I didn't use any instructions I was just kinda bored in my room and basically there's a motor at the back mounted on the back axle, with a wheelie bar mounted on the motor but behind it so then. If the car is too powerful or sm it will hit the wheelie bar and go down, uh there's suspension which I didn't intend on adding but that's pretty cool and there's structural support underneath which without it, the car will fold so I added that later on to my build. submitted by ...
