Seconded on that point. Also, I've found that the Genius upgraded 350mAh 25C batteries are a bit better than even the 300mAh Turbo Ace batteries WOW pushes. I've noticed very little impact to the Mini's flipping ability forward and backward due to the battery's slightly higher weight and larger size. I was able to flip five minutes with the Genius battery, though I brought her down to be safe between 5:25 and 5:30.
