Chances are, you won't find a motor to run that long on only 12 or 14 cells but a 10XL probably will with some IB4200s and the right gearing. It would be close those.
A LONG time! That's some crazy power you'd have there. My guess is that the runtime should be ~45mins depending on the motor and how you're running the buggy.
SH Z-Car, Custom Crawler, 8s Savage, 12s XTM XLB 1/7 buggy, 4wd 4-link rear/IFS Pro4 truck, Custom Hyper 10 Short Course, Belt-Drive Mammoth ST 1/8 truggy, 4s 17.5 MM Pro HPI Blitz
I think that be the best way to go. It would be real close on nimhs. Not saying you will make it but you would have to run out on the last go of the race or so. That would suck.
Peace!
