As Mike said, for a basic four or five channel aircraft, you won't get much real advantage. You won't need the additional torque, and the speed of the servos won't much matter when you are doing very basic maneuvers... bank-and-turn, climb, descend, landing, and so on. Where it really comes useful is when you have really agressive moves with a plane that is capable of doing such maneuvers.

What I should have said in my first post, they will work just fine, but are more than you will need for that type of plane.
