My nephew got one of these, doesn't look like the toughest build on the front suspension but the car is surprisingly fast and torque for climbing is good. The battery is 5 AA cells together in a pack, and only 800mah. One could easily make up a new pack with nimh AAs for 2.5X run time. Balance leads would be nice as well if you're using decent rechargeables. The USB charger is a bit slow but does the trick.
