I have a Sukhoi and I balanced it with an OS 160 in the nose. I placed the servos on the plane in their correct locations and found it to be tail heavy with the elevator and rudder servos in the tail. It was still tail heavy with the rudder servo up front. I decided to mount all three servos on the servo tray under the CG. This allowed me to get the balance right.

I used a Dubro Pull-pull for the rudder and Dave Brown Fiberglass pushrods for the elevator halves (2 servos). I am not liking this setup because I had to put a slight bend in the wire on the end of the rods where they exit the fuseage. This bend is causing some flexing. I am using 4-40 wires.

I was thinking of cris-crossing the rods in the tail to the left servo controlled the right elevator and vise-versa.

Has anybody tried this?
