Picture #1 looks like my photo. I have 165 flights on this setup so far and have no complaints. Elevator trim is rarely touched. I just made sure I had two servos that were closely matched on centering. Lickily I didn't have to go beyond the handful I had laying around. I used the JR9411SA digitals which I also use on ailerons in my Brio and other planes. Just set end points equal and checked at various points and saw no need for multipoint mixing or anything like a matchbox.
