CG on Sigs ultimate fun fly?

Think it will work out good. I put the elevator servo about 1/2 inch in front of the vertical stab, and going to put the rudder servo about 6 inches in front of vertical stab, or where ever it balances, Your probably to late to cut holes out of the ply nose doublers. If i build another one, i'm going to do that. what type of covering you going to use? I'm using Ultra coat transparet.
