My son and I tried the stock battery that comes with them on the street car and on the off road cars and we got approximatlly 10 minutes give or take a few minutes off road with the trucks and about 15 minutes or so on road. The street car got about maybe 20 minutes, maybe a little less with the stock battery.

We also ran Racers Edge 3300mah batteries and got about an extra 10 or so minutes, never ran the Redcat 3000mah batteries.

Basicaly with the stock set up it boils down to your typical Electric car, only you can fix these if something breaks. They are an awsome deal for the money though you can't go wrong for $110 to whatever bucks for a hobby grade electric car as a beginner into the R/C Hobby. It's just like the Tornado or any of the Redcat cars for the price you can't go wrong.
