There have been many discussions over the last two years about this fan. There are at least 3 commercial models that use 2 of these. The consensus is 7 cells wired in series. Maybe 8 if you use nimh. They Draw about 12 amps, and produce ~2-3 oz static thrust per motor. Any more voltage on the standard motors will fry them. You can get upgraded motors that will take more volts, but don't produce a whole lot more thrust, maybe up to 5 oz total with a brushless system ($$$).
The 3 models are 2 different A-10 models and a S-3 Viking. Several members of this group have built similar size models. I'm currently working on a b1-b and an a-10. Stay around 12-17 oz all-up weight and you should be fine.
You can find more info on the fan by searching for kp44 or ejf200 on this forum or on these web sites.

thanks for the help i didn't know that the kp fan was also known by other names
I was thinking of doing an Northrop a-9, a gloster meteor or even a su-25 frogfoot (to go up against all the a-10's and me262's out there)

It's more commonly known as the KP44, since it has a 44mm diameter. Whatever you build needs to be extremely light, due to the low thrust output. It's also relatively slow. I haven't been able to scratch build anything yet that's airworthy for more than a minute, but I'm getting some crazy idea of putting a pair on a mini-IFO, just to be the first one to use EDF indoor over here.
