Default Sig Rascal 110 - AXI 5345 and weight

I am contemplating using a Sig Rascal 110" as a base for an aerial photography and had a question regarding weight. I currently have an AXI 5345-14, A123 Batteries, and a Phoenix 85 that is from another project that I would like to use if I could. From what i've seen from other posts this looks like it would be plenty of power for a Rascal 110. Sig recommends a takeoff weight of 11-13lbs. Each set of A123 batteries weighs 2lbs and puts out 39.5V @ 2300mah. I would like to get the most run time possible by adding more batteries. I do realize that I could get a little more mah from lipo but I already have the A123's.

A couple of questions:
If I were to aim at a weight of 25lbs would I still be able to get off the ground (this puts it @ ~2.5lbs/ft^2)?
Does anyone know how much the Rascal 110 weighs empty?
I saw on another post that ~100 watts/lb is what trainer flyers use. The AXI draws ~85A @ 39.5V = 3357watts / 100 watts/lb = 33.6lbs. Did I do this right?

If anyone has any other suggestions they would be greatly appreciated.
