xuzume has point with the purpose of the beef. It will fly but it is going to change how it flies.
Some attributes you will gain:
1. Higher top speed.
2. Better control authority at higher air speed
Some attributes that will decrease:
1. Agility at lower speeds (high alpha control)
2. easy of take-off
Why? Because the higher kv, faster rotating and lower torque motors mean you have to use a smaller and shallower prop which will have a harder time overcoming the weight of the plane and will move less air over the control surface without significant air speed.
Don't be discouraged by that though. I am managing a fun time with my FT Flyer on a 2806 1650kv motor with a 7x4 prop and a 2200mah battery. I'm not a very experienced pilot either it's only my second plane and I've only been flying for about 2 months.
