Once you have a rough estimate of the watts the motor will put out, you can use that chart I posted in the other thread to figure what size plane it'll work in.

For that plane, if you're looking for 3D performance, you're looking for about 150-200 watts/lb. So at 4lb, you'd want at least 600W.

So is it too big? No.

To crank that juice out of it, you're going to need either 1 4s lipo, or 2 2s lipos wired in parallel.
I second that, but I think Squidbait meant to say that you would need 2 2s Li-po wired in series.

D'oh! That's the second time I've done that. I must have battery dyslexia.... saying "series" when I mean "Parallel"!
