I would strongly advise against the servos all inside. I did it, way too nose heavy, took too much weight to get it to balance, and the landing gear isn't all that hefty to begin with. I just recently moved the elevator servos to the rear, left the rudder servo inside next to the throttle, and didn't add any weight at all to balance. It flies much better, but still seems heavy / fast on landing. This picture is with all the servos mounted in the inside, which was what I felt was the cleanest looking installation. From left to right, elevator, rudder, throttle, elevator. This also doesn't require the use of a servo reversing cable.
