I ran my jammin for the first time yesterday and it was actually my first time running any 1/8 scale. The car worked pretty awesome, I just have to get used to running 1/8 scale. My setup seemed a little off though, Can someone hook me up with a good setup for a big, bumpy track. The dirt is a mix of hard packed, and loam, but no blue grooving. Traction is good with crimefighters and even the kit tires worked. Any help would be great.
