Or, get Motocalc.

In most cases, with an electric, more cells, a larger prop, or lower gearing will get you more thrust. Of course, with that increased thrust, you'll use more power, produce more heat and perhaps add more weight.
Motocalc will give you an estimate of how your plane will perform. Don't like it? Change something, check again.
Going from 1 to 2 LiPoly cells will make a *huge* difference in the power you've got. You must have special radio gear if it works at 1 cell Lipoly voltages. Be careful that two cells won't fry something!
