Large scale set up


Need some help determining a good powerset up. I have run the stats through moto calc a dozen times and would like another opinion. Here are the specs:
Twin engine set up
Can not have a prop larger than 10" dia
Direct drive or geared is fine
Weight without power system appx 9lbs
950 squares on a semi sym airfoil
looking for 6 min flight times
Ability to take off from grass and resonable airobatics.
Will most likely be a pusher set up. Thanks in advance.

Umm. I did some boring calcs and came up with something like 24-28 cells ( two 12-14 cell packs, one for each motor), and a pair of AXI 2820/12 on 10x7 props.

AUW in the 13lb -14lb region, RC3000 used for decent duration.
