30 Minute Main?

[RBMike]

To me, jhautz has a great combo for getting there. We do not run 30 minutes at my local tracks so I have not done it my self but I have some input. My race set-up is an MBX6 with a Neu 1512-3DF, MMM(17.5 cut-off) & 5S 3850mAh (Thunder Power). Geared 17/46 my car will run over 20 min every time on medium & smaller tracks. My motor is always about 130 deg after that time & the fan on my MMM never turns on if the air temp is below 75 deg. On loose tracks my run time does drop a few minutes.
