Of the servos you listed I would go with the 625's or the 645's. In this price range i feel these are about the best servo's. I have found that the 3305 and 3010 futaba servo's have sloppy gear sets and are not very accurate compared to the 625's. If you are willing to spend a little more the hitec 985 is a very good servo that can be used on almost any plane. I feel is one of the best servo's on the market at it's price point.
