Wow, I bought one a couple days ago and man is it fast!
I took the top off just to see what was in it...too complicated (and expensive) for me to try and mod.
I put it on our kitchen floor and it did doughnuts all over the flace at full speed with the wheels turned, then I put the wheels back straigh and the other way and it kapt circling in the same dirrection. Lots of power in this thing.
Oh yeah, it was mentioned that it has working headlights i think, but also, if you turn on the turn signal, it goes off automatically after you get done turning the front wheels.
I like my new toy.
