.......OK since you asked about the ARF, here is a recipe for success..........

Hey, thanks for the feedback! I took some of your advice. I decided not to modify the elevator, but still enlarges the rudder. I too was thinking of placing the servos in the tail section, but wanted to wait until I was further along so I could check the balance before comitting. Since you have done it, I went ahead and put the elevator servo in the rear, but kept the larger (more torque - and would not fit - I went with JR digital servos) servo up front with a pull-pull system for the rudder. Hopefully this will aid in final balancing. So happends I did pick up a 16 oz tank which is going in just forward of the CG over the wing. Since the servo tray and a bulkhead was already in the way of exact CG, I had to comprimise on the location a little.
