Check out the link: Northstar Mods, tell me what you think. I built a tray type of deal that goes in the back end of the pod behind the gas tank. It holds the elevator and throttle servo that has very short push/pull rods to the control surface and engine. Works very solid. I also recommend two servos for the ailerons. Run them as standard ailerons or mix them as mentioned before. There's plenty of room up front for it and you'll need weight up there anyway, might as well make it usefull.
