I think your kv is too low for this application with 6 cells and you will need a monster prop to get it to draw the wattage you probably want. I have a 50-65 400kv Turnigy on 6 cells that I run a 16x8 APC -E prop. I also run a 50-65 270kv on 8 cells with a APC-E 18x10 and helped a newbie to test the power draw of his 580kv version on 6 cells this morning!
To get your 270kv motor to draw say 1000 or so watts I reckon the prop diameter will need to be 20 or 21 inches!
I suspect the undercarriage on the Cessna isn't long enough!
Could I suggest you work out what diameter prop you can safely run first, then the motor kv selection should be relatively straight forward. On 6 cells, a 580kv Turnigy 50-65 will be limited to either a 12 or 13 inch prop within the peak current limit, 400kv will be 15 or 16 inches and the 270kv version, as I said, much larger again.
I would also suggest that the wing area isn't that big on this model and that if you intend to use a 6 cell pack maybe a 4000mAH (or even smaller!) may be more appropriate for this model.
Hope this helps!
