Hi I use the Duramax Ice. OMG the 11.1v 1320Mah is the whip. I have Hovered 3 different sessions and have plenty for more about 7 minutes each. When I got home the hobby shop already had charged it up for me.(so I could fly when I got home ) I check it 12.55 flew 7 mins then check the cells 11.50 wow. about 1 hr later showed the wife for about 7 min. more. now its 11.05 that is amazing!

gonna fly again after dinner and then check and charge. going for around 10.6 before charging it with the ice at 1.3 and see what happens

Oh BTW thanks guys higher is much much better not as much ground effects at all.
