I bought this intending to drive it around the office and on the roof of our building, just for some fun when work slows down.  It does that just fine.  It's small, light, turns quickly, but it's not as fast as I initially assumed.  I upgraded the electronics to use a 7-cell pack, which unfortunately requires replacing the ESC, receiver and steering servo, as they're all combined into a horrendous plastic maelstrom.  The speed picked up noticeably.
