Vincent,
My guess is that it may be marginal.

Here's why.

I fly a 44oz Nobler with a 12-6 prop (8000 rpm) using a 4s2100mAHr Lipo pack. Typically I use less than 1600mAHr out of the pack. Since my average watts during the flight (320 s) is ~290-300 watts. This means the total energy I use (Volts*amps*time) is 96000 watt-seconds (joules) (or 27watt-hrs).

Your battery has less average voltage (I think) than my lipo which had an average output voltage of 14.4V during the flight. So that means you will be pulling more amps to make the 300 watts (=output volts*amps). So the question is whether your pack has enough capacity to do that. The A123 cell can be drawn down lower than the lipo, so maybe it will work, but it is one of those questions that almost can't be answered until you try.

6 cells is ok for 60-65oz stunter with APCE12x6 and 5 minutes flight time

hey! ... nice table:

1 123 for 10oz
2 123 for 20oz
3 123 for 30oz
4 123 for 40oz
5 123 for 50oz
6 123 for 60oz
7 123 for 70oz

Many thanks Igor and Alan

I will order 5 cell packs and post results later

will take me a few weeks to get these and then

at the mercy of the weather for test flying
