I went with two elevator servos in mine plus A pull/pull rudder with the cable running out the top of the fuse so the wires could attach as close to the center of the rudder as I could get. I do A lot of knife edge flying and that way I get very little flex of the rudder. I installed A YS 1.10 in mine {.60 size} so the added engine weight and the two servos in back helped out the CG.
