Also just noticed you listed a LiFe battery. Need to confirm you mean a LiPo? A LiFe battery is not suitable for a quadcopter.

According to prop test data provided by manufacturer,like for my quadropter
i used 4 x turnigy 2836 1000 kv
they have provided approx 1000 g thrust with some 10x5 prop and 3s lipo

so i have approx 4 kg thrust max according to this i have decided the quadcopter size ,
