I reviewed this plane a couple months ago. It is awesome. I used a ZDZ 60 and Hitec digital servos.

In my opinion, you could go with a little less motor (like a 50cc) and still get awesome performance. I would not use standard servos on anything but the throttle.
You could use Hitec 605's. They would work ok, but the rudder should have more power like a 645mg.
The 5625 and 5645 digitals are awesome and not too expensive.
Let me know if you have any more questions
