I did a variant on the micro servos YS performance has some neat stuff besides engines it consists of a shaft with a center horn
and 2 BB side plates (mounts the same as servos) the arms are connected to the elevator horns via short rods and clevises
the center shaft arm has a 4/40 rod connected to the elevator servo (right down the middle) no slop the dowel stick thing with the
y rods does not cut it, you can also use sullivan tubes and rods and join them at the servo end.I just got a 1/4 scale GP space walker
and they do the same thing, the elevators willl be driven by one of the above methods and the rudder going to pull/pull cables
By the way the end result looks like autoguns the end pieces look like servo tops
