How many AAs would it take to power one of them bad boys? They're daylight visible and they don't look very big from the ground.

I think you're better off with li-po or li-ion batteries if you're going to power that bad boy. Who knows how many AA's you'll have to hump to get some decent powering off that. Decent to me is 1+ hours.
