I recently purchased a Gens Ace 60-120C 3S at 5000 Mah 12 min flight time. Compared to the 5800 Mah Turningy's 40 C that flew for 9 Min on a Quad and Ballooned after a few flights. I would suggest a higher C Rating. It might cost you double but is worth 5 times the flights with the same battery. http://www.youtube.com/watch?v=V_2VNe5I9Sw
Nice video, this will help a lot of people understand about C ratings, amperage and watts.
