I want the plane to do and what motors/batteries/esc/props I have. Then find a combo that meets those goals? ''I want my jet to go about 100kmh with a 2S/3S/4S battery and a 30-40A ESC with about 80% drive eff'', if I had this as a goal to strive for would that work?
That's pretty much how I do it, then apply it to what beau0090_99 posted above.
I find it better than starting with a prop, as in cases such as your working from a prop size is either difficult or impossible.
BTW: don't start out by limiting the ESC size you will use, let the numbers determine that.

First question:
How much does your plane weight, and what type of plane is it?
