Subject: [NSRCA-discussion] Question for Electric Guru's

I have a question for you electric masters.  I purchased a new park flyer at the AMA Expo and now that I almost have it together, I am really unhappy with the motor setup.  I’m looking at replacing it with a real motor, but really have no idea how determine the right one.  This is the plane: http://www.kmp.ca/product_info.php?cPath=35&products_id=281&osCsid=4d214aaee43cca1e5e153afdb13c943c with a 3-bladed prop (no clue as to pitch).
Specs:
Wingspan: 55"
Flying Weight: 1.9 kg, 4.2 lbs
Wing Load: 50g/dm2
4pcs 9 gram servos (included)
Brushless Powered: Powerful 3648 outer runner brushless motor KV600 (included)
45A ESC (included)
3 Bladed Scale prop and Spinner (included)
Battery: 2200Mah, 14.8V.20C (NOT included),
Construction: Super Strong EPO FOAM

Motor that came with it is this:  http://rc-castle.com/shop/product_info.php?products_id=1678  Spinner backplate doesn’t fit right and, of course, I have no clue what the prop is to replace it.
FMS 3648 600Kv Outrunner Motor For 1.4M Warbird

I have 3 – 2200Mah, 14.8v batteries I’d still like to use with it, but if I have to change, then so be it.

The real question I have is what is the right way to pick a motor for a given aircraft?  Any suggestions as to a replacement motor?

Any help would be appreciated.

Thanx,
