what kind of surface conditions do you see on the track?

I am running carpet over jumps right now, so it probably going to be a bit different than what you may need. track size for me is about 50 x 50.

I basically use the Spektrum race setup as a starting point. track small enough that I dropped down to an 11 tooth pinion with the 5.5 550 Tekin motor I am running and that really made a difference in temps. Felt like the sweet spot for the truck.

There was another SC104x4 there too, another driver had the RTR version. Definitely doesn't have the punch like mine does. his stock setup didn't feel too bad though, but does have A LOT of roll in the turns with some traction rolling issues. Could push my setup much harder like the losi drivers could.
