Truck came ready to go out of the box. Just charge batterys about an hour. Pair the remote with the car. Very simple. Ready set Go. The thing just flies I started out in the slower mode but soon went to high speed. Battery鈥檚 last about 25 min each with easy change out ..Very powerful and durable smash it up a few times and came out unhurt. Turning is an ease or put it in circle mode. Fast shipping, instructions are easy to understand鈥. One downfall I wish it had a low battery indicator some where. This is what I bought and I am very happy so far with it鈥.
