Picked up a Stampede 4x4!!

It's my understanding that the sway bars will work. Any idea what kind of speed you were seeing?

In your opinion, what would be the ideal motor setup for this? Do you really think it needs a 4s setup, to be efficient? I have a couple different routes for power that I'm thinking of, and it's always better to pick a brain such as your's, then pick a nose such as mine.
