Firstly, I found a nice set of motors: 

EMAX MT2205 II Racing Edition KV2300

$60.00 for all four.

I was looking at the specifications chart for the motors and the different

series of propellers they were using on them. Please excuse my ignorance

on such matters. But I'm trying to figure out which ESC would be optimal and

also what kind of battery would not hold the motors back. Most 4S batteries I'm

seeing are @ 14.8V. From research, it seems you take the max (W) and divide it by

the max source voltage. Correct me if I'm wrong please. My question is, 

how do I know which ESC to use (BEC, UBEC) and is a pulse width modulated ESC better

than a linear? Also looking at the spec sheet, if I run 14.8V how do I determine the type

of prop and ESC if the spec sheet only shows 12-16V ranges. Thanks. Any information

will be much appreciated.
