Regarding how to pick the right ESC/motor/prop combo, please read the relevant threads in the "Gems" list (especially the ones with topic names "Understanding electric power systems" and "Amp rating and motor size").

A 45 A ESC for a 30 A motor sounds fine! Which motor did you finally make up your mind for?  Smiley

Lets get down to understanding what goes into selection of the ESC .
Q : What does the ESC do ?
A : It controls the motor's , speed hence the current draw .

Hence all you have to do is figure out how much maximum current will your motors draw  and you have the answer to what ESC you should use , higher than the max current draw : pretty simple and straight forward right  Wink Grin
The selection of ESC is important because the BEC in most ESC's supplies power to the receiver hence should the ESC or BEC  burn out then the end result is pretty much a foregone conclusion  Roll Eyes .
