The stock motor is an 870kV, and your new Power-Up-25 is a 950kV. Higher, but not dramatically higher. The difference is only 80kV, and 80kV X 11.1V = about 900 RPM's higher. That won't equate to much additional speed.

Depending on the new motor's efficiency, you may see a little longer flight times. The big difference will come when you decide to try 4s. THAT will give you significantly more speed. Just remember, though, the Apprentice is a trainer, not a pylon racer. Its huge wing provides a lot of lift, but also creates a lot of drag.
Isn't the stock motor a 15 size vs. his new 25 size ??? I would think it should be somewhat faster
