Hey blue if you got one of the new edge the elevator servos are not in the spot that that picture it's showing you,, they are forward and up a bit very close to the stab.
The rudder servo would be the perfect spot to install the elevator servos using 1.25'' to 1.5'' servo arms pointing up and you would have a perfect 90deg. on the linkages but you can't install them there because the servos will be on the way of the pull-pull cables for the rudder.
