Default Motor, Speed control and other questions

Can anyone tell me the difference between the Hacker A10-12S and the A10-15S?

I was thinking on pairing either one of these motors with a Hacker X-5 Brushless Motor Speed Controller ESC 5A and a Thunder Power RC Pro Lite 480mAh 7.4V 2 Cell Li Poly 2s 480 Lithium Battery w/JST...

Any suggestions?

I am new to electric planes and am building a Millennium Micro SSX.

The only difference is the Kv - the 12S is 2900Kv, the 15S is 2320Kv - both have the same max amps (4A), both run on 2s, but the 12S is suited to a 6x3, whereas the 15S can spin a slightly larger prop (7x4). You'll get more thrust with the 15S and the 7x4.
