Oh, I see. Both servos are basically on the centerline of the model, at different heights? But that would require placing one in front of the other, with the higher one behind (actually, toward the nose) the lower one, yes?

Sure, I can see where that would work fine. But unless you were building a model from scratch, or a kit, that would require some surgery to the servo tray. Probably about the same effort needed to fabricate the bellcrank assembly...

Actually, I do have my elevator servo "stepped"; it is raised off of the servo tray by spruce blocks.
