rpm will be more suitable for 3d and the extra prop wash with the 12x6 will give you more control surface authority. I run the same size motor (roughly) with an 11x5.5 even though it can handle a 12x6.. the extra efficiency means I get better flight times with a smaller battery and the 11x5.5 is plenty for this plane, also spools up a bit quicker.
just my 2c
Come to think of it, I was thinking a while ago I'd love to try the 1250kv version of the 110g motor sunnysky 1000kv motor I'm running.. it can spin an 11x5.5 (just) and the stats show 43A, 2.1kg thrust, 475W, 4.4g/w efficiency at 11v... it would be awesomely punchy!!!
so maybe try the higher KV one.. I'm definitely going to eventually. anyway I'd love to hear how it goes if you do decide to go with the faster motor
