Good luck, it's a fun competition (I was with the Iowa State team 2012 and 2013)

SDSM&T, 2012, for me. Try 775-18s for a direct drive via BaneBots gearboxes, maybe--that's what we used that year, 4 of 'em. Just make sure your circuit protection--and speed controllers--can handle the current. I don't think we ever blew a fuse (yep, we used inline fuses) but we also had speed controllers that would shut off under high-current conditions (say, about 3-10 seconds into a run) and not reboot. So we got some without that safety and... well... It worked until we dug ourselves into a small hole and got stuck on our last run. We could smell the smoke when we opened the case.
