If you look in the post above at the times and mah usage I got out of a pack of 5000's, that was with a 2200kv motor. So I think that is the limit on the lowest mah to use. 15 min finals were just about do-able.
Battery wise, I think its pretty much a 'community' thing to go with hardcase LiPo's as nothing is set in stone this year as it is an experimental year so to speak.
