I'm getting conflicted answers on the below setup, and was wondering if someone could help me once and for all. My setup goes like this: SK450 frame, NTM 2826 1000kv motors (9x4.7 props amp draw of around 12A), naza m V2 w/gps, 9x4.7 or 8045 props, Frsky 2.4ghz Rx and a 2200 3S 25C nano tech battery. From what i see online, people are telling me the following is the way to calculate flight time: 2.2 / (total amp draw of motors 48) * 60 = how long in minutes, although that comes out to like minutes. I see people with this exact setup and exact battery with a heavier metal frame saying they get 7-8 minutes. Can someone please help with the amount of time I think i would get? i dont have the quad built yet, but am looking to leverage all the 2200mAh lipos i have, rather than having to buy new ones :( I'm good with 7-8 min flight times, but 2 min would be ridiculous :) Any help someone can give would be totally awesome!!! Just looking for some logic and estimates of what i can "really" expect. Thanks guys!!!!

So I went conservative and rounded up to 12A considering I am using a 3S battery and very similar sized props. So that should generate around 12A I would imagine. Unless of course those numbers seem way off to people who have actually done those calculations. People recently have told me to expect around 8 minutes with this setup. So I'm thinking I am fine, but any feedback you have on my setup or if you disagree with those times, please let me know, thanks!
How much will your quad weigh when it's complete, and where did you come up with 12A per motor?
