I think you're way over on the weight of this thing. If it's so small that you can only use 7" props, I don't see how you could get over half a kg unless a brick is part of the structure. Assuming you're 750g or less you could easily live with the 3 blade 7x8" props with the 3 cell battery (I'd go larger than the 2200 mAh you said at first if I wanted to fly more than four minutes) I think you have a combination you can live with. Even a 1 kg quad would fly okay with that power system, but I just don't see how you could get to that much weight.
