So I am looking at the Rally Fiesta, it looks like it could be ok with jumps and not road tracks (Thinking of a track made of clay)

And I was wondering if any one had made it more basher like? I want to get it to race against buggies on a clay raceway that has jumps and turns. One of the guys at the raceway says Slashes and buggies are what they suggest for their track.

I am a bit new to the hobby over all, only bought ready to run cars like the Maxx and Rustler 4X4 VXL.
