I've decided to start this post. I just got back into RC after a 7 year break. I got an xxx-4 and a xx-4. I don't race yet, as I'm still honing my tech skills and driving skills. Hopefully I will get to the track (indoor - dirt) and do some practice.

Like someone mentioned in another post, I don't think the xx-4 is all that bad to work on. I've had the whole thing apart in no time. It's just screws men. Grab the driver and twist

I'd like people to perhaps put up what mods they've done to their vehicle if any and any other pertainent info on this car. Hop ups, spares suggestions.

As I said, I'm no racer, but I've got both cars and I can say this, the xx-4 is much more stable. I can't flip the thing. All the xxx-4 does is flip over. I'm not sure, but I think the xx-4 has a longer wheelbase if I'm not mistaken. I've got a GTB 5.5 in the XX-4 right now and the thing is just scary fast. I'm in the process of building another xx-4 from kit, just so I have a spare.
