BG364711952 It's 4WD, with separate motors for the front and back axles.

BG364711952 Not really - it's pretty much a case of what you see is what you get (it is only a cheap, toy-grade model after all). The battery is a standard 6-cell AA NiCad pack (7.2V), with a SM 2-pin connector, so that's an area where you could upgrade (and probably should, since the included battery provides only a short running time, and takes a long time to charge). The motors are a pair of unbranded "280" size (interchangeable with "370" size), so they could also be upgraded to more powerful versions - though there may be a risk of damage to the electronics if they draw too much current, and the gears and bushes are all just plastic, so they might wear out quickly too. On the plus side, everything is held together by small screws (there's no glue or plastic tabs anywhere), so it's very easy to take apart without breaking anything.

BG364711952 Slow. It's designed for rock-crawling, not racing.
