I have used three different methods and all with good results. Pull/pull, MK bellcrank and the dual .070 c.fiber push rods with single servo's. I am seriously thinking about fourth method using dual servo's with the c. fiber pushrods on my next plane for two reasons.

1. Redundency, use the smaller digital serovs to keep weight down.
2. Keep the servo's near the center of gravity.

No long wire extentions. The c.f pushrods with a light ladder like constrution will weight about the same as two h.d. servo extentions. I will cross the pushrods going to the back to keep a near perfect straight line on the rods for smooth operation.
