3300mAh at 18V, I would say definitely. I drove Conker around uni for about 30 mins and only took 2000mAh out of my lipo. So even if I trebled the average drain it would still give me 10 mins drive time in combat!

(Though I would get someone else's thoughts to cos I have 0 experience in combat)

Out of Interest, will it run upside down with the back wheels touching the ground?
