I've flown this plane with this same motor in various setups. It will be quite marginal for 3D work with a 3S battery and a 13x6.5 prop, it will be much better on the 14x7 but this will work a 45A ESC pretty hard. But better yet, run it on 4S as this gives much more speed for faster 3D 'stick banging' manoeuvres.

At the risk of slightly over-simplifying; diameter gives you thrust and pitch gives you speed. A larger diameter prop is also more efficient in terms of thrust generated for watt of power consumed. The 14x7 is better in all respects vs. the 13x6.5 so there are no downsides other than working the motor and ESC harder.
