depends on the plane I suppose....and I am not sure the exact ratings of that motor

the 8c might work.... run the numbers through Motocalc or pick up a Whatts up (or similar) I didn't want to either, but I'm glad I did....

I use Thunderpower 1320 3S1P packs with good luck and a polyquest 1500 pack (the polyquest is quite a bit bigger but weighs about the same..)

I use this in 3dfaomy style planes.....
