Here is the last image of my setup. I hope this helps you. It works great on mine!!!! By the way the servos you have chosen are more then enough to put the edge through its paces. If you look the recommended output for the control surface in this edge I believe is 100oz total torque. Oh yea almost forgot. Im running mine on 4.8 volts. Still no flutter of any sort.
