Little bit of work to put together.. I had a drill through so it made the work go by much quicker. DO NOT OVERTIGHTEN SCREWS. You're just sinking them into plastic so when its righty tighty until its righty loosey and you've gone too far. I set my drill on a low setting and eased them in and didn't have any trouble though. The car is a pretty darn good size, I'm pretty pleased with it. I plan on getting some white bike tires to slip over the plastic tires and give it some traction, this thing will be a rock crawler in no time.
