I got the sc10 4x4 to be different. The belt diddent scare be that was just.one less thing to have to oil and rebuild. Simple and sweet. It is a sight on the track.as well. If I was a better driver I.would place much better. Last race I.took 2nd place aganst 2 losi's and a prolite. Only reason the losi got be was we got in a side by side scuffle and he got me sideways with the extra weight. So I bought the exotek chassis installed now, he's got another thing coming next time
