, they seem to be excellent value for money. Mine cost AU$650 here in Australia, but they're at $495 right now. I think they have "specials" occasionally in the US where the RTR version comes in at US$299.
p.s. have a look at Global Hobby's forums - there's a link on my site at http://rc.dyn.ro
